1. What is the push button switch?
Different types of the push button switches
The push button switch is a hand-operated electrical or mechanical device that is used for switches or switching circuits.
It is among the diverse types of switches and one of the specialized forms that have multiple configurations and an array of variations.
It is also called as the push switch types, or the round push button switch.
Some characteristics of the push button switch that can be considered as its basic variations are its bushing diameter, colors, material, shapes, actuator type, illumination colors, and terminal types.
The push button switch has other variations and configurations allowing you to find the most suitable switch for your application requirements.
Fun Fact: The push button switches may have inspired the development of Amazon’s Alexa
In 2014, Amazon developed the first IoT (Internet of Things) called Amazon’s Dash button.
These are the programmed small push button devices that you can use to reorder your past purchases and the items will be delivered to your doorstep.
For example, if you have run out of laundry detergent, you simply press the push button switch of the detergent to replenish your laundry soap then wait for its delivery.
You can also mount these push button switches around the house where the products are commonly used.
The dash button also comes with a scanner device that can scan the barcodes of the products you would like to reorder and it also has a microphone if you prefer to verbalize the products that you need to order.
However, these dash buttons eventually got discontinued in July 2020 due to the development of a scheduled reordering of products on Amazon’s website.
The concept of the Amazon’s Dash button series was part of the inspiration of the development of Amazon’s Alexa, the first ever voice command smart speaker.

2. Who invented the push button switch and for what purpose?
The birth of the push button switch can be credited to the “quick-break” switch technology used for light switches invented by John Henry Holmes in 1884.
It overcame the electric arcing problems of its predecessors like the gas and arc lamps which is a serious fire hazard problem during that time.
In 1910, the electricity network expanded in more cities and this enabled households to have access to electricity and because of this, the push button switches were predominant in many homes.
The push button light switch or push button wall switch is the second to use the push button technology since the battery-powered flashlight was the first to use push buttons as its on and off switch.
In the following years, the push button switch was used in other applications such as in radios, doorbells, Kodak cameras, calculators, cash registers, and in home appliances like the dishwashing machine and laundry machine.
Some early applications of the push button switch

There maybe other applications which are not included in this list but this long list already proves how versatile the push button switches are.
Different applications of the push button switch
4. What are the parts and components that make up the push button switch?
There are parts and mechanisms of the push button switch that works together to perform as one unit.
Each one is responsible for a specific role to help the push button switch work in its optimum performance.
You may already have an idea about the main parts or sections of the push button switch such as its head or the button, its shell or body, as well as its terminals or also called pins.
But some other parts and components are also important to know since some of them can help you identify the kind of push button switch you need.
This is the mechanical part of the push button switch that you can physically actuate by pressing it.
The actuator of the push button switch is also called the head or the button.
It is usually facing the user when mounted and can come in different shapes, colors, and logos.
The different shapes of the actuator can be the domed, concave, chamfer, raised, recessed face, or flat head like the flat push button switch.
While some actuators even have a laser etched feature like the power push button switch.
The color of the actuator is usually the color of the entire push button switch unit and it can be a white push button switch, chrome, natural, black, red, blue, green, yellow, orange, gold, etc.
But there are kinds where the actuator and the body of the push button switch have a different color such as a red push button where the actuator is red colored while the body is typically black in color.
This contains the internal and external parts of the push button switch and keeps them together in one unit.
It is also called the shell or the enclosure of the push button switch.
These are the small rods attached at the bottom of the push button switch which is made from a conductive material.
They are also known as push button switch terminals.
There are several kinds of pins available such as solder lug pins, screw type pin, blades or spade terminals, feed-through, etc.
Typically, the wires are connected to these pins through soldering or other methods based on the type of push button switch.
Some types of push button switches are lacking pins but instead, they have integrated wires that remove the need to connect wires anymore.
For example, if it’s a 3 wire push button switch then there are 3 wires integrated to the switch.
Pins can come in two up to 6 pins or more depending on the type of push button switch’s electrical configuration.
This refers to the types of push button switch with LED can come in different colors and designs.
The push button switch has an integrated LED chip that emits light when you press the actuator or it remains lit up even when not actuated depending on how you wired it.
Good examples of this are the illuminated push button switch and the LED push button switch.
You can find dot illuminated, ring illuminated, full illuminated, power backlit symbol, ring and power symbol illuminated, and backlit label which can help indicate the function of the push button switch.
This is the rubber ring that helps seal the mounting of the push button switch to prevent any entry of outside elements such as dust or water to the backside of the switch.
It is inserted through the body of the push button switch and positioned under the actuator before inserting the switch through the mounting hole.
- Mounting flange
This is the hexagon shaped metal ring that helps secure the mounting of the push button switch.
It is generally inserted through the back of the panel and fastened along the grooves of the push button switch.
There are push button switch types where the mounting flange is fastened via the front side along the grooves that are located along with the head of the switch.
These are the depressions around the push button switch where the mounting flange is fastened.
- Coil spring
This is the metal spring that stores mechanical energy and responsible for enabling the movement of the actuator of the push button switch.
When you press the actuator of the push button switch, this compresses storing mechanical energy.
When the actuator is released, it ricochets back to its relaxed state.
This will be determined by the type of switch action of the push button switch which you will learn in a moment.
The contacts are the electrical conductors positioned inside the push button switch.
In a push button switch unit, there are movable and stationary contacts.
When the push button switch is pressed, the movable contacts touch the stationary contacts that enable the flow of current.
But this depends on the push button switch’s normal contact position since another type has the movable contacts normally touching the stationary contacts and this connection is broken when the actuator is pressed.
- Module unit
This specially manufactured assembly unit is present in special types of push button switches.
It replaces the movable components of the push button switch which enables it to have a longer service life.
- Touch sensor technology
This type of technology is present in “touch” push button switches where it reacts to touch or slight energy and does not require a significant amount of physical pressure to actuate the switch.
There are other push button switch parts or components that may not be mentioned in this list. However, these are the most common ones that play a critical role in the performance and structure of the push button switch.
Parts of the push button switch
5. What are the significant attributes of the push button switch?
To understand the many varieties of the push button switch better, you need to learn its different attributes.
These attributes include the structure of the switch and its electrical characteristics.
- Push button switch structure
This refers to the push button switch’s construction which is considered of paramount importance.
How the push button switch is assembled will determine if it is suitable for an application or not.
- Push button switch circuit configuration
The circuit configuration signifies how many poles and throws, as well as breaks a push button switch has.
Poles, throws, and breaks can be single, double, and there are even complex switches with more circuit configuration.
- Push button switch contact type
These are also known as the switch actions of the push button switch which describes the action of the switch when actuated.
- Push button switch contacts and terminals plating
These refer to the materials used to reinforce the contacts and terminal components of the push button switch.
The contacts and terminals plating can be made of nickel, silver, or gold.
Solder or tin is also used for terminals plating.
- Push button switch mounting styles
These are the methods in how the push button switch is installed on a device, equipment, panel, etc.
An appropriate mounting style should be chosen to ensure the compatibility of the push button switch to its application.
- Push button switch service life
The service life of the push button switch refers to how many switching operations it can perform before it shows signs of its end of life.
- Push button switch current rating
This refers to the ampere capacity of the push button switch which is usually measured in amps (Amps) or milliamps (mA) and the type of current it is capable of handling (AC or DC).
For example, 10a push button switch or 10 amp push button switch, 15 amp push button switch, 16 amp push button switch, 20a push button switch, 50 amp push button switch, or 60 amp push button switch.
Sometimes you can find high amp push button switch kinds.
- Push button switch power rating
This relates to the power rating that the push button switch can handle during operation.
It is measured in watts (W) or volt-amps (VA).
Exceeding this rating cause build up heat within the push button switch which can result in a performance failure or safety risk.
- Push button switch voltage rating
This pertains to the maximum voltage rating that the push button switch can handle during operation.
It is measured in volts (V).
When this rating is exceeding the can result in the switch to arc-over or arc discharge which in turn can cause a short circuit, operation failure, and safety hazards.
For example, 5v push button switch, 12 volt push switch or 12v dc push button switch, 24v push button or 24 volt push button switch, 110 volt push button switch, 120 volt push button switch, 220 volt push button switch, 230v push button switch.
- Push button switch dielectric strength
This provides the strength of the dielectrics or the polarized insulating materials of the push button switch.
It is measured in volts (V) which pertains to its capacity and going beyond could degrade its insulation ability.
- Push button switch IP and NEMA rating
The IP (Ingress Protection) and NEMA or also known as the National Electrical Manufacturers Association are the standardized enclosure guidelines to determine what kind of environment a certain push button switch can withstand.
There are stricter ratings that are applied to hazardous environments.
Other push button switch attributes are not listed here but could be of importance to your application.
You can find more detailed push button switch attributes in its technical specification sheet or in its push button switch datasheet.

6. What are the types of push button switch actions and their applications?
Switch actions pertain to the response of the switch when actuated and after the actuation.
Each switch action has certain applications that it is best suited for and some applications are not compatible with the other switch action.
This is why it is essential to choose the correct push button switch action to avoid more financial expenses, delay in business operations, customer dissatisfaction, etc.
There are two categories of push button switch actions and these are:
This is also called a non-latching switch that when physically actuated, causes a brief alteration in the state of the electrical circuit but once the pressure is lifted, the electrical circuit returns to its original state, and the switch springs back to its normal position.
This kind of switch action is ideal for doorbells, elevator call buttons, intercom buttons, vehicle horn buttons, and many more applications that require momentary switch action only.
Also known as the maintained switch that causes a sustained change in the state of the electrical circuit when physically actuated.
It remains in that state unless the switch is actuated again.
You will generally see this type of switch used in applications such as light switches, flashlights, electrical equipment, kitchen appliances, emergency stop buttons, and other applications that require latching switch action instead of momentary.
Momentary and latching push button switch
7. What are the normal contact positions of the push button switch?
The normal contact positions refer to the un-actuated state of the push button switch or the default condition of the push button switch without any physical contacts.
There are two normal contact positions of the push button switch and they are:
The normally open push button switch has an open circuit when un-actuated in which the contacts are not connected and there’s no flow of current.
The contacts are only connected when you press the actuator and this condition enables the current to flow hence actuating the push button switch.
The normally closed or NO push button switch has a closed circuit when un-actuated and the contacts are connected allowing the flow of the current actuating the switch.
The connection of the contacts is broken when the actuator is pressed which also breaks the current flow causing a change in the switch operation for example from “go” state to “stop” state.
Normally open and normally closed push button switch symbol
8. What do poles and throws of the push button switch mean?
Sometimes you see these terms on the product description of the push button switch and wonder what they mean.
But some terms are abbreviated such as SPST, SPDT, DPST, and DPDT.
These are the electrical configurations or sometimes referred to as the switching functions of the push button switch.
Others are more complex but we will focus on the most common ones.
The SPST abbreviation when expanded reads Single Pole Single Throw which is also known as the basic on off switch or the two way switch.
The SPST push button switch has a single terminal for its input and output since it is the basic switch.
This means Single Pole Double Throw which is sometimes referred to as a changeover switch or as the break-before-make switch and can be used to control two circuits.
The SPDT push button switch has a single input terminal and since it has a double throw, it has two output terminals.
It is also sometimes called double throw push button switch.
- DPST push button switch
This stands for Double Pole Single Throw which is also called a double pole switch or sometimes comparatively similar to two SPST switches in a single device.
The DPST push button switch has two poles which means that it has two input terminals while having a single throw means it has a single output terminal.
This term when expanded means Double Pole Double Throw and can be compared to two SPDT switches in one device.
The DPDT push button switch has double poles which means it has two input terminals while double throws mean it has two output terminals.
Moreover, you can use whichever of the two output terminals or the two input terminals alternately.
Different types of the push button switch in an electrical circuit
9. How does the push button switch compare with other types of switches?
The push button switches are different from other types of switches due to several factors.
- The push button switch does not require more physical energy to actuate
The physical force that’s needed to actuate the push button switch can be comparable to the force exerted when typing on a computer keyboard.
You only need to exert about 0.5 Newton force to press the actuator of the push button switch, unlike other switches where you need to perform complex actions to actuate the switch, therefore, requiring more physical energy.
For example, the rotary switches where you need to rotate the knob to select the function you need or slide switches that sometimes have strong resistance so you need to exert physical force to slide the lever to the other side.
- The push button switch prevents accidental actuation
The push button switch is designed to avoid unintentional actuation which is a safety feature that is necessary for some business operations.
Unlike other switches such as the toggle switch that has a lever which can be accidentally flipped and cause unnecessary process.
- The push button switch is aesthetic
The push button switch has a better appearance when compared to other switches.
It offers a wide array of types and designs suitable for many applications and environments.
For sure you will find your preferred or ideal color and design that is appropriate for the type of surface where the push button switch is going to be mounted on.
There are more advantages of the push button switch such as:
- Long life
- Space saver
- Quick install
- Zero maintenance
- Adaptable to any kind of environment like:
- Damp places
- Water prone places
- Saline outdoors
- Corrosion prone areas
- Windy and sandy places
- Oily areas
- Perilous zones
You may discover more benefits of the push button switch during your experience with it.

10. What are the physical attributes of the push button switch?
The push button switch has several physical attributes that are vital to know when you’re shopping for it.
Here are the most common physical attributes of the push button switch:
- Bushing diameter – This varies from 8mm up to 40mm or bigger.
- Shapes – Round, square, or miniature push button switch.
- Colors – Different colors of the push button switch such as chrome, natural, white, blue, red, black, yellow, orange, green, gold, etc.
Without knowing this information, you could end up purchasing the wrong size or kind of push button switch.
Different colored push button switches
11. What kinds of materials are used to make the push button switches?
Several materials are used to manufacture push button switches and it could be any of the following materials:
- Stainless steel
- Aluminum (Natural, anodized)
- Brass (Natural, nickel plated, or gold plated)
- Silver alloy
- Copper (Nickel plated or gold plated)
- Other materials as needed
Among these materials, stainless steel is the most common and preferred for push button switches due to its robustness and natural anti-corrosion properties.
An example of this is the metal push button switch which uses stainless steel material.
Stainless steel is categorized into many grades depending on its composition since it is mixed with other materials or minerals to enhance its properties.
These grades are designated by the SAE (Society of Automotive Engineers) hence you will find that stainless steel grades are labeled as SAE then a set of numbers representing their chemical composition.
For push button switches, two stainless steel grades are widely used:
- SAE 304
This stainless steel grade is the leading material used in making the push button switches.
It contains nickel and chromium boosting its anti-corrosion and heat resistant properties.
Because of its enhanced properties, this type of stainless steel is ideal for the humid environment and tough conditions.
- SAE 316L
This is the next grade of stainless steel that is also used in manufacturing push button switches.
It has added molybdenum and small amounts of silicon, sulfur, and phosphorus which makes it ideal even for a saline environment.
Stainless raw material in different sizes
12. What does the IK10 seal in push button switches mean?
The IK10 that you see in the product description or the packaging of the push button switch means it is a tough and heavy-duty switch.
These push button switches were able to surpass a series of tests called the Impact Protection tests that measure the level of protection provided by its enclosures against different levels of impact during ambient and extreme temperatures.
To be specific, these tests are:
- Charpy Impact test or Charpy V-notch test – The push button switch is placed in a Charpy impact test machine and subjected to the impact of a pendulum with determined mass and length while being exposed to harsh temperatures.
- Drop Weight test – Includes tests such as dropping the push button switch from a higher ground and striking it with different types of hammer such as the pendulum hammer, spring hammer, or the free-fall hammer.
After which, the push button switches are designated the impact rating seal abbreviation “IK” followed by the number representing the level of its protection level.
The IK10 is the highest protection level which means that it can stand up to 20 joules of impact and will still produce prime performance.
An example of this is the anti vandal push button switch which is specially made to be tamper-proof and durable to resist any type of abuse.
The IK10 chart
13. What does a push button switch with IP69K seal mean?
A push button switch with an IP69K seal means that it is a waterproof type of switch.
The IP69K is the highest protection rating acquired from the Ingress Protection test.
This involves exposing the push button switch to outside elements that can penetrate it and cause internal damage.
The IP seal is followed by two numbers which represent the degree of defense that the push button switch provides against solid and liquid elements.
The first number is for the protection against solid elements such as a small solid object down to the small dust particles.
While the second number is for the protection against water, such as water drops, a splash of water, water jets from any angle, temporary flooding, temporary and permanent water submersion.
An example of this is the Waterproof push button switch.
The IP rating chart
14. What are the special types of push button switch?
Other than the anti vandal and the waterproof push button switches, there are also other special types of push button switches and these are the:
The piezo push button switch is also known as the piezo touch switch that uses the piezo principle to complete its circuit.
The piezo principle refers to the piezo electric effect where the mechanical energy is converted into electrical energy.
The piezo push button switch has an integrated piezo electric element that produces an electric charge which energizes the semiconductor unit known as the FET or Field Effect Transistor when the actuator is pressed.
Then the FET actuates the piezo switch’s module and allows the flow of the current.
After the current has been dispersed the FET de-energizes, goes back to its resistive mode until it is energized again.
The capacitive push button switch is also referred to as the “true touch” switch or the push button touch switch.
Technically, the capacitive push button switch is not actuated by pressing its actuators but rather via a simple touch of a finger because of its touch sensor technology.
Therefore it does not require much energy to actuate.
The touch sensor technology comprises a non-conductive panel and an electrode.
The actuator’s surface retains a charge and discharge cycle forming a capacitance field.
When an object with an electrical charge touches the actuator, the capacitance field is disrupted and detected causing the actuation of the push button switch.
The human body carries a small amount of electricity which is why a slight touch of a finger can actuate the capacitive push button switch.
This also happens when you are using any object to actuate it as long as you are holding the object except for those which are considered insulators that can block the electricity flow such as fabric, wood, or a piece of stone.
Both the piezo push button switch and the capacitive push button switch have no mechanical parts which generally classifies them as switches with really long service life making them suitable for industrial operations.
Moreover, they are sealed switches which make them ideal for outdoor applications too.
Both of them also have integrated wirings which remove the need to solder and shorten the installation time.
Capacitive push button switches
15. How to avoid accidents when working with push buttons switches?
Push button switches are generally safe since they pass certain safety requirements before they are sold in the market.
However, it is still recommended to conduct some safety measures to avoid accidents.
Below are some of the precautionary measures you take when working with push button switches:
- Work in a well-lit space.
- Switch off the power supply or the mains if you’re working with live wires to connect to the push button switch.
- Avoid making contact with the parts that have live-flowing current.
- Conform to the recommended switch rating from the manufacturer.
- Inspect the push button switch and check if there is any damage or signs of corrosion which could mean that it is not a good switch to work on.
- Refer to the manufacturer’s wiring instructions to ensure proper wiring.
- Check your surroundings for any flammable gas which could cause an explosion when a spark is ignited from the push button switch.
Sometimes this safety guide is included in the packaging of the push button switch or available on the website of the manufacturer.
16. What are the ways to mount the push button switch?
As mentioned earlier, there are mounting styles of the push button switch.
The mounting styles determines as to how the push button switch should be mounted on a panel, equipment, or any surface.
Some push button switches are designed to be mounted in a specific way and not for any other mounting styles.
Here are the types of push button switches with specific mounting styles:
This is the type of push button switch that is mounted on a panel and it can be done in two ways.
One is mounted at the front of the panel called the front panel mount push button switch.
Its actuator has grooves around it where the mounting flange is fastened.
While the other mounting method is where the mounting flange is fastened at the back of the panel hence it is called the rear panel mount push button switch.
This is the type of push button switch that is generally mounted on a printed circuit board (PCB) and would usually have a smaller profile than the regular type of push button switches such as the low profile push button switch or the 10mm push button switch which are perfect for this mounting style.
This is the type of push button switch typically has its actuator flushed with its base or enclosure.
Because of this, they are generally ideal if you would like to have better surface clearance or if you want to install a push button switch cover for added protection.
Before mounting the push button switch you need to consider the following reminders:
- Ensure that you have purchased the right mounting style for your application.
- Check the mounting method recommended by the manufacturer.
- Make sure that the diameter of the push button switch fits the mounting hole or vice versa.
- Find out if the space behind the panel will accommodate the length of the push button switch.

17. How do you test the push button switch if it is good or bad?
It is necessary to know how to test the push button switch if it’s a good switch or a bad one to make sure that it will work after you have connected wires to it or mounted it.
In this process, you will need the following:
- The push button switch
- An ohmmeter
Here’s how you can test the condition of the push button switch:
Test the ohmmeter first
- Testing the ohmmeter first ensures that it is working properly before using it to test the push button switch.
- Connect the test probes into the ohmmeter, one red for positive and the other one is black for the negative test probe.
- Check if both probes are okay by putting both of their metal tips together.
- The needle of the ohmmeter scale should move while you are doing this, and it should at least move to 1 ohm or less.
- If you don’t see any movement in the needle, check the connection of the probes to the ohmmeter if they are properly inserted.
- If the push button switch connection to the probes is fine the ohmmeter could be broken.
- If the needle moved but it is higher than 1 ohm, check if the settings of the ohmmeter are correct and if the settings are okay, the ohmmeter is not good to use for this process since it may produce a different result.
Test the push button switch
- After testing the ohmmeter, it is now time to test the push button switch.
- Touch one of the pins of the push button switch using the red test probe and touch the other pin using the black test probe.
- The ohmmeter will show 1 ohm if the push button switch’s state is “on”.
- The ohmmeter will display “OL” which means that the push button switch’s state is “off” and also indicating that it has high resistance.
- Do this twice or thrice to confirm the condition of the push button switch.
Another way to test the condition of the push button switch is pressing its actuator while the probes are still connected to show the scale needle change to 1 ohm and “OL” alternatively.
If the scale does not show any changes, the push button switch could be faulty.
You can have it repaired or replaced if it’s within warranty.
Bad push button switches generally happen when it is poorly made.
This is why it is better to choose a high quality push button switch to avoid getting a bad switch.

18. How to properly connect the wires of the push button switch?
Connecting the wires to the pins of the push button switch depends on its terminal type.
For solder lug, you can connect the wires by either soldering, using a push button switch socket connector, or female spade connectors.
For screw type pins, the wires are clamped in between the screws.
How you can want to connect the wires depends on you whichever you think is more convenient.
But if you prefer to solder the wires to the push button switch, here are some suggestions to help you connect them properly without melting the pins.
- For more precision soldering, you can use a fine point solder to avoid soldering the pins together.
- Start with low heat and increase gradually until the heat can melt the lead since soldering the wires to the pins with too much heat may cause the pins to melt.
- Solder some lead on the pins to prevent shrinkage before soldering the wires.
- Tilt the solder at a 25 degrees angle while soldering each wire to the pins.
- Solder within 1 to 2 seconds gradually until the wire is sturdily connected to the pin.
- Start soldering one pin first, before connecting another wire to the next pin to avoid the lead from touching the other pins.
Tip: To have more secure and stable soldering:
- Strip about an inch of insulation from the each tips of the wires.
- Twist and insert the exposed part through the hole of the pin.
- Then fold the wires and twist them together.
Knowing these tips can help you connect the wires faster and finish the push button switch assembly of the push button switch immediately so you can enjoy your newly mounted switch right away.

19. What are the ways to wire the push button switch with LED?
Generally, the push button switch with LED can be wired in two ways.
You can wire it with the LED always “on” or you can also wire it to have the LED lit up only when the actuator is pressed.
For example, you’ve purchased a 5 pin push button switch, and you want the LED of the push button switch to be always “on”.
Here’s how to wire a push button switch with LED that is always “on”:
- Connect a wire between the NO pin and the positive pin.
- Then link another wire from the positive pin to the device.
- Connect a separate wire from the common “C” pin to the power source.
- Lastly, connect another wire from the negative for the ground.
And if you prefer to have the LED lit up only when you press the push button switch, you can use the following guide:
- Connect a wire from the NO pin to the positive pin.
- Then connect a separate wire from the positive pin to the power supply.
- Take a different wire to connect the common or “C” pin to the device.
- Finally, connect another wire to the negative pin for the ground.
You can also find the wiring instructions along with your push button switch order or posted in the product listings of the manufacturer’s website.
If not you can request a copy of the wiring guide from your manufacturer.
