1. What is the reset push button switch?

Example of the reset push button switch

A reset push button switch is a special type of push button switch whose main function is to reset an operation or a process.

It is also called the push button reset switch, reset button switch, reset switch button, reset push button, push button reset, momentary reset, or momentary reset switch.

The reset push button switch also has different types; they vary in color, shapes, sizes, configurations, and many more.

Similar to the other types of push button switches, the reset push button switch also has parts that make up its unit such as the following:

• Actuator

It is also called the head of the reset push button switch or the button which you press to actuate it.

This is a movable part of the reset push button switch which has different colors, styles, and symbols.

It can also be an illuminated type which also has several kinds like different colors and styles.

• Body

This is otherwise known as the shell of the reset push button switch or the enclosure.

Its main purpose is to protect the reset push button switch, its internal parts, and hold the parts together as one unit.

• Terminals

Generally known as pins of the reset push button switch where the wires are connected to by soldering or crimping.

• Mounting flange

It is the hex shaped nut generally made from metal material that helps secure the mounting of the reset push button switch.

The mounting flange is inserted either through the terminal side of the reset push button switch or through its actuator for the front panel reset push button switch.

It is fastened along the grooves around the shell of the reset push button switch

• O-Ring

This is also called the rubber ring which is positioned right below the reset push button switch’s actuator before securing it with the mounting flange.

This prevents dust and water from seeping in reaching the back of the panel.

• Contacts

The contacts are located inside the reset push button switch and they are either movable or fixed.

The movable contacts are attached underneath the actuator.

When you press the actuator, the movable contacts are pressed down and connected to the stationary ones attached to the terminals of the reset push button switch.

When this happens the reset push button switch is actuated.

• Coil Spring

Sometimes called the spring steel which is a spiral metal positioned inside the reset push button switch.

This enables the actuator to move down when you press it and enables it to spring back up when the pressure is released.

2. What are the different varieties of the latching push button switch you can purchase in the market today?

This depends on what are the latching push button switches available on your selected manufacturer.

Some manufacturers may have limited types of the latching push button switch while some offer a wide range of varieties you can choose from.

Here are some of the types of the latching push button switch you can find in the market today:

• Piezo reset push button switch
• Capacitive reset push button switch
• Anti vandal reset push button switch

When choosing your reset push button switch, you need to be familiar with the common push button switch description or characteristics before anything else.

This basic information may be just the basics but when they are taken for granted, you can make a wrong purchase and run into issues eventually.

The basics are the sizes, shape, colors, and terminals.

Here are the varieties that you may find available in the market.

The reset push button diameter sizes are from 8 mm, 10 mm, 12 mm, 16 mm, 19 mm, 22 mm, 25 mm, 30 mm, 40 mm, or bigger.

The actuator shape of the reset push button switch can be flathead, raised or high raised, squarehead, chamfer head, concaved, or laser etched.

There are different illumination styles for the actuator too such as non-illuminated, dot illuminated, full illuminated, large or thin ring, ring and power symbol, power backlit symbol, and backlit label.

The terminals are usually solder lug and screw type but you can also find those with flying leads, with quick, connect blade type, and feed through style.

3. What are the standard colors used for the reset push button switch?

Not many people know about this but push button switches with important functions follow a certain color code to indicate what it is used for.

According to IEC 60204-1 of 1997, push button switches should be color coded for compliance.

The same standard is applied on reset push button switches.

The following are the standard colors used for reset push button switches:

• Blue
• White
• Grey
• Black

Reset push button switches also act as a stop and off button where the colors white, grey, or black are preferred with black as the primary option.

The green color should not be used for the reset push button switch as this is universally known to be a start, go, or “on” button.

The other colors that are used for other functions besides the reset push button switch are:

• Emergency stop button – Red
• Stop or “off” switches – Black, grey, white, and red is also permitted given that it is not beside an emergency button which color is red as well.
• Start or “on”, Stop or “off” – White, grey, and black, except red, yellow, or green.
• Start and stop operation, hold-to-run – White, grey, and black except for yellow, red, and green.

Example of a black start push button switch

4. What are the different color options for the reset push button switch with LED?

While there are standard colors you can comply with, you still have the option to choose a different color especially if the reset push button switch is for your personal use.

You can find a wide variety of colors such as red, green, yellow, orange, white, bi-color, or tri-color options.

5. What kind of applications do you need a reset push button switch for?

The most common reset push button switch applications are for computers, game consoles, small appliances, factory control panels, small appliances, and many more.

The reset push button switch is also found in different types of industries such as beauty and cosmetics, power plants, media equipment, telecommunications, musical instruments, automotive, aerospace, and many more.

Diffferent applications of the reset push button switch

6. How many years can a reset push button switch last?

There are many factors that can affect the service life of the reset push button switch.

First, it depends on its quality.

A high quality reset push button switch generally lasts longer than those with poor quality.

It will have about 1 million mechanical life cycles and around 200 thousand electrical life cycles.

Those high life cycles can equate to a lot of years more than the average human life.

But despite that, sometimes how the reset push button switch is used can also either prolong its service life or shorten it.

Factors such as the manner of usage, rapid shaking of the equipment where it is installed, exposure to extreme temperatures beyond the allowed temperature range, or even a simple human error can cause the reset push button switch to function poorly or stop function altogether.

To avoid this, you can refer to the technical data sheet provided by the manufacturer for your reset push button switch.

7. What type of materials do manufacturers use to make the reset push button switch?

The most common material that is used to manufacturer the reset push button switch is stainless steel.

But it is not just any kind of stainless steel since there are many kinds with different compositions and they are classified into stainless steel grades.

The reset push button switch is either made from any of the most commonly used grades of stainless steel which is the stainless steel grades 304 and 316L.

• Stainless steel grade 304

Many manufacturers use this stainless steel grade because it has well anti heat and corrosion proof properties.

This kind of stainless steel includes some chromium and nickel that help improve its properties.

It is also called the 18/8 stainless steel and is also used to manufacture small kitchen tools and appliances, automobiles, and so on.

• Stainless steel grade 316L

The second most used stainless steel grade.

It is mixed with some amounts of molybdenum, chromium, iron, phosphorus, silicon, sulfur, and nickel.

This type of stainless steel is usually recommended for near saltwater application thanks to the mixture of different chemicals that boosts its own protection in a saline environment.

There are other materials that manufacturers use to make the reset push button switch such as the following:

• Anodized aluminum
• Silver alloy
• Gold or nickel-plated brass
• Gold and silver-plated copper
• Silicone
• Ceramic
• Polycarbonate
• Nitrile
• Polymer
• Acetal

Stainless steel raw material

8. Is the reset push button switch NO or NC?

If you were wondering if whether the reset push button switch is NO or NC, it is both.

It can even have a switch combination of 1NO, or 1NC, or 1NO1NC, and 2NO2NC.

There are only two main types of contact positions that apply to most push button switches which include the reset push button switch.

The contact position is the usual position of the reset push button switch before it is actuated.

The two contact positions are the following:

• Normally open or NO reset push button switch

The usual position of the contacts is not in contact with each other therefore the current is not flowing.

When you press the actuator, the contacts will “connect” hence the current will flow and the reset push button switch is activated.

• Normally closed or NC reset push button switch

In here, the contacts are usually positioned connected therefore the current is flowing freely and the reset push button switch is actuated.

When the actuator is pressed, the contacts break, and the current flow will stop thus stoping the actuation of the reset push button switch.

9. Does the reset push button switch have different switch configurations in an electrical circuit?

Yes, you are correct.

The reset push button switch also has different switch configurations in the electrical circuit just like the other push button switches.

These are the number of poles and throws that the reset push button switch has.

The number of poles indicates the number of circuits that the reset push button switch can control while the number of throws pertains to the actuator’s positions.

Here are the different switch configurations of the reset push button switch in an electrical circuit.

• SPST (Single Pole Single Throw)
• SPDT(Single Pole Double Throw)
• DPST(Double Pole Single Throw)
• DPDT (Double Pole Double Throw)

10. What you should check before installing the reset push button switch?

There are some things you should check before installing your reset push button switch.

They may seem unimportant for now, but doing these suggestions will prevent you from encountering issues later on.

Here are some things you can do to prepare for the mounting of the reset push button switch:

• Check the mounting recommendation of the manufacturer – A leaflet or product information sheet may come together with your reset push button switch order that contains the recommended mounting method and other important details from the manufacturer.
• Make sure that you have the right size of the reset push button switch – Measure the diameter of the reset push button switch and its length then think about how much space it will require behind the panel.
• The surface clearance – Since this is a reset push button switch, think about if you need a switch cover to avoid accidental pressing of the switch or will you leave it open for easy access.
• The thickness of the panel – The manufacturer generally provides their recommendation of the panel’s thickness to avoid having a panel too thick or too thin which can impact the performance of the reset push button switch.

Checking the size of the reset push button switch

11. What is a piezo reset push button switch and why it is different?

A Piezo reset push button switch is one of the kinds of reset push button switch but it uses the piezo principle to actuate.

It is generally made from stainless steel, polyamide, or acetal.

When you press it, the piezoelectric element inside it produces a charge which energizes the semiconductor device that actuates the unit.

There are also different sizes, colors, and designs that you can choose from.

It offers many distinguishing features when compared to other standard push button switches.

Because it has no moving parts, it is tough with anti wear and tear properties.

It is also made to be completely sealed against any contaminants or moisture making it weatherproof, and anti corrosive.

Therefore it can last for millions of operations.

Example of a piezo reset push button switch

12. What is a capacitive reset push button switch?

A capacitive reset push button switch is a touch sensor type of reset push button switch that actuates when it detects changes within its capacitance field.

This occurrence is also called touch sensor technology.

The capacitive reset push button switch also has a variety of kinds when it comes to its sizes, colors, as well as its designs.

There are also illuminated types with different illumination designs.

Because the capacitive reset push button switch does not have any mechanical parts, it offers plenty of benefits such as being robust, durable and wear proof.

Example of a capacitive reset push button switch

13. What is the purpose of the reset push button switch in trains?

The reset push button switch is one of the important buttons in the motorman’s control panel.

If the motorman falls asleep, although these cases are rare, a vigilance device can detect that.

These devices are installed on every train but may be called differently by other train operators.

The vigilance device is a push button switch that the motorman presses for it to acknowledge his presence.

But as long as the motorman is operating the train, there’s no need to press the vigilance device button from time to time.

The vigilance device button automatically detects if the motorman isn’t honking the horn, applying brakes, or operating any other switch in the control panel.

After one minute of inactivity, it activates and a lamp will light up for the next 8 seconds.

If the motorman does not press the vigilance device button within 8 seconds, then the vigilance device will automatically apply emergency brakes on the train and the train will stop.

The motorman then needs to wait for at least 3 minutes and press the reset push button switch that resets the vigilance device.

Pressing the reset push button switch early will not do anything.

Then this incident will be recorded in the system and the motorman needs to be responsible for it.

But there are still trains with installed dead man’s switch system where the motorman needs to press it while driving the train.

It has the same safety function as the vigilance device; in fact, the dead man’s switch is its predecessor.

The dead man’s switch will detect if the pressure is released therefore its process is activated, and the emergency brakes are applied to the train making the train stop.

Train controls with reset push button switch

14. Is it exhausting for the motorman to constantly push an alarm reset push button switch while driving a train?

Perhaps if the motorman is operating a long-distance train and I would presume that doing this can be mentally and physically exhausting for him.

But there are other factors that the motorman needs to worry about such as checking for dangers in or beside the train tracks, people crossing when the level is closing or already closed, tough weather conditions, and more.

Aside from these external factors, the motorman also bears the responsibility of ensuring his passengers will reach their destinations safely and well.

This means that the lives of his passengers are in his hands.

So constantly pressing the alarm reset push button switch is the least of his worries compared to the weight of his responsibilities as a motorman.

Train motorman and train control panel

15. How does the reset push button switch work on computers?

A computer’s reset push button switch is a normally open momentary push button switch that is installed on a computer.

When the reset push button switch is pressed, the ground on the motherboard is connected to the reset input.

Then once you release it, the entire motherboard resets including all the other devices or plug-in cards connected to it.

This occurrence can be comparable to what happens when you turn on the power button of the computer.

But other plug-in board devices operate a power-on a bit differently from a reset push button switch.

During the power-on occurrence, everything is started up and initialized.

While during a reset, some parts are not re-initialized.

It is highly suggested that the reset button should always be your last resort usually for fixing a computer issue.

Try closing all running applications either by closing them normally or pressing the CTRL-ALT-DEL key combination on your keyboard to open the task manager window and select the applications you need to close.

However, if your screen has frozen, there isn’t much you can do but press the reset push button switch for a few seconds and wait for the computer to restart.

If this frequently happens, it’s best to have your computer checked up by a computer technician.

16. Can you use the reset push button switch as a “kill switch” for your computer?

If you need to protect your computer from unauthorized access, aside from using passwords, you can also wire a secret “kill switch” using the reset push button switch.

Since most of the reset push button switch is a momentary type, you will need to replace it with a maintained type.

So that when you press the reset push button switch, the button is locked in and the CPU will remain in reset mode until you press the reset push button switch again.

If you need to leave your computer, turn it off as you normally would, then press the reset push button switch.

If someone comes along and tries to start the computer, the power light may come on but nothing will happen.

When you need to use the computer again, you just need to press the reset push button switch once again and the computer will turn on as normal.

If you’re worried about what this will do to your computer, it is perfectly okay.

Holding the reset signal will not do any harm to your computer.

17. Can you swap the reset push button switch and the power button on a computer?

Yes, you can do that but swapping them is not necessary.

Perhaps this is only needed when your PC is encountering some issues.

Like when you turn on the power button, the lights on your PC come on but nothing happens.

You may need to open the case and check if the connectors are properly.

If they are okay, then the power button may be broken, you can test it by swapping the connector between the reset push button switch and the power button.

These issues normally happen for cheap built computers, you should expect that the push button switches used are cheap and poor quality as well.

You should consider replacing them with high quality push button switches.

18. Why did they remove the reset push button switch in modern PCs?

Some modern PCs may still have the reset push button switch but most of them may no longer include it.

Manufacturers of computers have removed the reset push button switch simply because it is impractical.

The power button already provides the restart function as well as the shutdown function for the computer.

Therefore, the reset button function has become obsolete.

Example of modern computer

19. Does the washing machine have a reset push button switch?

Some older washing machines have a reset push button switch that resets the machine.

The reset push button switch is usually placed on or at the back of the control panel.

The older washing machines have an overcurrent switch that stops the motor when it is overloaded with laundry and when you press the reset push button switch, the machine will reset and then you can fix the problem.

Modern washing machine already has an incorporated overload inside its motor housing or winding that automatically resets it as the motor cools down.

They already have integrated electronic overload detection hence removing the use of the reset push button switch.

Example of new washing machine model

20.  How to fix a pool pump motor using the manual reset push button switch?

If your pool pump suddenly stopped working, you need to check a few things to identify the problem first.

Check if there’s power being supplied to the pump motor first.

See if there are any blockages in the pump lines that could cause the pump motor to stop.

If there are blockages then clear them up and test the pool pump motor.

If this didn’t work, carefully check the motor if it’s warm or cool to touch.

If it is cool to touch but it won’t start, use a rubber mallet and hit the sides of the motor until it runs.

But if this doesn’t work, check if your pump motor is a manual reset push button switch.

Press it and see if the pump motor will finally run.

If all of these troubleshooting steps failed, and you smell something is burned then the pump motor might be burned and needs replacement.

21. What do you look for to ensure that the reset push button switch is high quality?

When shopping for a reset push button switch, there are several ways to make sure that you can validate if the reset push button switch is high quality.

1. Look for a trusted and a reliable manufacturer

If you are not familiar with reset push button switch manufacturers, one way to know more about them by going to the manufacturer’s website.

Check their company history if they have many years of making reset push button switches in the industry.

Having a long history of manufacturing reset push button switches also means that the company has undergone many certifications to maintain the quality of its products.

2. High customer ratings

By checking the customer ratings or reviews online you can get a good idea about the quality of the reset push button switch.

If the reset push button switch has plenty of negative reviews, then it may not be a smart decision to still purchase the reset push button switch.

But if you see that it has plenty of good reviews and is highly rated by other customers, then the reset push button switch is most likely high quality.

3. Fairly priced

As a consumer, sometimes to save money, you are inclined to choose a reset push button switch that is more affordable or cheaper.

However, the risk involved in choosing a cheap reset push button switch is many such as the possibility that it may not work at all or has a short service life.

So when you are shopping for the reset push button switch, check the prices of your top choices.

See where their prices fall within a price range and determine the average.

You will know what reset push button switches are expensive and which ones are fairly priced.

Bear in mind that some reset push button switches are priced a bit higher when compared with other reset push button switches perhaps due to the benefits that they offer such as being water resistant or anti vandal.

4. View the photos

If you’re shopping for reset push button switches online, you will find at least a couple of its photos included in their product listings.

Check out the reset push button switch photos, enlarge them if you can, and visually inspect them including their appearance or its parts.

Sometimes, you will notice that the reset push button switch is not high quality because of how it looks in the picture.

There could be a video that you can watch that shows more about the features of the reset push button switch.

If you are not satisfied with what you see, you can look for another option.

5. Check the certifications and quality seals

Perhaps one thing that most consumers overlook is the certifications and quality seals of the reset push button switch.

They serve as proof that the reset push button switch has been certified safe for human use and that it is high quality.

Some of the quality seals and certifications you should look for are ISO certified seal, TUV, RoHS compliance seal, REACH, UL seal as well as IP and IK rating seals.

International quality seals

22. Are all kinds of reset push button switches tough for frequent use?

No, not every kind of reset push button switch can endure frequent use or tough for possible abuse.

You will need to look for a specific mark or seal which is placed either in the packaging or on its product listing website.

This seal is the IK10 that indicates a high level of protection against frequent use or abuse.

The reset push button switch with this seal can withstand an impact of up to 5 kg mass dropped from 400 mm above the surface.

The manufacturer has subjected their reset push button switches to a couple of tests namely the Charpy Impact and the Weight Drop tests.

These tests include a series of impact tests conducted to the reset push button switches while being exposed to extreme temperature levels.

The reset push button switch is given the equivalent seal if they pass a certain impact test level.

The IK rating has levels indicated by its number which is from 1 to 10, where 10 is the highest level.

IK rating chart

23. Are all reset push button switches water resistant?

Unfortunately, not all reset push button switches are water resistant.

You need to look for a certain mark or seal on the packaging or in its product listing description to ensure that the reset push button switch is water resistant indeed.

The reset push button switch needs to have the IP rating seal of at least IP65 and above.

If the IP rating seal is higher, the more protection it has against water ingress.

Hence, the reset push button switch is water resistant.

And if you need a waterproof reset push button switch look for IP67, IP68, and IP69K which is the highest rating.

These high IP rating seals indicate that the reset push button switch can be submerged in water for 30 minutes or more and in water depths of 1 up to 3 meters.

The IP rating also indicates protection against solid objects or dust particles.

This means that the reset push button switch can be used outdoors since it has protection against solid particles or water ingress.

IP69K Sealing test

24. How many years of product warranty do manufacturers of reset push button switches provide?

The number of years covered by the product warranty depends on the manufacturer.

Typically, the product warranty coverage lasts for 1 year but some manufacturers offer longer warranty periods of up to 5 years.

If you received a faulty reset push button switch, you should immediately engage with your manufacturer and discuss the issue.

They will advise you about the warranty of the product and let you know what to do next.

You may be required to return the faulty reset push button switch to the manufacturer at your own expense.

Once the reset push button switch is received by the manufacturer, they will inspect it and decide whether the reset push button switch needs to be repaired or replaced.

After the reset push button switch is repaired or replaced, it will be shipped back to your provided address.

The time it takes to repair or replace your reset push button switch usually depends on the shipping period.

If you are far from the manufacturer, except that the repair or replacement of your reset push button switch will take a few weeks.

In general, the product warranty covers issues like this and you’re not required to pay for anything.

But if the reset push button switch was damaged due to human error, you may be billed for the repair fee or the replacement.

25. Do manufacturers accept customization requests for the reset push button switch?

Yes, some manufacturers are happy to accept your customization requests.

They understand that sometimes their customers need to have a specific reset push button switch which is not available in the market.

You may request customization when it comes to the reset push button switch’s size, shape, color, and so on.

You can also request a specific logo or symbol on the reset push button switch if you would like to.
