1. What is the momentary push button switch?

Momentary push button switches

The momentary push button switch is a type of push button switch that if you press its actuator, springs back to its default state.

As its name implies, the actuator of the momentary push button switch does not stay depressed after you press it hence the term “momentary” is used.

It is also known as momentary button switch, momentary action switch, momentary contact push button, momentary contact push button switch, momentary electrical switch.

There are many configurations of the momentary push button switch such as different colors, sizes, shapes, and so on.

The momentary push button switches can be found in our homes, such as doorbells, intercom, window blinds controls, and even household appliances such as food processors, blenders, and many more.

2. What are the parts making up the momentary push button switch and how do they work?

The momentary mount push button switch has two main sections which are the head and its body.

The head contains the actuator while the body has several parts and sections such as the threaded neck, the base, and the pins.

Here are the parts making up the momentary mount push button switch including the other parts that you should also know:

1. Actuator
   • This is also known as the head of the switch where the button is positioned at.
   • It has a wide variety of colors, shapes, sizes, and designs such as symbols and logos.
   • It is a movable mechanism that can be pressed down or touched for the touch-sensor or momentary pulse switch types to actuate the momentary push button switch and trigger the function assigned to it such as switching on the momentary light switch or switching them off.
2. Illumination
   • This feature is found in the lighted momentary push button switch with LED, as the LED is the one responsible for its illumination since it is the cheapest among the other alternatives.
   • The majority of the illuminated momentary mount push button switch has an LED chip that illuminates when the button is pressed or it stays lit even when not pressed depending on how you wired it.
3. Body
   • This is also known as the shell or the enclosure.
   • This is usually made up of stainless steel, aluminum, brass, or plastic material.
   • This houses the internal parts of the momentary push button switch and keeps all the parts together in one unit.
4. Grooves
   • Also called the threaded neck of the switch where you can see many visible depressions around the body of the momentary push button switch.
   • This is where the mounting flange is fastened to tightly secure the mounting of the momentary push button switch.
5. Pins
   • These are the protruding metal rods which are also commonly known as the terminals.
   • This is where the wires are either soldered to or clamped connecting the momentary push button switch to its power supply and to the device it is assigned to control.
   • For example, 4 pin momentary push button switch.
6. Mounting flange
   • Along with your momentary push button switch order, you will receive a hex shaped nut that is a separate part
   • This is used to fasten the momentary push button switch at the back of the panel through its rear side or on the front of the panel for the front panel momentary push button switch.
7. O-Ring
   • This is also known as the rubber seal that is placed under the actuator before inserting the momentary push button switch through the mounting hole.
   • This can help seal the gap between the momentary push button switch and the mounting hole to avoid water from entering.
8. Stationary and moving contacts
   • Made up of conductive material positioned beneath the actuator and attached to the terminals.
   • By pressing the actuator the stationary and moving contacts are connected hence they bridge the current to flow from the power source to the device and power the device to operate.
   • If it’s a push to break momentary push button switch, the contacts are already connected by default, and pressing the actuator breaks the current flow hence stopping the operation.
9. Coil Spring
   • The spiral object that stores mechanical energy also called spring steel.
   • For the momentary push button switch, when you press the actuator, the coil spring compresses pushing the moving contacts and touching the stationary contacts hence allowing the current to flow.
   • When you release the actuator, the coil spring bounces back to its original position.

While for latching push button switch, if you push the actuator, it reaches a point where a locking mechanism stops it from springing back and it will only return to its default state when the actuator is pressed once again releasing it from the locking mechanism.

5. What is the difference between the maintained push button switch and the momentary push button switch?

As mentioned earlier, the momentary push button switch does not stay depressed when you press its actuator rather it returns to the default state almost immediately after releasing it.

On the other hand, the maintained push button switch, also called the latching push button switch, remains depressed after pressing the actuator and will only return to its default state when you press the actuator once again.

Both momentary and latching switch actions have their most suitable applications, for example, you will need a latching push button switch for loading equipment while a momentary push button switch can be used for doorbells, small appliances, and so on.

Unfortunately, there’s no momentary latching switch type since these actions are different from each other.

The latching push button switch is also called as the non momentary push button or non momentary push button switch.

9. What materials are used to build the momentary push button switch?

The majority of the momentary push button switches that you can find in the market are made from stainless steel.

This is because of its several characteristics that have been proven efficient and suitable for the functions and applications of the push button switches.

However, stainless steel has many types categorized into grades where each grade has different compositions and in different levels or amounts as well.

These stainless steel grades are designated by the Society of Automotive Engineers hence the grades are named after them for example, SAE 304 whereas the numbers that follow the term represent the chemical compositions.

The stainless steel can include some levels of aluminum, copper, brass, silver, polycarbonate, silicone, ceramic, and many more.

Some amounts of titanium, chromium, molybdenum, nickel, or carbon are also included to make the stainless steel.

These materials can also change the appearance of the stainless steel and more importantly its performance which can either make it more durable and rust proof.

Most manufacturers of the heavy duty momentary push button switches use only two grades of stainless steel and they are the following:

• SAE 304
  • The majority of the manufacturer’s use this stainless steel grade since it is known to be tough against heat and corrosion which protects the momentary push button switches.

18. What is the function of the momentary push button switch on a CPU?

The CPU or system unit uses a reset button for it to be turned on.

The reset button is a normally open momentary push button switch and when it is pressed, it connects the reset input to the motherboard’s ground.

When the reset momentary push button switch is released, there’s an open value that presents a logical “1” which means to “do not reset”.

Then the reset momentary push button switch ignores the switch’s bounce and goes into a conditioned input which forces the entire motherboard circuit to reset that includes the system unit and other relative devices.

The reset momentary push button switch works similarly to the power-on momentary push button switch which provides the initial power to the computer.

But other devices function a bit differently from a reset momentary push button switch when compared to the power-on momentary push button switch.

When you press the power-on momentary push button switch, everything is initialized.

Some system units work well when you do a power-on momentary push button switch.

Although, the reset momentary push button switch is a convenient way to reset the system unit; it is still advised that you use this as your last resort.

If your system unit has frozen, wait for a few minutes and if it doesn’t return to the working mode you can try the CTRL-ALT-DEL way which should open the Task Manager.

Then end any process that is causing the system unit to freeze.

If this does not work, then the reset momentary push button switch applies.

Press the reset momentary push button switch for about 4 seconds or longer until the system unit turns off and restarts.

However, when you do not encounter this issue, there’s the proper way to restart your computer.

Close all the running applications and select the restart option via the window icon on the lower left corner of your screen.

21. How do I make a circuit that when a momentary push button is pressed it charges a capacitor lighting an LED then when let go it slowly dims the LED?

What you will need in this project are the following:

• One 1N4000 series diode
• 1 normally open momentary push button switch
• 1 resistor (390 Ohms and 1/2 watt)
• 1 red 50mA LED
• 1 16V electrolytic capacitor (1000UF to 5000UF in value)
• 9V battery
• 1 battery clip

And here are the steps to follow:

1. Take the red wire and connect the 9v battery clip to the momentary push button switch.
2. Another wire from the other terminal of the momentary push button switch to the diode’s anode.
3. Then another wire the diode’s cathode to connect to the positive end of the capacitor.
4. Then wire the negative end of the capacitor to the battery clip’s black wire.
5. Press the momentary push button switch to charge up to about 9 volts.
6. Wire the resistor to the positive end of the capacitor.
7. Then wire the other end of the resistor to the LED’s anode.
8. Wire the LED’s cathode to the negative end of the capacitor.

The resistor’s value can increase up to 2000 Ohms or more and the LED will get dimmer while the resistor’s value increases but the LED will stay lit as long as it draws a low current from the capacitor.

Avoid using less than 180 Ohms resistor value as this can cause the LED to draw more current than what it is rated for and may not stay lit for long.

You may also opt to increase the capacitor’s value but try to avoid setting it up to 5000 UF as it can generate sparks inside the momentary push button switch that can eventually damage it permanently.

The following are some common problems and the quick fixes recommended for them:

1. Wrong size
   • Sometimes people purchase the wrong size when choosing a momentary push button switch which becomes a problem when you mount it to the equipment with a fixed hole.
   • If the momentary push button switch is too small for the mounting hole, you can try to use the rubber seal that comes with the package to cover the gap or you can also use a label plate that can fill the gap and display a label at the same time.
   • If the momentary push button switch is too big for the mounting hole, you can widen the hole using a steel file until there’s enough clearance for the switch to fit through
2. Melted terminals
   • This generally happens with your solder the terminals for too long or the heat of the solder is too high for them.
   • Start with setting the soldering station to 370°C first and when you solder, target the tip of the terminals to avoid touching the plastic material and solder the terminals within two to three seconds.
3. Loose fitting
   • The momentary push button switch’s mounting flange may have loosened up, or the hole was damaged, or the plastic enclosure became brittle causing it to fall off.
   • Inspect if the momentary push button switch is still good enough to be used or it’s best to have it replaced.
   • Create a new mounting hole if it’s the cause of the problem.
4. Warm switch with a burnt smell
   • If the momentary push button switch feels hot and gives off a burnt smell, it may be drawing a higher voltage than its recommended voltage use causing the internal parts to burn.
   • Turn of the switch, unmount it and check its voltage rating which can look like the following:
     1. 10 amp momentary push button switch
     2. 12v momentary switch waterproof
     3. 15 amp momentary push button switch
     4. 20 amp momentary push button switch
     5. 30 amp momentary push button switch
     6. 12 volt momentary push button switch
     7. 24v momentary push button switch
     8. 110v momentary push button switch
     9. 120 volt momentary push button switch
     10. 120v momentary push button switch
     11. 220v momentary switch
     12. 240v momentary push button switch
   • You can also check it in the packaging of the momentary push button switch or the paperwork that came with it.

28. How can you confirm if the momentary push button switch is strong enough to handle regular use?

If you want to confirm that the momentary push button switch is strong to endure regular use, check if it has an IK10 seal.

The IK rating test is provided to electrical or electronic devices such as the push button switches to determine the enclosure’s strength and the switches’ performance after the tests.

The IK10 seal is the highest level of defense that the momentary push button switch’s enclosure can offer.

This also means that it can be used in applications where it will be used regularly or where it will be located such as public places and establishments.

Yes, you can but not just any momentary push button switch type, you will need a water resistant or water proof momentary push button switch.

If you are going to use the momentary push button switch in a near water environment or areas such as outdoors where it is prone to get wet from the rain, you need a water resistant momentary push button switch.

While applications where the switch can be submerged into water, a waterproof momentary push button switch is best recommended.

These water resistant and water proof momentary push button switches are specially designed to be sealed to protect themselves from water entry.

For you to easily find these types of momentary push button switches, you simply have to look for the IP rating from IP65 and up.

For example, it can be labeled as push button ip67.

These IP ratings proves that the momentary push button switches are water resistant or water proof.

Because for the manufacturers to acquire this rating, they need to have their momentary push button switches undergo certain water tests to determine if they are sealed enough against any water intrusion.

It is also the same rating that is used to determine the protection of the momentary push button switch against solid particle entry.

You can easily see these ratings in the product listing’s title, product description, or on its packaging.
