1. What are the push button toggle switch and its known function?

Push button toggle switches

According to history, the push button toggle switch is a variant of the toggle switch among several others.

It is also known as a simple “on” and “off” switch and can be called with other terms such as push in button, push button as toggle switch, toggle push button, toggle push button switch, toggle push switch, push toggle switch, toggle switch push button, or push button on switch.

If the toggle switch is operated using a lever, the push button toggle switch uses a push button mechanism to actuate the switch.

By definition, the word “toggle” means that it is a key or command that can alternatively execute two opposite functions consecutively.

This definition is also relatively true when it comes to push button toggle switches since they can control two different switch actions, the “on” and “off” states.

If the toggle is flipped up or down to actuate the switch action, the push button toggle switch is pressed down to turn the switch “on” and pressed again to turn it “off”.

To further understand how this works, let’s take the light switch for example, a common application of the push button toggle switch.

Let’s say that the light switch is connected to the push button toggle switch.

Initially, the push button toggle switch is in its “off” state.

If it is with LED, like a led light toggle switch, you can wire it to light up only when it is pressed.

When you need to turn the lights on, you press the push button toggle switch, its LED will glow, and the lights will be on.

Now, if you would like to turn the lights off again, you simply press the push button toggle switch, its LED will stop glowing, and the lights will be off.

And if you wire the push button toggle switch to have the LED be always “on”, whether you press the actuator or not, the LED will remain glowing which makes it easier to find the light switches even in the dark.

Fun Fact: The push button toggle switch has been around for more than a century now.

In 1916, William J. Newton first invented the “toggle light switch”.

This light switch is the second light switch technology succeeding the quick break switch technology which was invented by John H. Holmes in 1884.

Not long after, a variation of the push button light switch was invented.

This push button light switch features two push button switches, one that opens the contacts and the other one that closes it.

One push button is raised while the other one is depressed, when you push the raised button, it will pop out or raise the depressed button as if they are exchanging positions.

The process can be reversed alternatively, with each push button performing its specific switch action (on and off).

These light switches are generally black and the “on” push button has a white material usually a mother-of-pearl inlay to indicate its function usually.

Usually, the “on” button is the one located on the top.

These vintage light switches are still manufactured by some manufacturers today if you want a piece of history.

In modern times, these separate push button switches’ function was combined into one, hence the birth of the push button toggle switch.

2. What is the advantage of a push button toggle switch over the toggle switch?

Perhaps the biggest advantage of using the push button toggle switch is that the design prevents inadvertent actuation.

Unlike the toggle switch, where the lever can be easily flipped accidentally causing unnecessary operation, the push button toggle switch requires you to initiate some type of action like pressing the button to actuate the switch.

While you can use flip switch covers to protect the toggle switch and prevent instances of false switching, this could cost more because the flip switch covers are sold separately.

Other notable advantages of the push button toggle switch are the following:

• Easy to operate
• Avoids accidental actuation
• Offers two switch action in one unit
• Have more surface clearance
• Attractive aesthetics
• Provides a modern look and feel
• Features better designs
• More varieties to choose from
• Affordable and cost-effective
• Durable and hard-wearing

There could be more advantages of the push button toggle switches that you can experience once you have been using them on your applications.

And so much more…

Applications of the push button toggle switch

5. What is the push button toggle switch contact design?

The push button toggle switch contact design follows a general switch contact design where it is built with any mechanism that controls conductors to contact each other.

For example, by pressing the push button toggle switch’s actuator, the conductive parts inside it come into contact hence making or breaking the current flow.

Typically, these contacts are made from silver or its other type, the silver- cadmium alloy.

However, these contacts may be prone to oxidation or corrosion but do not significantly compromise their conductive properties.

While another type of contact is made from gold which provides the best corrosion resistance when compared to silver.

However, gold contacts have a limited capacity in carrying current and there’s also a possibility that they may “cold weld” if too much force is applied in pressing the actuator.

But whichever metal is used for the contacts, there’s a guiding mechanism that ensures balanced contact action for better push button toggle switch performance.

6. What is the normal contact state of the push button toggle switch?

All kinds of switches, including the push button toggle switch, have a normal contact state.

The normal contact state is the default state of the contacts when there’s no applied force.

In general, the push button toggle switch has two types of normal contact state, it can be normally open or normally closed.

• The normally open push button toggle switch has an open circuit which means that the contacts are not touching each other, therefore; the current is not able to flow.

When you press the actuator of a normally open push button toggle switch, the contacts are brought together, and the current will flow hence actuating the switch.

The normally open push button toggle switch is also known as a “push-to-make” switch or push to close switch.

• The normally closed push button toggle switch has a closed circuit, and this means that the contacts are connected which encourages the current to flow.

When you press the normally open push button toggle switch’s actuator, the contacts break and stop the flow of the current.

This is why the normally closed push button toggle switch is also called the “push-to-break” switch or push to open switch.

These two contact states are represented by two almost similar schematic symbologies.

The normally open push button toggle switch is represented by a symbol that shows an open connection while the normally closed push button toggle switch has a symbol that shows a closed connection.

They also have a generic symbology which is generally used in electrical circuit diagrams.

The normally open push button toggle switch is drawn in such as way that the lines are not touching each other.

While the normally closed push button toggle switch has a diagonal line that bridges the two vertical lines.

7. What kind of switch action does the push button toggle switch have available?

Just like most switches, the push button toggle switch has two different switch actions available.

You may find that manufacturers label their push button toggle switches with their specific switch action.

These are called the momentary push button toggle switch and the latching push button toggle switch.

Here’s a brief explanation of how each of these switch actions works:

The momentary push button toggle switch provides a temporary switch action.

When you press the actuator, the momentary push button toggle switch is actuated, but when you release the actuator, it will spring back to its default position.

Some examples of the momentary push button toggle switch are electronic power buttons, doorbells, buzzers, car horns, and so on.

You can search for push button horn switch, push button cord switch, or non latching toggle switch.

On the other hand, the latching push button toggle switch has a maintained switch action.

If you press its actuator, the button is depressed and will remain that way until you press it again.

Then it will spring back to its original position.

Examples of the latching push button toggle switch are light switches, elevator call buttons, audio controls, and so on.

8. Is the push button toggle switch SPST or SPDT?

As mentioned earlier, the push button toggle switch is a simple “on” and “off” switch or sometimes called a basic on and off switch.

The push button toggle switch, being a basic switch means it also has a simple switch configuration.

It can either be SPST or SPDT.

SPST stands from Single Pole Single Throw while the SPDT means Single Pole Double Throw.

The poles refer to the circuits that can be controlled by the switch; in this case, the push button toggle switch can control a single circuit.

While throws refer to the utmost position of the actuator which means that the push button toggle switch can only have one position, “on” or “off”.

An SPDT push button toggle switch only has one input but it can switch between the two outputs.

Depending on how it was wired, it can serve as an on and off switch.

Below are some varieties of the basic switch action:

• On-Off (SPST)
• On-On, On-Off (SPDT)

9. Why choose a push button toggle switch built with protective features over the standard types?

Since the push button toggle switch can be used in different applications and environment settings, it is necessary to consider opting for those with protective features.

Let’s take for example the anti vandal push button toggle switch.

Because of its tough and durable quality, it can be used in applications where it will be used regularly like those in public places, stores, shopping malls, and so on.

A standard type of push button toggle switch may not last long if given the same condition and environment setting.

It may be good enough to use in a an environment with fewer people, you can never be guaranteed its longevity and performance.

10. Do push button toggle switches go bad quickly?

The answer is yes and no.

Before we expound on that, it is important to note here that high quality push button toggle switches can have over 1 million mechanical life cycles and more than 200,000 electrical life cycles.

The condition of the push button toggle switches is dependent on two major factors that can affect its performance and its service life.

The first factor is the quality of the push button toggle switch.

If you purchase a poor quality push button toggle switch, usually those cheaper alternatives, you can’t expect it to last long.

Even if you rarely use it, it may fail you anytime.

This is a problem if you are using the push button toggle switch for an important purpose such as production machinery, or equipment.

If the push button toggle switch fails, it can cause a delay in production which can also cause a loss of revenue.

The second factor is how the push button toggle switch is used.

The push button toggle switches have specific types that are specially made for certain application conditions.

For example, if you will be using the push button toggle switch in an equipment that will be used quite frequently, it is highly recommended that you use an anti vandal push button toggle switch.

This is because the anti vandal push button toggle switch is manufactured to endure repeated use.

If you will use a regular push button toggle switch, it can be easily damaged because it was not made to be tough and durable.

The other factors that can harm the performance and service life of the push button toggle switches are the following:

• Environment – The push button toggle switch is installed in an environment setting where it is not made for.

For example, installing a regular push button toggle switch outdoors that exposes it to rain and dust but it is not built for it.

In this case, you should use a water resistant push button toggle switch that can withstand weather changes and exposure to dirt and dust.

• Temperature levels – In some applications, the push button toggle switch could be exposed to a high level of temperatures that it is not capable of handling therefore its performance is affected or to make it worse, it may melt or burn.

Refer to the technical data sheet of your push button toggle switch and check the temperature levels recommended by its manufacturer.

If you need a specific push button toggle switch that can handle extreme temperatures, you may consult with the manufacturer to accommodate your needs.

• Surface vibration – Vibrating movement can loosen the internal parts of the push button toggle switch.

In this scenario, it is best recommended to use an anti vandal push button toggle switch that can endure this kind of condition.

• Supplying high current – The push button toggle switch has different types of current ratings.

If you supply a current higher than the voltage capacity of the push button toggle switch, it may feel hot to touch which could indicate that the contacts inside it have burned due to the powerful current supplied rendering it unusable.

Refer to the product listing of the push button toggle switch to know its voltage rating before making a purchase.
