Pushbutton Switches are everywhere, like refrigerator doors, gaming consoles, home appliances, industrial panels, etc.
And if you are a knowledge seeker, a company owner, or a wholesaler looking to learn what they are exactly, how they work, their types of switches, and why they are used in place of standard switches, then you have come to the correct spot.
1) What is a Push Button Switch?
“As the name suggests, Pushbutton switches are electrical switches that work by pressing ( pushing ) the button.”
Push switches can be found in various applications like PCs, phones, industrial machines, and appliances. In addition, they are used in gaming consoles like the Xbox and PlayStation.
Push switches can be made of plastic or metal, or both materials. Moreover, they come in various styles, sizes, and colors for multiple needs.
They can have a round, rectangular, or oval shape. The buttons can be flush-mounted or raised. It is common for colors to be black and white, but they can also be green, red, or blue for function differentiation on a single panel which helps quick identification in emergencies.
Based on their function, Push Button Switches can be divided into 2-types;
ⅰ) Momentary Push Button Switches
“For a Momentary Push Button Switch to function, it has to be pushed constantly, and when you release it, it will return to its normal position.”
As the name suggests, the Momentary Push Switch functions only briefly ( when the button is pressed ), making it appropriate for applications such as momentary lighting control like refrigerator door lights, etc. These are also called non-latching push button switches.
Basically, there are 2-kinds of Momentary Push Button Switches;
Push to Make
Push to Break
|“Their electrical circuit is open when not pushed, meaning their current is off. But when you push them, the electrical circuit is connected, and the current starts moving.”
|“When not pushed, their electrical circuit is closed & current is flowing. But when you push them, the electrical circuit breaks, turning off the current.”
|“As they are making a electrical circuit when pressed, that’s why they are called Push to Make switches.”
|“As they break the current flow when pushed, they are named Push to Break.”
|Also known as
|“As these switches are always off in their normal not pushed state due to their open circuits, they are known as Normally Open ( NO ) Switches.”
|“As these switches are always on in their non-pushed state due to their closed circuit, they are also known as Normally Closed ( NC ) Switches.”
➔ Some Famous Examples
Below are some famous examples of Momentary Push Button switches, but they only count as the tip of the ice burg in these switches’ various applications;
● Controlling electric locks or entry systems in security applications.
● Operating garage door openers, allowing temporary and controlled access.
● Triggering a camera shutter for capturing photos in photography or videography.
● Activating voice recording or playback functions in audio devices or communication systems.
● Initiating a call or answering a call in telecommunication devices or hands-free systems.
● The Refrigerator door switch turns on the bulb when the gate is opened and turns it off when you close the door.
● Much more.
“As the name suggests, Latching Push Button Switch, when pressed, maintains its electrical circuit state ( biome latched ), and it will only change its state when the user pushes it again.”
Unlike Momentary switches, they don’t need a constant push to work. For example, a 2-state on/off Latching push switch works in the following way;
➢ When you push it once, it will turn on from its off state, and the circuit will remain on, even when the user removes his hand.
➢ When you push it again, it will change its state from on to off and maintain its condition until it is pressed again.
➔ Some Famous Examples
● Car Engine Start power switch to turn off and on a vehicle.
● Home automation systems for controlling various functions like opening/closing curtains, turning on/off appliances, or adjusting room temperature.
● Control machinery and equipment in industrial settings.
● Audio equipment for toggling between different audio sources or modes.
● Lighting control panels where the user can toggle between different lighting configurations.
● Motor controls in industrial machinery allow operators to set and maintain the desired speed or direction.
● Power switches in electronic devices where the user wants to get specific on/off state until intentionally changed.
|Note “It is important to note that no matter its a momentary or latching push button switch, the button itself will always return to its normal state, irrespective of its electrical circuit state.”
Before understanding how it works, it is best to recognize the components, which are;
● A button, also known as an Actuator.
● A long rod on which the button is fixed.
● A spring in the rod; forces the button to get to its normal state when you stop pushing.
● A metal bar, which is set on another end of the rod.
● There are two separate terminals; one has current, and one doesn’t.
● A plastic/metal casing that encloses all components.
So, when you press a button, a downward force moves the button, the rod attached to it, and finally, the metal bar attached to the rod bottom all move downward. Then next, the work is different;
➢ In Normally Open ( NO ) switches, the terminals are present at the base. So, when the metal bar reaches them, it acts as a bridge between these two separated points and completes the circuit; the current start flowing. And when you release the button, the spring pushes back the rod & the metal bar upward, which breaks the circuit, and the current stop flowing.
➢ In Normmaly Closed ( NC ) Switches: the circuit terminals are at the start of the casing, so when you press the button, the metal moves downward, far from the terminals, which breaks the circuit ( turn it off ). And when you release the button, the spring moves and the metal bar moves upward and completes the circuit again ( current starts flowing ). Only Momentary circuits are common in this setup; latching switches with an NC mechanism are rare.
These have mostly NO mechanism, in which a latch holds a metal bar in its place while the spring pushes the button to its usual place. And when you press the button again, the latch releases the metal bar, which moves upward, breaking the circuit.
There are many kinds of switches worldwide, and everyone has pros and cons. And if you are looking to find out the difference between Push Button Switches & Rocker Switches so you can find the best ones according to your needs, in that case, see the chart below;
