A push button switch has a simple electric mechanism that can turn the circuit on or off. It can control the action in any machine and is commonly found at home or the workplace. The button is usually made from plastic or metal.
When pressure is applied to the actuator or button, there is depression in the internal spring. Hence, it touches the contacts beneath the switch. It will open or close an electric circuit.

There are various types of push button switches. They include but are not limited to:
Momentary: Users must press down the spring to power the circuit off or on
Two-position: There are two set positions to turn the circuit on or off
Micro: These are used to reset small electronic devices
Push to Break: The electricity flow is stopped when pressing the switch
Push to Make: Electricity flows through the circuit when the contacts are held together by pressing the switch
Locking: A locking function prevents the button from returning to the original position after release
Industrial: These are built-in units used in areas that need manual intervention
Tactile: They are mounted on PCBs and require a small force to turn it on and make a clicking noise to indicate whether it is turned on or off
