What is a push button switch?

Metal push button switches are called push buttons for short, which are usually used to switch on or off the control circuit. It is a low-voltage electrical appliance that gives instructions in electric drag, and also is a master control electrical appliance, which is very widely used. In the electrical automatic control circuit, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc.

When a push button is installed on a working machine or instrument, it is in the original free position most of the time.

The switch is converted to the second state only when required by an external force, and as soon as the external force is removed, the switch returns to its original position because of the spring.
