What is a microswitch?

A micro switch is an electrical switch which can be operated using a very small force and also possibly using a small movement.

How does a microswitche work?

Micro switches work differently. The most comman types use a stiff metal strip supported by a spring which suddenly flips when a certain force on the switch button is applied. It flips back with a high speed too when the force decreases under certain limit. The switches use hysteresis so the activation force is higher than the deactivation force. Also the quick moving of the metal strip produces the typical clicking sound (known for example from computer mouse buttons).
