How does a Micro Switch Work?
The operation of a micro-switch is characterized by the fact that a very small force and a very small actuator movement are typically involved. Most use a stiff metal actuator strip supported by a spring which flips when a certain force on the switch button is applied. When released it flips back with a high speed using hysteresis so the activation force is higher than the deactivation force. The quick movement of the metal strip produces the characteristic clicking sound lending tactile feedback to the mechanism.
