How Is A Micro Switch Used?

A micro switch, or a miniature snap-action switch, is an electronic device used to make or break the flow of electric currents. A micro switch typically contains an actuating plunger that travels a short distance to trigger the contact sequence. In order for this to happen, the actuating plunger must be pushed a predetermined amount before it activates. After the actuator is released, the switch will return to its original state.
