What is a microswitch?

A microswitch, also called a limit switch or snap action switch, is a type of highly sensitive, small switch that is usually activated by mechanical means. It gets its snap-action name from the spring-loaded internal mechanism, which snaps between two positions when triggered. This switching mechanism is typically enclosed, with only a small button protruding from the casing. 

Often a long thin metal arm or actuator protrudes over the switch, acting as additional leverage. A roller might be mounted at the end of this metal arm so the switch can be activated when it slides against a moving mechanical component. 

These switches are usually SPDT and function in ON-(ON) mode and sometimes OFF-(ON) or (rarely) ON-(OFF).
