Microswitches

Microswitches, also known as snap-action switches, are mechanically operated electrical switches consisting of a spring-loaded actuator that opens and closes a set of terminals - common, normally open and normally closed, and they require very little effort to actuate.

Microswitches are reliable and inexpensive and are differentiated by their electrical characteristics, being small in structure they are typically designed to carry only a low current and voltage. Microswitches are often found being utilised within safety processes, preventing a machine from being operated or monitoring the activity of a safety door or guard. Microswitches, much like their larger brother the limit switch, are actuated by a plunger, button a roller or a lever.

Microswitches are utilised in a wide variety of consumer and industrial equipment such as a safety interlock or within washing machine doors. Microswitches can also be found in vending machines as a levelling device or in lift doors where they operate as a safety switch monitoring their position. Some Microswitches can be very sensitive, lending themselves to being used in very precise equipment such as measuring the flow of gas through a system.
