Micro switch is a kind of pressure actuation fast switch, also called sensitive switch, its working principle is through external mechanical force transmission element (by pin, button, the lever, roller, etc.) will work for action on the reed, and the energy accumulation to the point, produce instantaneous action, make the action at the ends of the reeds moving contact with the contact on or off quickly.
When the force on the transmission element is removed, the action reed produces reverse action force, and when the reverse travel of the transmission element reaches the critical point of the action of the reed, the reverse action is instantaneously completed.
Micro switch contact spacing is small, action stroke is short, according to the power of small, quick on and off. The speed of the moving contact has nothing to do with the speed of the transmission element.
The micro switch is based on the pin type, which can be derived from the button short stroke type, button large stroke type, button extra stroke type, roller button type, reed roller type, lever roller type, short arm type, long arm type and so on.
Micro switch is used in electronic equipment and other equipment for automatic control and safety protection of frequent switch circuit.
Micro switch is divided into large, medium and small, according to different needs can be divided into waterproof type (used in liquid environment) and ordinary type, switch connected to two lines, for electrical appliances, machines and so on to provide power control.
