What is the use of a micro switch? The external mechanical force acts on the action reed through the transmission elements (press pins, buttons, levers, rollers, etc.). When the action reed moves to a critical point, an instantaneous action is generated, so that the moving contact at the end of the action reed is in contact with the fixed contact. The point is quickly turned on or off; when the force on the transmission element is removed, the action reed produces a reverse action force, when the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is instantaneously completed; The contact distance of the movable switch is small, the action stroke is short, the pressing force is small, and the on-off is rapid. The movement speed of the moving contact has nothing to do with the movement speed of the transmission element.
Mainly used on the switches of some original electrical appliances, such as computer mice, car mice, automotive electronic products, communication equipment, military products, test instruments, gas water heaters, gas stoves, small household appliances, microwave ovens, rice cookers, floating ball equipment, Medical equipment, building automation, power tools, general electrical and radio equipment, 24-hour timers, etc.
The basic type of micro switch is generally without auxiliary pressing attachment, and derives small stroke type and large stroke type. Different auxiliary pressing accessories can be added according to the needs. According to the different pressing accessories added, the switch can be divided into various forms such as button type, reed roller type, lever roller type, short boom type, long boom type, etc.
At present, the micro switch on the domestic market varies from 3W times to 1000W times depending on the use requirements. Generally, there are 10W, 20W, 50W, 100W times, 300W times, 500W times, and 800W times, and they are generally used in China. Beryllium bronze, tin bronze, and stainless steel wire make reeds. Foreign ALPS can achieve up to 1000W times. Their reeds are made of rare metal titanium. The WK-01B produced by domestic Ascendas Electronics can reach up to 1000W times.
