In what fields can small micro switches be used?
Although micro switches are small, they play an irreplaceable role in our daily lives, realizing automatic control and safety protection in equipment that needs to frequently switch circuits.
At present, it has been widely used in electronic equipment, instrumentation, mining, power systems, household appliances, as well as military fields such as aerospace, aviation, missiles, tanks, etc. In addition, they can also be used in computer mice, car mice, automotive electronic products, communication equipment, military products, as well as test instruments, gas water heaters, gas stoves, small appliances, microwave ovens, rice cookers, floating equipment, medical equipment, building automation, power tools and general electrical and radio equipment, 24-hour timers.
Micro switches are a kind of pressure-activated fast switch, also called sensitive switches. Its working principle is that the external mechanical force acts on the action reed through the transmission element (pin, button, lever, roller, etc.), and after the energy is accumulated to the critical point, an instantaneous action is generated, so that the moving contact at the end of the action reed is quickly connected or disconnected with the fixed contact. When the force on the transmission element is removed, the action reed generates 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 completed instantly.
The contact spacing of the micro switch is small, the action stroke is short, the pressing force is small, and the on-off is fast. The action speed of its moving contact has nothing to do with the action speed of the transmission element. The micro switch is based on the pin type, which can be derived into a button short stroke type, a button large stroke type, a button extra-large stroke type, a roller button type, a reed roller type, a lever roller type, a short arm type, a long arm type, etc.
Micro switches are used in electronic equipment and other equipment for automatic control and safety protection devices that require frequent circuit switching. Micro switches are divided into large, medium and small types. According to different needs, they can be divided into waterproof type (used in liquid environment) and ordinary type. The switch connects two circuits to provide on-off control for electrical appliances, machines, etc.
