The working principle of the micro switch is: the external mechanical force acts on the action reed through the transmission component (by pin, button, lever, roller, etc.), and when the action reed is displaced to the critical point, an instantaneous action is generated, so that the end of the action reed The moving contact and the fixed contact are quickly turned on or off. When the force on the transmission component is removed, the action reed generates a reverse action force, and 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 micro switch has a small contact pitch, a short stroke, a small power, and a fast switching. The speed of the moving contact is independent of the speed of the transmission element.

There are many types of micro-switches, and there are hundreds of kinds of internal structures. They are divided into ordinary type, small size and ultra-small according to the volume. According to the protective performance, there are waterproof type, dustproof type and explosion-proof type. There are single type, double type, and multiple type. There is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also make the switch open); according to the breaking capacity, there are common type, DC type, micro current type, high current type .

Micro switch is generally based on the non-assisted press attachment as the basic type, and derived a small stroke type, large stroke type. Different auxiliary pressing accessories can be added as needed. According to different pressing accessories, the button can be divided into button type, reed roller type, lever roller type, short moving arm type and long moving arm type.

Micro-switches are widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, etc. in automatic switching and safety protection. In the military field such as tanks, Wuxi Innovation Switching Electric Co., Ltd. has been widely used in the above fields. Although the switch is small, it plays an irreplaceable role.
