Micro switch as one of the basic electronic components of the product, also basically realized nationalized production. Microswitches are widely used in precision manufacturing industries such as medical instruments and aviation equipment, as well as in industries with relatively low technology content such as toy manufacturing.
Microswitches consist of five major components. The contact spacing is smaller and the torque is larger. Generally external drive rod. Micro switch is a small contact interval and fast moving mechanism, with the specified stroke and the specified force of the switch action contact mechanism, covered by the shell, its external drive rod of a switch, because the switch contact spacing is relatively small, so the name of micro switch, also called sensitive switch.
There are many kinds of micro switch, internal structure has hundreds of kinds, according to the volume of ordinary type, small, ultra-small; According to the protection performance, there are waterproof, dustproof, explosion-proof type; According to the breaking form, there are single - link, double - link, multi - link type.
Micro switch in the need to frequently change the circuit of the equipment for automatic control and safety protection, widely used in electronic equipment, instruments, mines, power systems, household appliances, electrical equipment, and aerospace, aviation, ships, missiles, tanks and other military fields, has been widely used in the above fields, the switch is small, but plays an irreplaceable role
