Many species of micro-switch, there are hundreds of internal structure, according to the volume fraction of ordinary type, small, ultra-small; press protection performance points, there are waterproof, dust-proof, explosion-proof type; by breaking in the form of points, single-joint type, double-type, multi-connection type. There is a strong disconnect the micro switch (when the reed switch does not work when an external force also enables switch off); by breaking capacity points, a common type, DC-based, micro-current, large current type. By use of the environment, a common type, high temperature type (250 ℃), ultra-high temperature ceramic (400 ℃)
Micro Switch generally without auxiliary pressing annex to the basic types, and derive a small line program, accusing him of the program. According to the pressing need to add different auxiliary accessories, according to join different presses accessories can be divided into push-button switch, reed roller, roller lever in various forms, short boom type, long boom type and so on.
Micro switch for automatic control and safety protection in the frequent need for access circuit devices, widely used in electronic equipment, instruments, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, Tanks and other military fields has been widely used over the field, the switch is small, but plays an irreplaceable role.
The current domestic market micro switch according to different requirements, switch mechanical life has 3W to 1000W times per second, generally 10W, 20W, 50W, 100W sub, 300W sub, 500W sub, 800W times, domestic general use beryllium copper, bronze, stainless steel wire as the reed, the highest foreign ALPS 1000W can be done once, their reed is made of rare metal titanium.
