There are many types of micro-switches. There are hundreds of internal structures. There are basic, mini and sub-miniature according to volume; according to protection performance, there are water-proof type, dust-proof type and explosion-proof type; according to the type of breaking, there are Single connection type, double connection type, multiple connection type. There is also a strong disconnection 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 ordinary type, DC type, micro current type, large current type. According to the use environment, there are ordinary type, high temperature resistant type (250℃), ultra high temperature resistant ceramic type (400℃)
The micro switch is generally based on the non-auxiliary pressing attachment as the basic type, and derives a small stroke type and a large stroke type. Different auxiliary pressing accessories can be added according to needs, and the switches can be divided into various forms such as button type, reed roller type, roller lever type, short lever type, long lever type and so on according to the different pressing accessories added.
Micro Switches are used for automatic control and safety protection in equipment that requires frequent circuit replacement. They are widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, military fields such as tanks have been widely used in the above fields. Although the switch is small, it plays an irreplaceable role.
At present, the micro-switches on the domestic market vary from 3W times to 1000W times according to different requirements, generally 10W, 20W, 50W, 100W times, 300W times, 500W times, 800W times, domestic general use Beryllium bronze, tin bronze, and stainless steel wire are used as reeds.
