What are the classifications of Micro Switch?
There are many kinds of micro switches, with hundreds of internal structures. According to volume integration, there are ordinary type, small type and ultra small type. According to the protection performance, there are waterproof, dustproof and explosion-proof types. According to the breaking form, there are single connection type, double connection type and multi connection type.
There is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also disconnect the switch). According to breaking capacity, there are ordinary type, DC type, micro current type and high current type.
According to the service environment, there are ordinary type, high temperature resistant type (250 ℃) and ultra high temperature resistant ceramic type (400 ℃)
Micro switch generally takes no auxiliary press accessories as the basic type, and derives small line program and large line program. Different auxiliary pressing accessories can be added as required. According to the different pressing accessories added, the switch can be divided into button type, reed roller type, lever roller type, short boom type, long boom type and other forms.
In size, there are small Arm Lever Limit Switches, super small electrical micro switches, super small and so on. The function is waterproof. The most common application is the mouse button.
(1) Small microswitch:
The general size is 27.8 long, 10.3 wide and 15.9 high. In terms of parameters, there are different changes such as high capacity and low load.
(2) Subminiature microswitch
The general size is 19.8 long, 6.4 wide and 10.2 high. It has different functions of high precision and high life.
(3) Super miniature microswitch
The general size is 12.8 long, 5.8 wide and 6.5 high. This type has an extra thin design.
(4) Waterproof Mini Micro Limit Switch type
Where are micro switches used?
Microswitches perform automatic control and safety protection in equipment requiring frequent circuit replacement. They are widely used in electronic equipment, instruments and meters, mines, power systems, household appliances, electrical equipment, aerospace, aviation, ships, missiles, tanks and other military fields. They have been widely used in the above fields. Although the switch is small, it plays an irreplaceable role.
At present, according to different application requirements, the mechanical life of microswitches on the domestic market ranges from 3W times to 1000W times, generally 10W, 20W, 50W, 100W times, 300W times, 500W times and 800W times. Beryllium bronze, tin bronze and stainless steel wire are generally used as springs in China. Alps abroad can achieve 1000W times at most. Their springs are made of rare metal titanium.
It can be used in computer mouse, automobile mouse, automobile electronic products, communication equipment, military products, test instruments, gas water heaters, gas stoves, small household appliances, microwave ovens, electric rice cookers, floating ball equipment, medical instruments, building automation, electric tools, general electrical and radio equipment, 24-hour timers, etc.
