Structure, Life, Classification & Application of Microswitch
- February 5, 2020
The micro switch
There are many kinds of microswitches. According to body integral, it includes internal structures, common type, small type and ultra small type. According to protection performance, there are waterproof type, dust-proof type and explosion-proof type. According to breaking form, there are single connection type, double connection type and multi connection type . What’s more, a strong disconnect microswitch is also widely used. When the reed of the switch does not work, the external force can also make the switch disconnect. According to the breaking capacity, there are common type, DC type, micro current type and large current type. According to the use environment, there are ordinary type, high temperature resistant type (250 ℃), super high temperature resistant ceramic type (400 ℃). Micro switches are generally based on the type without auxiliary press accessories, and derive small line program and large line program. Different auxiliary press accessories can be added according to the needs. According to the different press accessories, they can be divided into button type, reed roller type, lever roller type, short boom type, long boom type and other forms.
Microswitch is widely used in electronic equipment, instruments and meters, mines, power systems, household appliances, electrical equipment, as well as military fields such as aerospace, aviation, ships, missiles, tanks and so on. Although it is small, it plays an irreplaceable role.
Port source electronics
At present, the mechanical life of microswitch in domestic market varies from 30k times to 10m times. According to the different use requirements, There are generally 100k, 200k, 500k, 100k times, 3m times, 5m times and 8m times. Beryllium bronze, tin bronze and stainless steel wire are generally used as reed in China, while Alps in foreign countries can reach 10m times. Their reed is made of rare metal titanium.
Classification of microswitches
As the name suggests, use a very small force switch. The contact spacing is small and the torque is large. Generally, there is a drive rod on the outside. In terms of size, there are small, super small, super small and so on. The function is waterproof. The most common application is the mouse button.
- Small microswitch:
The general size is 27.8 in length, 10.3 in width and 15.9 in height. In terms of parameters, it has high capacity and low load.
- 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.
- Subminiature microswitch
The general size is 12.8 long, 5.8 wide, 6.5 high. In this type, there is a very thin design.
- waterproof type
The waterproof level of such products has reached IP67.
