Switches can be regarded as a kind of electronic components that we often deal with. There are also different kinds and brands of switches on the market. These switches bring convenience to our life. Here we talk about the micro-switch. The reason why they are named "micro-switch" is that the contact spacing of the switch is relatively small. Perhaps many people do not know where these switches are used. In fact, the application of micro-switch is very extensive, and it is very close to our life. The micro-switch used in household appliances and mouse are the most frequently contacted ones. It is also widely used in electronic equipment, instruments, mines, power systems, as well as military fields such as aerospace, aviation, ships, missiles and tanks. There are many types of micro-switch. There are hundreds of different types of microswitches. The following are the most common types of microswitches.
1. According to volume, they are ordinary, small and super-small; according to protective performance, they are waterproof, dust-proof and explosion-proof.
2. According to the form of breaking, there are single-connection, double-connection and multi-connection. At present, there is also a kind of micro-switch with strong disconnection (when the spring of the switch does not work, the external force can also make the switch disconnect).
3. According to the breaking capacity, there are common type, DC type, micro-current type and large-current type.
4. According to the use environment, there are ordinary, high temperature resistant and super high temperature resistant ceramics.
Fretting switch is generally based on no auxiliary press attachment, and derives small and large stroke programs. According to the need, different auxiliary pressing accessories can be added. According to the different pressing accessories switch can be divided into button type, reed roller type, lever roller type, short arm type, long arm type and other forms.
At present, the mechanical life of micro-switch in domestic market varies from 2W to 1000W according to different requirements. Generally, there are 10W, 20W, 50W, 100W, 300W, 500W, 800W. In domestic, beryllium bronze, tin bronze and stainless steel wire are commonly used as reeds. Alps in foreign countries can be up to 1000W. Their reeds are made of rare metal titanium.
