What Are The Basic Types Of Small Micro-switch
A wide variety of small micro-switch, the internal structure of hundreds of thousands of types, according to the body integral has a common type, small, subminiature; According to the protection performance, there are waterproof type, dustproof type, explosion-proof type, according to the broken form, there is a single, dual-link type, multiple- There is also a strong disconnect micro-switch (when the reed of the switch does not work, the external force can also make the switch disconnected), according to breaking capacity, there are common type, DC type, micro-current type, large current type. According to the use of the environment, there are common type, high temperature resistant type (250 ℃), ultra-high temperature ceramic type (400 ℃)
Small micro-switch is generally no auxiliary pressure attachment as the basic type, and derive small line program, large-line program. According to the need to add different auxiliary compression accessories, according to the addition of different pressing accessories switch can be divided into button type, reed roller type, lever roller type, short moving arm type, long moving arm type and other forms. At present, the domestic market of micro-switch according to the use of different requirements, switch mechanical life of 3W to 1000W times, ranging, generally have 10W, 20W, 50W, 100W times, 300W, 500W, 800W, the domestic general use of beryllium, tin bronze, stainless steel wire reed, foreign Alps can do the highest 1000W times, their reed is made of rare metal titanium.
