There are many forms of micro-switches. There are hundreds of internal structures. There are primary, mini and sub miniatures in accordance with quantity; in accordance with protection efficiency, there are waterproof type, dustproof sort and explosion-proof sort; based on the kind of breaking, there are Single connection type, double connection kind, a number of connection type. There is also a strong disconnection micro switch (when the reed of the switch doesn't work, the external pressure can even make the switch open); based on the breaking capability, there are odd type, DC sort, microcurrent type, giant present type. According to the use setting, there are odd kind, excessive temperature resistant type (250℃), ultra high temperature resistant ceramic type (400℃)
The micro switch is generally based on the non-auxiliary urgent attachment as the basic sort, and derives a small stroke sort and a big stroke type. Different auxiliary urgent equipment can be added according to needs, and the switches could be divided into various varieties corresponding to button type, reed curler sort, roller lever type, quick lever type, long lever type and so forth based on the completely different urgent accessories added.
Micro switches are used for computerized control and security protection in gear that requires frequent circuit substitute. They are extensively used in electronic tools, instrumentation, mining, energy methods, family home equipment, electrical tools, in addition to aerospace, aviation, ships, missiles, Military fields similar to tanks have been broadly used within the above fields. Although the switch is small, it performs an irreplaceable function.
At current, the micro-switches on the home market differ from 3W times to 1000W occasions in accordance with different necessities, typically 10W, 20W, 50W, 100W instances, 300W instances, 500W times, 800W times, domestic common use Beryllium bronze, tin bronze, and stainless steel wire are used as reeds.
Applications of Micro Switches
The current market of micro switches according to totally different utility necessities, the switch of mechanical life with 3w to 1000 w. Generally talking, there are 10 w, 20 w, 50 w, 100 w, 300 w, 500 w, 800 w, the general use beryllium bronze, tin bronze, stainless steel wire do reed, international ALPS highest can do 1000 w instances, their reed is made of rare metallic titanium.
Micro switch in frequent trade circuit gadget for automated management and safety protection and so on., it’s broadly applicated in electronic gear, instrument and meter, mine, electrical energy system, family electrical home equipment, electrical tools, in addition to aerospace, aviation, warships, missiles, tanks and other military areas, has been extensively used in the above areas, switch are small, but plays an irreplaceable role.
It also can be used in corresponding to computer mouse, automobile mouse, car digital products, communications gear, army product, test instrument, fuel water heater, gasoline burner, small home equipment, microwave oven, electric rice cooker, floating ball supporting tools, medical gear, building automation, electrical instruments and common electrical, and radio equipment, 24 hours timer, and so forth.
