There are many kinds of micro switch, there are hundreds of internal structure, according to the volume of the ordinary type, small, ultra-small;According to the protection performance, waterproof type, dustproof type, explosion-proof type;According to the form of points, there are single - type, double - type, multi - type.There is a strong break microswitch (when the switch's reed does not work, external forces can also break the switch);According to the breaking capacity, there are ordinary type, DC type, micro current type, 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 - switch generally with no auxiliary press accessories as the basic type, and derived from small stroke type, large stroke type.According to the need to add different auxiliary pressing parts, according to the different pressing parts of the switch can be divided into button type, reed roller type, lever roller type, short arm type, long arm type and other forms.
Micro switch in frequent exchange circuit device for automatic control and safety protection etc., are widely used in electronic equipment, instrument and meter, mine, electric power system, household electrical appliances, electrical equipment, as well as aerospace, aviation, warships, missiles, tanks and other military areas, has been widely used in the above areas, switch are small, but plays an irreplaceable role.
The current domestic market of micro switch according to different application requirements, the switch of mechanical life with 3 w to 1000 w, generally speaking, there are 10 w, 20 w, 50 w, 100 w, 300 w, 500 w, 800 w, the domestic general use beryllium bronze, tin bronze, stainless steel wire do reed, foreign ALPS highest can do 1000 w times, their reed is made of rare metal titanium.Domestic Tengfei Electronics production of WK-01B can also reach the highest 1000W.
