What is the basic form of small micro-switch? The specific form will be introduced in detail below.
There are many kinds of small micro-switch, with hundreds of internal structures, which can be divided into ordinary type, small type and super-small type according to volume, waterproof type, dust-proof type and explosion-proof type according to protective performance, and single-connected type, double-connected type and multi-connected type according to breaking form. 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); according to the breaking capacity, there are ordinary, DC, micro-current and large-current modes. According to the use environment, there are ordinary type, high temperature resistant type (250 C), super high temperature resistant ceramic type (400 C).
Small micro-switch is generally based on no auxiliary press attachment, and derives small and large running 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 3W to 1000W according to different requirements. Generally, there are 10W, 20W, 50W, 100W, 300W, 500W, 800W. In China, 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. The highest number of WK-01B produced by domestic takeoff electronics can reach 1000W.
