Work principle editor External mechanical force through the transmission element (by pins, buttons, levers and rollers etc.) will force on the action of reed, produce instantaneous action when the action spring displacement to the critical point, the action at the end of the reed moving contact and fixed contact quick connect or disconnect. When the force on the transmission element is removed, the action reed has a reverse actuating force, and when the reverse stroke of the drive element reaches the critical point of the reed, the reverse motion is completed at once. The contact distance of inching switch is small, the action stroke is short, the power is small and the on-off is quick. The moving speed of the moving contact is independent of the speed of the drive element. Category editor Type of micro switch internal structure variety, there are hundreds of species according to the integral small ordinary type, small, super; according to the protective properties, waterproofing and dust, explosion-proof type; by breaking the form, a single type, double type, multi type. There is also a strong disconnect micro switch (when the switch reed does not work, the external force can also make the switch off); according to breaking capacity, there are ordinary, DC, micro flow patterns, high current type. According to the use environment, there are ordinary type, high temperature resistant type (250 degrees Celsius), high temperature resistant ceramic type (400 degrees Celsius) The micro switch to press without auxiliary accessories for basic types, and to derive the small program, the program. According to the requirement, different auxiliary press accessories can be added. According to the different pressing auxiliary switches added, the switches can be divided into button type, reed roller type, lever roller type, short movable arm type, long moving arm type and various other forms. The micro switch in need of automatic control and safety protection circuit frequently change equipment, widely used in electronic equipment, instrumentation, mines, electric power system, household appliances, electrical equipment, and aerospace, aviation, ships, missiles, tanks and other military areas, has been widely used in these areas, the switch is small it plays an irreplaceable role. At present, the domestic market for the micro switch according to the requirements of the different mechanical life of the switches are 3
