What's the performance of metal key switch? Today I'll give you a detailed introduction. The details are below.
So what is the performance of metal key switches that we need to understand?
Metal key switch with lamp:
1. Metal button switch with lamp, in which the function of lamp is only for indication, is an additional function besides the function of switch itself. Therefore, there is no influence on the function of the switch itself with or without light.
2. The main influencing factors of metal button switch with lamp are the material of shrapnel, terminal, surface treatment of shrapnel terminal (silver plating, tin plating, etc.). In addition, the design of the important dimensions of the switch components also has a great impact, including the service life of the switch, the handle of the operation, the stability of the on-off and on-off, and so on.
3. Metal key switch is a high voltage switch used to cut off and turn on control circuit. The additional current of the contact of the metal button switch is 5A. Therefore, the circuit controlled by the operation button switch belongs to the small current circuit.
4. The switching current and voltage of metal keys vary from 1A to 30A, and the service life varies from 10,000 to 50,000 times. Special requirements can be designed and produced according to customer requirements.
