Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to an electrical switch contact piece. Background Art

[0002] As we all know, electrical switch contacts are a widely used switching device that uses electromagnetic, pneumatic or hydraulic principles to control the circuit to achieve the on and off of the main circuit. Contactors have the advantages of strong current breaking capacity, rapid action, safe operation, frequent operation and remote control, but they cannot cut off short-circuit currents. Therefore, contactors are usually used in conjunction with fuses. The main control object of the contactor is the motor, and it can also be used to control other power loads, such as electric welding machines, electric furnaces, etc. Existing electrical switch contacts are generally equipped with cooling blocks to cool the electrical switch contacts.

[0003] However, the cooling blocks on the existing electrical switch contacts are generally connected by bolts. When the cooling blocks need to be replaced, the bolts need to be unscrewed one by one, which wastes a lot of time. The removed bolts are also prone to being lost. Utility Model Content
