[0002] Switchgear refers to the switch in low-voltage electrical appliances that is used to manually connect and disconnect circuits infrequently, or as the switch for introducing power in machine tool circuits. It is divided into knife switches, combination switches, etc., and is used in electrical control equipment of industrial and mining enterprises. In the electrical control equipment of industrial and mining enterprises, low-voltage electrical appliances are basically used. Therefore, low-voltage electrical appliances are the basic components of electrical control, and the quality of the control system is directly related to the performance of low-voltage electrical appliances.

In addition, the existing electrical switch screws lack a good overall structural design. When the overall installation is actually carried out, the tightened screws will loosen, and the anti-loosening effect of the screws is poor.
