[0002] An isolating switch is a device mainly used to isolate power supply, perform switching operations, and connect and disconnect low current circuits.

[0003] However, when the isolating switch is opened, the staff needs to manually open the switch, which is a cumbersome operation, a large workload for the staff, and is not convenient for rapid opening, and there are certain safety risks when opening the switch.

Although it can improve the convenience of the staff, the staff is also required to manually operate when closing the switch. For this reason, we provide a disconnector that is easy to open to solve the above problems. Utility Model Content
