Isolating switch with low-current breaking capability

The invention relates to an isolating switch with low-current breaking capacity, which comprises a shell, a movable insulator and a static insulator are mounted on the shell, a movable contact and a static contact are arranged in the shell, the movable contact is mounted at one end of a movable contact seat, the movable contact seat is connected with the movable insulator through a movable conductor, the static contact is connected with the static insulator through a static conductor, and the static insulator is connected with the movable insulator through a static conductor. A static contact is arranged in the shell, an isolation main contact and an inner arc contact higher than the isolation main contact are arranged in the static contact, a nozzle is arranged on the surface of the static contact, cylinders are arranged on two sides of the nozzle, and an SF6 gas chamber is arranged in the shell and is filled with SF6 gas. The invention has the beneficial effects that the capacity of disconnecting the high c
