Claims

[Claims for Utility Model Registration] (1) A pair of electrodes that can be freely moved into and out of contact with each other is provided in a vacuum container, and the outer end of the fixed electrode rod connected to one of the electrodes is connected to the fixed end plate of the vacuum container. In the vacuum switch tube which penetrates the tube and leads out of the vacuum vessel and connects the outer end of the fixed side electrode rod to the circuit breaker, the fixed side end plate is provided with a locking part for the circuit breaker, and the A vacuum switch characterized in that when a fixed side electrode rod is connected to or separated from the circuit breaker, rotation of the vacuum container is prevented by locking the locking portion to the circuit breaker. tube. (2) The vacuum switch tube according to claim 1, wherein the locking portion is formed by a protrusion provided on the outer surface of the fixed end plate. (3) Claim 1 of the Utility Model Registration Claim characterized in that the locking portion is constituted by a cylindrical protrusion that surrounds the exhaust pipe led out to the outside of the fixed side end plate. vacuum switch tube.
