Claims

[Scope of utility model registration request]

An operating arm that rotates in response to excitation control of an electromagnet, an operating rod that is connected to a movable contact placed opposite to a fixed contact in the vacuum valve and that engages one end of the operating arm, and the other end of the operating arm. In a vacuum switch equipped with a pressing spring that is engaged and has a biasing force in the direction of the opening force of the contact, when a vacuum leak occurs in the vacuum valve, the operating arm that is rotated by the biasing force of the pressing spring comes into contact with the vacuum switch. A vacuum switch characterized in that it is equipped with a detection means for detecting a vacuum leak.
