Abstract

In the switchgear opening/closing device, a movable contact 5 can be switched to the first position Y1, the second position Y2 and the third position Y3 with respect to a fixed contact. The device comprises an operation lever 80 interlocked with the movable contact 5, a shaft 31 to which the base of the operation laver 80 is fixed, a first operation mechanism 40, coupled with the shaft 31, to switch-operate the movable contact 5 to the first position, the second position and the third position, and a second operation mechanism 70 to selectively switch between prevention of movement and movement of the movable contact 5 from the second position to the third position by the first operation mechanism 40.
