Abstract

To provide a switchgear havinghighelectricalisolating performanceinadditiontocapabilityofpreventing roughening of its contact surface. [Means for Resolution] To solve the above-described problem, a switchgear of thepresentinventionischaracterizedbyincluding:aplurality of switch units each having a fixed electrode and a movable electrode disposed to be opposed to the fixed electrode, the movable electrode being closed or opened with respect to the fixedelectrode; andoperating means configuredto operate the movable electrode being closed or opened with respect to the fixed electrode of each of the switch units, wherein the operating means is configured of one motive part and two follower parts that intermittently operate with each other, and part of each of the follower parts touches the motive part, thereby in a condition that moving force is not transmitted from the motive part to the follower part, a state of the follower part is fixed, and in a condition that the motive part shifts from an initial position to a final position, a state of one of the follower parts is allowed to transit, and a state of the other of the follower parts is changed with a delay from such state transit, thereby the switchunits are drivenwhile atime delay is produced.
