To provide a switchgear which damps the shock attendant on switching operation, has reliability on the switching operation with little part damage.
The switchgear comprises a switch part 3 composed of a stationary electrode 1 and a movable electrode 2, a movable shaft 5 extending from the movable electrode 2 and an operating mechanism 9 for opening and closing the switch part 3. The operating mechanism 9 is equipped with a driving mechanism 21 for driving the movable shaft 5, a holding mechanism 22 for holding an opened or closed state and a reducing means 23 for damping the shock attendant on a switching operation. A contact plate 25 fixed to the movable shaft 5 between a closing reduction damper 24a and an opening reduction damper 24b is moved upon closing and opening to contact with the respective reduction dampers 24a and 24b, whereby the shock attendant on the switching operation can be damped to prevent part damage and switching operation failure.
