US Patent 11955300 Switch

A vacuum circuit breaker serving as a switch includes a pair of electrodes that serve as a stationary electrode and a movable electrode, a handler including a movable shaft and a housing that operate as a first mover in withdrawing the movable electrode from the stationary electrode and closing the movable electrode toward the stationary electrode, a movable shaft that is connected as a second mover to the movable electrode, a coil spring that is connected as an elastic between the first mover and the second mover to press the movable electrode against the stationary electrode, and a shock absorber that attenuates as an attenuator contraction of the elastic when the movable electrode is withdrawn from the stationary electrode.
