Switch

A switch comprising:

• a plurality of electrode portions each including a fixed electrode and a movable electrode, the movable electrode being capable of moving with respect to the fixed electrode;
• an operating device including a first movable portion for collectively performing tripping operation for the plurality of electrode portions, a plurality of the movable electrodes being collectively separated from a plurality of the fixed electrodes in the tripping operation;
• a second movable portion integrated with the plurality of the movable electrodes of the plurality of electrode portions;
• a first elastic part to apply pressure for bringing the plurality of the movable electrodes into contact with the plurality of the fixed electrodes, the first elastic part being disposed between the first movable portion and the second movable portion;
• and
• a damping mechanism disposed between the first movable portion and the second movable portion and disposed parallel to the first elastic part to damp contraction of the first elastic part during the tripping operation.
