a movable arc contact that has a hollow part for blowing out arc-extinguishing fluid therein and opens and closes with respect to the current-carrying contact; and a movable arc-contact that follows the movement of the movable arc contact and precedes the current-carrying contact during the closing operation. In a switchgear equipped with an arc contact that is in contact with the current-carrying contact and later opened from the movable arc contact during an opening operation, a recess is entirely formed in one of the contact portions of the movable arc contact point and the arc contact point, The switching device is configured to connect the movable arc contact and the arc contact in the recess. .
