Claims

[Scope of Claim for Utility Model Registration] A sealed container in which an electrically insulating gas is filled to form an airtight space, a fixed electrode with a fixed contact at its tip, and a sealed container that is driven in the axial direction. A movable electrode having a movable contact at one end that contacts and separates from the fixed contact in the axial direction, a cylindrical portion through which the movable electrode is inserted, and a bellows having one end fixed to the movable electrode and the other end fixed to the cylindrical portion. In the sealed contact device, the movable contact is provided with a second fixed contact that comes into contact with the movable electrode on a side surface substantially parallel to the axis of the movable electrode before the fixed contact and opens later. A sealed contact device characterized by:
