Claims

[Claims for Utility Model Registration] A fixed contact provided on a fixed electrode and a movable contact provided on a movable electrode are housed together with gas in a sealed container using a bellows, and a fixed contact provided on a fixed electrode and a movable contact provided on a movable electrode are housed together with a gas. The movable electrode is exposed outside the sealed container, and the fixed contact and the movable contact press or press the movable electrode in response to their own suction or release action, and the sealed contact portion is always in a contact open state. The armature includes an electromagnetic part having an armature to be released, and a rigid driving member whose base end abuts against the base end of the armature and is supported so as to be angularly displaceable, and whose tip can press the movable electrode. A spring member is provided between the armature and the driving member, and when the armature is in the suction position, the armature and the driving member are linked only through the spring member, and the spring force of the spring member increases, so that the armature is at least in the release position. In some cases, in a sealed contact device in which the armature and the drive member operate in direct cooperation to reduce the spring force of the spring member, a fulcrum is formed at the proximal end of the drive member, and the drive member A sealed contact device characterized in that the fulcrum portion thereof is supported by abutting on a contact portion provided at the base end of the armature.
