Claims

[Claim for Utility Model Registration] A sealed contact device in which a movable contact whose one end is led out to the outside and which is fixed to the other end of a movable electrode and a fixed contact that makes contact with and separates from it are hermetically sealed using a bellows, and an armature made of iron. An electromagnet that is attracted and released by the core, a rigid arm whose base end is rotatably supported by an armature, and a rigid arm whose base end is fixed to the armature and whose tip is engaged with the engaging part of the arm to form the armature. and a spring biased to press the arm, and when the armature is attracted and held by the iron core, the arm resists the biasing force of the spring and has a small gap between it and the armature. In an electromagnetic relay whose tip presses and drives a movable electrode to bring the movable contact into contact with a fixed contact, a second movable contact is provided at the tip of the spring, so that when the armature is released from the iron core, it contacts the fixed contact. An electromagnetic relay with a second fixed contact attached to the contact position.
