Claims

[Scope of utility model registration request]

a contact holder that also serves as a yoke; an armature that is rotatably supported by the contact holder and has a facing portion facing the contact holder; and between the contact holder and the armature. an electric circuit section that attracts the armature to the contact holder by passing an abnormal current therethrough; and a movable contact that is supported by the contact holder, is connected to the electric circuit section, and has a movable contact. a fixed contact that is disposed opposite to the movable contact so that the movable contact comes into contact with and separates from the movable contact when the movable contact rotates, and a fixed contact that is suspended between the rotating part of the armature and the movable contact side of the movable contact. and a reversing spring whose reversal dead center is located between a position where the armature is separated from the contact holder and a position where the armature is in contact with the contact holder, and a rotation center position of the movable contact. is provided on the opposite side of the movable contact and protrudes in the opposite direction to the movable contact, and is pressed against the armature when the armature rotates in a direction approaching the contact holder, and is also pressed as the armature rotates. A forced opening device for a circuit or disconnection device, comprising a forced opening part having a shape whose position moves toward the center of rotation.
