Claims (1)

[Scope of claims for utility model registration] (1) Contact opening/closing device for load circuit control, and
This contact opening/closing device is used in a remote control relay equipped with an electromagnetic device as a driving means for opening and closing, and is fixed to a shaft so that it can swing forward and backward, and has supporting parts on both sides of the shaft and a protrusion on one side. A movable body, which is pivoted on the side of the protrusion of the oscillating body and is driven in forward and reverse directions by the action of an electromagnetic device, has a movable contact at the tip and a hole in the center, and has a hole in the center. A movable contact in which the protrusion of the rocking body is inserted and the center part is removably supported on the movable body pivoting side of the rocking body so that the center part and the base face both supporting parts of the rocking body. A fixed contact facing the movable contact, a contact pressure spring placed on the oscillating body to urge the base side of the movable contact toward the oscillating body, and a stopper provided on the back side of the movable contact are respectively provided, and the movable body moves forward. When the movable contact of the contact comes into contact with the fixed contact, the contact pressure spring pushes the pivot side support part of the oscillating body and urges the movable body to move backward, and when the movable body moves back, the tip of the movable contact stops. It is a contact opening/closing device in which the base touches a supporting part on the opposite side to the pivot side, and a contact pressure spring pushes this supporting part to urge the movable body to move forward. A notch is provided in the base, and a protrusion is also provided on the side opposite to the pivoting side of the oscillating body, and this protrusion is inserted into the notch to prevent displacement of the movable contact with respect to the oscillating body. A contact opening/closing device characterized in that: (2) The contact opening/closing device according to claim 1, wherein the notch is cut out in a U-shape from the base end of the movable contact toward the distal end.
