Claims

[Claims for Utility Model Registration] (1) An arc contact with a high melting point is provided on one side in the operating direction, and a conductive contact with low resistance is provided on the other side, and a return spring biases the arc contact in the direction in which it faces. a supported first contact; a second contact having a high melting point arc contact opposite the arc contact; and a low resistance conductive contact opposite the conductive contact; and an arc of the second contact. driving means for bringing the conductive contact of the first contact into contact with the conductive contact of the second contact against the return spring by pressing the contact against the arc contact of the first contact; A contact opening/closing device in which the arc contacts are brought into contact with each other before the conductive contacts when the contacts are turned on, and the arc contacts are opened after the conductive contacts when the contacts are turned off. (2) The first contact is formed of a plate spring and also serves as the return spring, and the second contact is formed of a plate spring and connects the arc contact and the conductive contact of the first contact. The tip of the leaf spring is curved so as to surround the arc contact and the conductive contact of the second contact are provided inside the leaf spring, and the second
A contact opening/closing device according to claim (1) of the registered utility model, wherein a stopper for preventing movement of the conductive contact is provided on the opposite side of the conductive contact of the contactor.
