装置。 A fixed contact plate in which the fixed contacts constituting the contacts together with the movable contacts are provided on one side and both edges are formed in a straight line, and the fixed contacts are arranged on both sides of the fixed contact plate and one end is continuous with one end of the fixed contact plate. At the same time, a pair of drive coils, the other end of which is located at the other end of the fixed contact plate and is curved in such a way as to protrude toward one side of the fixed contact plate on which the fixed contact is provided, are disposed at the other end of the fixed contact plate through a gap. A terminal plate that is installed and continuous to the other end of the drive coil is integrally formed by bending a conductive sheet metal punched into a predetermined shape, and is connected to the fixed contact plate on one side of the fixed contact plate where the fixed contacts are provided. An arc extinguishing grid device is provided to extinguish the introduced arc by straddling the terminal plate. The fixed contact is arranged between both ends of the drive coil, and the fixed contact plate and the end surface of the fixed contact are set substantially flush between the fixed contact and the arc extinguishing grid device, and the terminal of the fixed contact plate An arc extinguishing device in which a tongue piece is formed by bending the end of the plate so that the distance from the arc extinguishing grid device is greater than that of the terminal plate.
