Claims

[Claims for Utility Model Registration] (1) A movable iron core and a movable contact support driven by the movable iron core are coupled to each other through a pin, and both a main contact and an auxiliary contact are connected to the movable contact support. In an electromagnetic contactor that supports a movable contact and is housed in a case so that the main contact and the auxiliary contact open and close at the same time; a main movable contact support that has recesses in the insertion openings on both sides and supports the main movable contact; has a first connection hole corresponding to the recess and supports the auxiliary movable contact; and an auxiliary movable contact support; one end of both contact support supports fits into the recess and the other end fits into the first connection hole, and the electromagnetic contactor is attached to the end surface of the other end. coupled by a connector having a second connecting hole into which a movable contact support of a separately formed auxiliary contact unit is fitted; and the case is provided with a window in the side wall of the case to which the connector corresponds; An electromagnetic contactor characterized in that the auxiliary contactor unit can be connected to the auxiliary movable contactor through the window. -(2) Utility model registration In the item described in claim 1; the auxiliary movable contact support and the connector are molded from thermoplastic synthetic resin material, and the auxiliary movable contact support is perpendicular to the first connection hole of the auxiliary movable contact support. A round hole is provided in the direction; a projection is provided in the other end of the connector that fits into the first connecting hole in a direction perpendicular to the connector; and a slit is provided in the end surface in a direction perpendicular to the projection; An electromagnetic contactor characterized by fitting into a round hole. (3) In the utility model registration claim 1 or 2, the fitting portion of the connector is rectangular, and the connector has a recess into which the connector fits, a first connecting hole, and a second connecting hole. An electromagnetic contactor characterized in that each of the connecting holes is rectangular, and the upper and lower walls of the first connecting hole are medium and high.
