を特徴とした電磁接触器。A fixed iron core and a coil with a closing winding and a holding winding are provided on the substrate base, and a fixed contact stand with a fixed contact attached is placed on top of this coil, and this is supported by a return spring as a guide. a movable contact stand provided with a movable iron core facing the fixed iron core and a movable contact facing the fixed contact;
A cover that covers this and a plurality of grooves and notches are provided on the outer surface of the fixed contact base, and a protrusion provided around the movable contact base is loosely fitted into the notch and protrudes and slides into the groove. In a DC-operated electromagnetic contactor that can be equipped with one or more auxiliary contact units each having a fitting protrusion and an operating rod in contact with the protrusion, the operating rod of the auxiliary contact unit is pressed against the movable contact base. An auxiliary contact unit is provided so that the operating rod and the push part come into contact with each other due to the suction operation of the movable contact base, and the contact is connected in series to the closing winding through the contact that opens with the suction operation of the unit. An electromagnetic contactor characterized by connecting a holding winding.
