Abstract
An electromagnetic contactor having an electromagnet consisting of a fixed core and an operating coil mounted on the fixed core, a plurality of fixed contacts, a crossbar disposed above the fixed core, a plurality of contact bars associated with the crossbar and each provided with a pair of movable contacts located opposite the corresponding fixed contacts, respectively, a movable core joined to the lower portion of the crossbar opposite to the fixed core, and a rigid frame consisting of two parallel polygonal bars and two parallel connecting bars interconnecting the respective opposite ends of the polygonal bars. The crossbar and the movable core are supported pivotally on the rigid frame. One of the polygonal bars is supported rotatably at the opposite ends thereof in bearings provided on a stand, while the other polygonal bar is urged upward by springs so that the rigid frame will swing to bring the movable contacts into contact with the fixed contacts, respectively, when the operating coil is energized to attract the movable core to the fixed core.
