Electromagnet and switch operating mechanism

摘要

An electromagnet according to the present invention comprises a fixed core 1 formed by side legs 2b provided on both sides of a central leg 2a produced by laminating a plurality of steel plates, and a yoke 2c for connection between the central leg and the side legs, the central leg, the side legs, and the yoke being integral with each other; an exciting coil 4 wound around the central leg 2a; and a moving core 3X opposed to the central leg and the exciting coil which is moved along the side legs; wherein length of the side legs 2b is longer than that of the central leg; and the moving core 3X opposed to the central leg 2a has a projection 3a extending to the central leg side. Therefore, occurrence of eddy current is reduced and attractive force is increased. <IMAGE>
