Abstract

PURPOSE:To improve sensitivity and enable low consumption power with increasing suction force of an armature by providing a second yoke having a second magnetic connecting part magnetically connected to a first yoke and a return spring for energizing an armature to a magnetic pole of a permanent magnet. CONSTITUTION:A closed magnetic circuit is formed by a first yoke 3 and an armature 2 without containing a permanent magnet 5 in the time of excitation of a coil 1. In the time of starting of the armature 2 the generating magnetic flux of the coil 1 and the permanent magnet 5 is negated in the case of each one side gap G3 and overlapped in the case of the other side gap G1 and so it is approached to a closed loop in which the generating magnetic flux of the coil 1 does not include the permanent magnet 5 in a magnetic path with highly sensitively starting operation as the armature 2 is operated, so that, for instance, varying width of magnetic suction force of the part in which the specified spring load of an electromagnetic contactor is increased can be enlarged and so high sensitivity can be made even if the one-sided spring load such as the electromagnetic contactor is adjusted. Therefore, low consumption power can be enabled.
