Abstract

PURPOSE:To decrease the number of parts and to simplify the assemblage by integrating a side wall and an end plate on the one side of a bobbin and accommodating a permanent magnet in a space provided thereby. CONSTITUTION:With a field coil 2 excited, a movable core 7 is moved and forced to be drawn toward a fixed core 4. In this state, a magnetic circuit 100p (i.e., N-pole of a permanent magnet 5 fixed core 4 movable core 7 yoke 6 S-pole of a permanent magnet 5) is formed so that this operating state is self-hold even if the field coil 2 is deenergized. Afterward, with the field coil 2 energized in the reverse direction, the movable core 7, drawn to the fixed core 4 by a force of the permanent magnet 5, is released from the latter and returns to its original position by the force of a spring 8.
