Abstract
A flap-armature electromagnet comprises a U-shaped yoke, a pole core, a coil, a flap-armature, a compression spring and a coil spring. The flap-armature is rockingly supported on the yoke by means of projections formed at the upper rear end of the yoke and notches formed at both sides of the flap-armature. Each end of the coil spring is connected to each of the projections for pressing the flap-armature on a rocking axis of the flap-armature.
