<p>PURPOSE:To reduce the capacity of an electromagnetically operating body by attracting a releasing member against a comparatively weak return spring at the beginning of switch-on to carry a current to the electromagnetically operating body, and making the releasing member abut against an anchoring member, and releasing an anchored state by the rotating action of the anchoring member. CONSTITUTION:When the current is carried to an electromagnet 15 in order to release the anchored state between the anchoring projecting piece 5 of an operating member 1 and the anchoring hole 10 of the anchoring member 6, the free end part 11' of the releasing member 11 is attracted, and the releasing member 11 rotates against the comparatively weak return spring 13, and abuts against the projecting part 8 of the anchoring member 6. In this abutting operation, since the rotation of the releasing member 11 is performed instantaneously by an attracting action, a hammering phenomenon is caused within the range of an interval S, and the anchoring member 6 rotates vigorously by this phenomenon, and engagement between the anchoring hole 10 and the anchoring projecting piece 5 is released in a state that the anchoring member 6 rotates sufficiently together with the releasing member 11, and the operating member 1 is returned automatically by a return spring 4.</p> |
