Abstract

1,143,805. Vacuum switches; actuation of switches. ENGLISH ELECTRIC CO. Ltd. 1 Aug., 1967 [4 Aug., 1966], No. 34928/66. Heading H1N. Actuating mechanism for a vacuum switch or other device includes a magnetic coupling comprising an actuator rod 15 having an armature 14 whose face 14A is engaged by a linearly movable cam driven magnetic core element 11 and held in engagement therewith by energized coil 12. In operation a motor 23 rotates a cam 22 to allow the element 11 to move initially downward under the bias of gravity and/or springs 24. If the coil 12 is energized when faces 11B and 14A come into engagement, the actuator rod 15 moves with the element 11 as the revolution of the cam 22 is completed, so that contacts 8, 9 of a vacuum switch 10 are closed. The contact 9 and actuator rod 15 are biased by springs 26 acting on a cross-bar 25 on the rod 15 and release is effected by deenergization of the coil 12 or by energization of an opposing release coil 13. The vacuum switch may have resilient contacts with or without the biasing springs 26.
