Abstract

572,686. Electromagnetic relays. TELEPHONE MANUFACTURING CO., Ltd., TERRY, R. S. G., and HOLT, J. W. Nov. 3, 1943, No. 18239. [Class 38 (v)] A relay designed to resist shock has its armature 8 pivoted at its centre of gravity 7 and acting on members of a contact system arranged at opposite sides of its pivot. In the form shown, the armature is attracted by the poles 5 of an electromagnet arranged behind the base 1 and is returned to the position shown by spring contact wires 9 which engage forks 14 on arms 13 fixed to the armature. The two contact wires 9 are arranged between two pairs of fixed contact pins 11 and engage the outer pins or the inner pins according to whether the magnet is de-energized or energized. In a modification the relay is polarized, and the armature rocks one way or the other according to the direction of the current.
