Abstract

518,764. Two-part couplings combined with switches. CRABTREE & CO., Ltd., J. A., McLOUGHLIN, H. F., and HARRISON, B. G. Aug. 23, 1938, No. 24738. [Class 38 (i)] The switching action of a combined socket and switch is performed solely by pressure applied to the inserted plug member. The socket contacts e, g are mounted on a movable block a carrying contacts e<1> that co-operate with fixed contacts f. The block a may be mounted to rock on a pivot b at the centre or towards the top or bottom ends of the fitting. Alternatively the block may slide on the base. Devices for locking the switch in the open position when the plug member is disengaged and for fastening the plug member in the socket when the switch is closed, such as described in Specification 518,765, may be provided and a snap action switch mechanism, such as described in Specification 518,519, [Group XXXVII], may be incorporated.
