Abstract

634,265. Two-part couplings combined with switches. CRABTREE & CO., Ltd., J. A., and MORGAN, R. W. Nov. 28, 1947, No. 31503. [Class 38 (i)] [Also in Group XXXVII] A wall socket for a three-pin plug has a double-pole, push-bar switch (see Group XXXVII) arranged so that there is no frontal projection of a switch-actuating member, the push bar a, a<1>, a<2> being housed in recesses in the rear of the cover-plate c and the other switch parts in recesses in the socket base f. Each of the two switch units forming the double-pole switch has one of its fixed contacts k extended from a bifurcated socket contact m and the other of its fixed contacts k<1> has a downwardly-bent arm k<2> which engages in the slots n<1> of a terminal n. The contact-members k, k<1>, m are retained in grooves and recesses formed in the base f.
