Abstract

308,951. Wynne, A. C. Jan. 21, 1928. Divided on 307,584. Plug couplings combined with electric switches. The switch arm d actuated by a cam-plate a with which the operating plug j engages as described in Specification 13455/12, is positively moved durina withdrawal of the Plug to the final " break " position, irrespective of the operation of the snap-action spring h and roller g or of the subsidiary spring m connecting the arm d with the plate a. When the roller g has passed the cam b on withdrawal of the plug j, it contacts with a circular surface e that allows the plate a to turn further so that the shoulder c<2> again engages the tongue d<1> and positively moves the arm d. The claw i is so shaped that this further movement is positively effected when the plug j is completely withdrawn.
