Abstract

335,412. Telefunken Ges. f³r Drahtlose Telegraphie. Oct. 25, 1928, [Convention date]. Plug couplings combined with switches. In a wireless receiver adapted for use as a gramophone by the insertion of the pick-up means are provided to short-circuit the connecting points for the pick-up when the latter is not in use. Fig. 4 shows a plug having an insulating piece i adapted to remove a short circuit by a resilient member c when the terminals a, b are engaged.
