Abstract

205,209. Wood, A. F., Stott, W., and Telephone Manufacturing Co., Ltd. July 14, 1922. Selectors for automatic exchanges have their terminals formed by bring- ing a portion Y of an insulated wire X from the back to the front of a panel through two holes and removing the insulation from that portion. The left-hand terminals are for speech, the others for testing, so that any two speech wires are separated during conversation by a dead wire. This is stated to prevent inductive troubles. Specification 21347/94 is referred to.
