Abstract

328,228. Automatic Telephone Manufacturing Co., Ltd., and Smith, S. R. Jan. 21, 1929. Automatic exchange selectors.-The wipers 3 of a Strowger selector make contact between individual contacts and contact bars common to a plurality of positions. The wipers are fitted with projections engaging, when the wipers are off normal, with conductors 15 mounted by springs 13 on the selector framework. Wiring to the conductors is facilitated by tags 18. In the home position the conductors 15 coincide with the grooves 16 and the springs 13 are supported by members 14 thus providing no additional frictional resistance to the vertical movement of the shaft.
