Abstract

696,208. Automatic exchange switches. STANDARD TELEPHONES & CABLES, Ltd. July 7, 1950 [July 13, 1949], No. 18501/49. Class 40 (iv). A combined switch multiple and contact bank consists of a strip 33 of insulating material, e.g. resin-impregnated paper, longitudinal multipling tracks 37 deposited in particulate form, e.g. printed, on one side of the strip, transverse groups of tracks 34 similarly printed on the other side of the strip and terminating at an edge to form bank contacts 35 and connections through the strip 33 for connecting the multipling tracks 37 with the appropriate transverse tracks 34. Arcs for switch-wipers may be provided at both longitudinal edges. A group selector bank comprises two strips mounted back-to-back with the multipling tracks staggered, the superposed transverse track laminations constituting the line contacts of each outlet. Specifications 569,388, 646,921, [both in Group II], 696,203 and 696,204 are referred to.
