Abstract

1,065,902. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. July 30, 1965 [July 31, 1964], No. 32746/65. Heading H4K. A cross-bar switch comprises three sections CO, CA, CE having common horizontal operating bars for the purpose of connecting incoming and outgoing lines to link circuits AL and of connecting link circuits to registers EN. The horizontal bars are operable to either of two positions and in each section the contacts are multipled horizontally. To connect the lines to a link circuit appropriate horizontal bars are operated together with bar BR14. The links AL may be connected to the contact levels controlled by bars BR1 ... BR10 and the registers EN to the levels controlled by bars BR11 ... BR14, so that one bar in each set requires to be operated.
