Abstract

1351693 Electromagnetic selector switches GENERAL ELECTRIC CO Ltd 4 Sept 1972 [8 Sept 1971] 41917/71 Headings H1L and H1N A cross-bar switch of the type described in Specifications 1,306,072 to 1,306,076, 1,327,932 and 1,327,933 has an interposer arm 101 and a co-operating interposer member 102 for operation of each crosspoint set of contacts and the interposer arms 101 are provided with resilient support means 191 which allow for lost-motion between a row co-ordinate member 181 and the associated interposer member 102. Operation of a crosspoint occurs when the member 181 is moved to pivot the arm 101 about its end 193 to move the interposer member 102 in the slot 97 of the column actuator 198 so that when the actuator is rotated about pivot axis 81 the interposer member 102 lifts the contact comb 32. If the member 102 is in a position which does not allow movement to the right when the row member 181 moves the arm 101 will rock about its end 104 against the bias of the spring 191 and its end 193 will move away from its bearing member 86.
