Abstract

794,525. Contact members for switches. TELEPHONE MANUFACTURING CO., Ltd. Aug. 28, 1956 [Sept. 1, 1955], No. 25132/55. Class 38 (5). A contact spring stack comprises an insulating moulding 60 having a fixed contact blade 35 clamped between it and an insulating plate 61, the moving blade 70 being subsequently inserted in a recess 63 formed between the plane upper surface of an insulating plate 62 and the recessed lower surface of the moulding 60. The recess 63 is of U-shaped cross-section due to longitudinal ridges 64, 65 separated by a notch 66, and is widened at its entry end by shallow parts 67. The blade 70 is inserted by placing its U-shaped section fixed end 75 at the entry of the recess and moving it therealong until an enlarged part 74 abuts the ends of the parts 67, a tongue 77 bent out of the plane of the blade springing into the notch 66 to prevent its withdrawal. The stack is formed by similarly mounting further blades 35, 70 one above the other in alternate fashion, and a number of such stacks may be mounted side by side for use in the selector switches disclosed in Specification 728,891, 781,851, 781,852 [both in Group XXXIX], in which instance the mouldings 60 have a corresponding number of recesses 63 (Figs. 9, 10, not shown). The free end 72 of the blade 70 may be circular as disclosed in Specification 787,996.
