Abstract

762,999. Contact members for switches. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. March 31, 1955 [April 5, 1954], No. 9957/54. Class 38(5) A switch contact comprises a flexible insulating strip 1 having a conducting line 2 printed on one surface and a contact stud 4 fixed to the strip in contact with the line. Fig. 3 shows a pair of superposed strips 1, the lower one being operable by a cam 9 to control the contacts 4. Each strip 1 may have a plurality of lines 2, Fig. 5, the free end of the strip being slit at 9 to counteract the effect of any tranverse warping. Figs. 6, 7 (not shown) show three superposed strips 1 functioning as a changeover contact arrangement.
