Abstract

679,998. Contact members for switches. IGRANIC ELECTRIC CO., Ltd. Aug. 14, 1950. [Aug. 17, 1949] No. 20126/50. 'Class 38 (v). The moving contact assembly of a switch comprises a rectilinearly-movable contact carrier or slide-bar 2 with one or more moving contact-members 4. Each contact-member 4 is supported in a transverse slot 10 in the bar 2, the slot being provided with oppositely-disposed aligned projections 12, 13 for the mounting and locating of a helical spring 11 and the contact-member 4. The latter is a metal stamping with contact tips 19 and an enlarged centre portion 17 which fits between the side walls of the slot 10 and has an opening 18 for receiving the projection 13. For easy assembly, the bar 2 is provided with openings or recesses 15 adjacent the projection 13 so that one end of the contact-member 4 may be used to lift the spring 11 off the projection 13 as indicated in Figs. 7, 8. The contact-member 4 may now be slid into the position of Fig. 5 and then lowered onto the projection 13. The contactmember 4 may be removed merely by raising it and sliding it laterally out of the slot as indicated by the arrow in Fig. 5, the spring 11 being retained in the slot, as in Fig. 7, by the projections 12, 13.
