Abstract

1,081,616. Cam-operated switches. PLESSEYU.K. Ltd. May 14, 1964 [May 31, 1963], No. 21805/63. Heading H2B. A switching device comprising a plurality of switch units includes a shaft 14, manually rotatable to select a switch unit by engaging the corresponding clutch unit 11 on a second shaft 9, which is then manually rotatable to operate the selected switch unit. Each switch unit comprises a drum (2) (Fig. 2, not shown), carrying several cam rings (18), each with a cam riser (19) for moving its associated contact spring (20) into engagement with a common contact (21), a ring gear (7) meshing with a gear 8 loose on shaft 9, and an indicator ring 4 integral with the drum sleeve (3) which is rotatably journalled on a fixed shaft 1. Spring- pressed balls (6), in a bore of the shaft 1, engage recesses (5) in each drum sleeve (3) to index the sleeve, and thus ring 4, relative to the shaft 1. Shaft 14 carries clutch operating discs 15, each having a detent 16 engaging a bracket 13 to push it, against a load spring 17, sufficiently to engage the dogs 10, 12 of the corresponding clutch 11. The indicator rings 4 are seen through windows (24) and illuminated by a lamp (25). Driving dogs 12 are rotatable with but axially slidable on shaft 9, while driven dogs 10 are fast with gears 8 which idle on shaft 9.
