Abstract

763,092. Mechanical switches without quick action. PLESSEY CO., Ltd. Feb. 11, 1955 [Jan. 29, 1954], No. 2727/54. Class 38(5) A rotary wafer switch has a rotor comprising two insulating discs 8 carrying contact strips 11. The latter are attached by lugs 12 passing through aligned apertures in recessed portions 15 in the surfaces of the discs, which are located by flanges 8a engaging the stator 1. The discs may be moulded from polystyrene.
