Abstract

1429680 Mechanical switches; indicators for switches D A MACDONALD 3 April 1973 [3 April 1972] 15929/73 Heading H1N An electric switch assembly comprises a shaft 52 driving (through gears 58, 60) a shaft 62 at a greater rate of rotation, shaft 62 actuating a first switch element 92; 98, 102, and a second switch element 46 removably mounted at, the rear of housing 44 with a shaft 118 capableof being coupled to shaft 62. Knob 38 drives gear 58 which drives gear 60 which rotatesshaft 62 which drives cylinder 92 which rotates movable contact 98 having fingers 100 which connect printed circuit conductors on plate 102. Detent springs 84, 86 and balls 88, 90 mounted in slots 80, 82, Fig. 6 (not shown), on the back of plate 57 engage detent grooves 96 in cylinder 92. Lamp 70 in plate 57 shines through a hole 72 and through transparent discs 74, 68 to show numbers 78 through aperture 24 in plate 18. A key 136 on shaft 118 slots into slot 138 on the end of shaft 62 to couple them together. A plurality of switch elements 46 may be mounted in line. A number of switch assemblies may be mounted side-by-side, Figs. 1, 2 (not shown), joined by bolt 16 between end brackets 28, 30.
