Abstract

1469235 Indicators for switches LUCAS INDUSTRIES Ltd 31 July 1974 [16 May 1973] 23264/73 Heading H1N A switch in which an actuating element 15 is settable to any one of a plurality of positions corresponding to respective switching states has a plurality of electrically energizable light sources 19 adjacent said element 15 at respective locations corresponding to said positions, and a masking element 22 movable by said element 15 and having a portion which can overlie the light source corresponding to the selected position, for the time being, of said element 15. As shown a rotary switch 12 has a spindle 14 carrying a transparent cup-shaped element 15 which encloses an opaque insulating body 17 having compartments 18 with openings 20 for light from respective lamps 19 therein. A lamp 19 may be energized to indicate a desired switch setting and when the opaque mask 22 obscures the lamp the switch is set as required. The mask 22 may cover the surface 21 of element 15 and have transparent or translucent portions to provide indication of switch setting. Alternatively, or additionally, mask 22 may be selectively coloured.
