Abstract

1535319 Indicators for switches LUCAS ELECTRICAL Ltd 26 Feb 1976 [12 March 1975] 10260/75 Heading H1N An electric switch has a position indicator including a light transmissive member 23 which is movable relative to the switch body 11 so as to be withdrawn from an exposed visible position (as shown) when the operating member 12 is depressed. The member 12 carries movable contacts 14 which disengage fixed contacts 15 when the member 12 is depressed, a detent 16 which disengages on further depression of member 12, and a transparent or translucent element 19 which may be provided with a coloured filter. The member 23 may carry a coloured filter which intercepts light from a lamp 18 to a symbol (21, Fig. 3, not shown) on element 19 in the depressed position or in both positions of member 12, or may carry a shutter which partially or fully obscures this light when member 12 is depressed. In an alternative embodiment (not shown) the member 23 is mounted in the housing 11 instead of in the member 12.
