Abstract

1384412 Indicators for switches LICENTIA PATENT-VERWALTUNGS-GmbH 4 Aug 1972 [4 Aug 1971] 36582/72 Heading H1N A push-button switch comprises a housing 10 containing a switch unit 13 and a lamp, the lamp and one or more additional components being accommodated in a closed component 17 which has a lamp window and is arranged between the housing cover 11 and the switch unit 13. The closed component 17 contains a lamp (21, Figs. 4, 5, 6, not shown) with series resistor (22) held in position by a snap cover (19) having a window (20) which aligns with window 12 in cover 11. Terminals (24) allow connection of component 17 to switch unit 13 or to an external circuit. If lamp 21 is a glow discharge type a parallel resistor (23) may also be provided to reduce interference and to prevent the lamp lighting due to stray capacitance (30, Fig. 7, not shown) of lines when its circuit has not been closed.
