Abstract
644,068. Indicators for switches; switch handles; mechanical switches. BRUCKER, J. Sept. 17, 1947, No. 25417. Convention date, Sept. 6, 1946. [Class 38(v)] An indicating lamp is fitted in the handle 'or knob of a rotary switch to indicate its switching position, the lamp connections being arranged to that the knob may be fitted to an existing switch. In Fig. 1, the insulating knob 4 has a metal bush 3 and is fixed on the spindle 2 of a switch 1. A bayonet cap filament or glow lamp 6 is fitted in a bore 5 in the knob 4 and is covered by a glass 8 which is retained by a threaded ring 7. One contact 9 of the lamp is earthed through the bush 3 and. spindle 2, whilst the other, 10, is connected to a source of supply through a spring arm 11, studs 12 and terminals 14. A stud 12 is provided for each switch position, but that at the off position is not connected to the supply so that the lamp is not lit in this position. The member 13 carrying the studs 12 is shaped so that it may be placed or fixed on the switch casing and a cap 15 covers the terminals 14. In a modification, Figs. 2, 3 (not shown) the knob has an extension in the shape of an arrow which houses a small tubular lamp, and in other modifications a slip ring may be used instead of the studs 12 and the knob may be made of transparent material.
