ABSTRACT:
There is disclosed a rotary switch assembly comprising a lamp plate adapted to accommodate a plurality of switchable lamps. A power contact plate is positioned above said lamp plate and contains spring loaded contacts which coact with terminals associated with said lamp plate to enable energization of any selected one of said plurality of lamps.
The two plates are positioned and held in alignment by means of a clamping ring into which both plates are located. The clamping ring assures proper detenting of the rotatable lamp accommodating plate to ascertain reliable switching and further assure that any bulb selected will have its optical axis properly aligned.
