Abstract
There is disclosed a rotary switch assembly which comprises a lamp support plate adapted to accommodate a plurality of switchable lamps. A power contact and a detent plate is positioned above the lamp plate and contains spring loaded power contacts which coact with terminals associated with the lamp support plate to enable energization of any selected one of said plurality of lamps. The power contact and detent plate further includes spring loaded detents which cooperate with detent recesses on the lamp support plate to assure optical alignment. These spring loaded detents are positioned approximately opposite to the power contacts and exert counter balancing forces to assure low shaft friction as the lamp support plate is rotated during lamp selection.
