ABSTRACT:
A composite, push-pull headlight and rotary switch (1) having a front bracket area (4) and a panel light dimming rheostat (62/91) for use in a vehicle with, for example, a dome light switch and a supplemental fluorescent panel light system switch, utilizing two, parallel, spaced panels (6 & 7) having three, laterally extended, operative planar surfaces, all located in the front bracket area. The front panel (6) has on its back side a rheostat planar surface including a series of circularly disposed, peripherally spaced, resistive layers (62), which, in conjunction with a rotatable, sweeping, rheostat contactor arm (91), serve the rheostat dimming function for the panel lights. The rear panel (7) has on its front side (71) a detent planar surface having three protrusions (72A-72C), which serve as detent positions in cooperation with a flexible, rotatable detent arm (92) sweeping across it, as the control knob shaft (8) is rotated, along with an axially extended and movable, protruding plunger (73), which also extends to the other side ( 74) of the panel to coact with switch contactors (75A & 75B) for the "dome" light bypass circuit, and a switch circuit planar surface on the opposite, back side having spaced conductive surface contacts (76& 77) which control the main "dome" light circuit and the fluorescent panel light circuit. A common hub (90) carries the rheostat contactor arm and the detent and plunger actuator arm, while on the other side of the second panel there is included a conjunctively rotatable dome & fluorescent contactor structure (93) scrubbing against the switch circuit planar surface.
