ABSTRACT:
A three-position toggle switch having a transparent toggle lever (28) illuminated in its natural color in the center position and illuminated in second and third colors in its respective left and right positions. Molded color filters (32, 34) are structurally attached to the interior end of the lever by dovetail slots (28k, 28m) and dovetail ribs (32b, 34b) and are retained thereon by confinement within the interior switch cavity (2a). The filters (32, 34) have offset legs (32a, 32b) depending toward a lamp (8) in the switch base (2) to reflect or redirect light rays from the lamp (8) to enhance color separation while permitting an inexpensive, unfocused lamp to be utilized.
