ABSTRACT:
A dimmer device is provided with an improved illumination of its control knob. The light is transmitted to the knob from a light source such as a glow lamp positioned close to the shaft of the control knob. An opening is provided in the dimmer housing at this point so that light can pass from the dimmer to and through the conventional opening of a conventional switch plate. A plastic lens is mounted in the opening in the housing to close it against entry of dust or articles which might damage the glow lamp or the internal controls of the dimmer. The lamp is held in place at the opening in part by a portion of the internal structure of the dimmer and in part by cooperation between the lamp power supply and the lamp protecting lens.
