In a second embodiment of the invention, light can shine onto the rear of the knob to be reflected back to the face plate to form a halo. The neon bulb light source is positioned to shine through the conventional central opening of the switch plate and illuminate the rear surface of the translucent knob. The knob is at least in part translucent for dispersing illumination impinging upon the knob and for appearing luminescent. The light source is positioned adjacent to the potentiometer operating shaft and an opening in the forward surface of the dimmer switch housing. A combined on-off switch and potentiometer operating shaft extends through a central opening through the switch plate for access by an operator a manually graspable, rotatable knob is positioned on the shaft and is spaced away from the switch plate. In a decorative dimmer switch apparatus a housing for the dimmer switch apparatus for an incandescent light an on-off switch within the housing, a variable potentiometer spaced adjacent the front surface of the housing, and a neon bulb light source, connected in parallel with the dimmer switch control mechanism, and positioned at least in front of the potentiometer and a switch plate over the housing.
