Abstract
An illuminated controller having a membrane potentiometer for use as a light dimmer or other voltage controlling device. The controller has a backplate that acts as a sturdy base, and a cover, having sidewalls and a top wall with a central opening. The cover is mounted on the backplate and a layered structure is interposed between the cover and backplate. The layered structure includes a membrane potentiometer for varying voltage, and an electroluminescent panel, for generating light to illuminate the controller.
