ABSTRACT:
A system to control power from a source to a load consists of a cover plate, a touch-operable device that is mounted behind a flexible area on the cover plate, and a power control circuit that responds in accordance with a signal generated by the touch-operable device. The system is operated by touching a point within the flexible area of the cover plate to activate the device. In a preferred embodiment, the system provides power over a continuous range of values, depending on the particular point at which the device is activated. Alternatively, the system operates as a switch, alternately turning power on or off when any point on the flexible area is touched. The control circuit preferably includes an electronically adjustable voltage divider. The system is well-adapted to permit control of power to a load from multiple locations. The appearance of the front surface of the cover plate can be dictated entirely by aesthetic considerations and can, if desired, be entirely featureless.
