ABSTRACT:
A small electronic module to regulate the power delivered to a lamp or similar appliance is plugged into the household electrical outlet and the lamp to be controlled is, in turn, plugged into the module. Each time the lamp is touched the power to the bulb increases by one step, typically in the sequence OFF, DIM, INTERMEDIATE, FULL, OFF. The module device operates by sensing the capacitance change when the lamp is touched and communication between the lamp and the device occurs through the lamp cord.
