ABSTRACT:
An arrangement for controlling the activation of an electrical appliance. The arrangement utilizes a capacitive sensor to recognize the physical proximity of a user (e.g., a hand) to an internal capacitive sensing means. The capacitive change is applied as an input to an electrical control circuit so as to ultimately provide an electrical control signal to an associated electrical appliance. The arrangement does not require direct physical contact to activate any appliance, and may be used to control various power levels associated with a particular electrical appliance (e.g., light intensity for a "dimmer" switch, sound volume for an audio system, activation and trigger signals to an alarm system). The arrangement may be embedded within the wall of a structure (i.e., not visible) and still provide the capacitively-activated control function.
