ABSTRACT:
A motion-activated electrical switch has a pair of spaced electrical circuits, each disposed on a support, and an electrical conductor interposed between spaced from and electrically insulated from the electrical circuits. An electrically conductive movable element is structured to assume a first position in contact with the electrical conductor and one of the electrical circuits and a second position out of contact with the electrical circuit is provided along with a power supply for energizing the switch. In one embodiment, the electrical conductor is a closed shape having an opening defined therethrough. A pair of conductive strips may be connected to the electrical conductor and to one of the electrical circuits such that movement of the electrically conducted movable element may serve to complete the circuit or to break the circuit.
