Wireless light switch system and method, load controller device, and remote switch device
A wireless load control system is provided including one or more wireless switch components and one or more load controller components optionally in one-to-one, many-to-many, many-to-one, and one-to-many wireless communication with each other. A wirelessly-controlled load controller assembly includes an enclosure adapted to fit within a junction box, the enclosure comprising a projecting fitting adapted to fit through an aperture of the junction box to maintain the enclosure in fixed relation to the junction box. A control circuit in the enclosure is provided with an antenna that extends through an antenna port that is disposed within the fitting so that when the load controller is mounted in a junction box, the antenna extends through the aperture of the junction box.
1. A wirelessly-controlled load controller assembly for use with a wireless switch, the load controller assembly comprising a load controller, the load controller comprising:
an enclosure adapted to fit within a junction box, the enclosure comprising at least one port permitting passage of electrical wires from an interior of the enclosure to an exterior of the enclosure, and a projecting fitting adapted to fit through an aperture of the junction box to maintain the enclosure in fixed relation to the junction box, the enclosure comprising an antenna port disposed within the fitting and permitting passage of an antenna therethrough from the interior of the enclosure to the exterior of the enclosure; and
a control circuit comprised in the enclosure, the control circuit being configured to control mains current delivered to a load, the control circuit including a microprocessor in communication with a wireless transceiver and the antenna;
such that when the enclosure is mounted in the junction box such that the fitting extends through the aperture of the junction box to project to an exterior of the junction box, the antenna thus extends to an exterior of the junction box through the aperture.
2. The assembly of claim 1 , wherein the antenna comprises a whip antenna.
3. The assembly of claim 1 , wherein the antenna comprises a wire antenna.
4. The assembly of claim 1 , wherein the microprocessor is configured to control the mains current delivered to the load in response to commands received by the wireless transceiver.
5. The assembly of claim 1 , wherein the enclosure comprises a base and a cooperating lid, the projecting fitting being provided on an exterior surface of a wall of the base.
6. The assembly of claim 5 , wherein the antenna port comprises an aperture through the wall of the base.
7. The assembly of claim 5 , wherein the projecting fitting comprises a threaded nipple.
8. The assembly of claim 1 , further comprising the junction box.
9. The assembly of claim 8 , wherein the junction box comprises a metal junction box.
10. The assembly of claim 8 , further comprising the load, the load comprising a light fixture.
11. A wirelessly-controlled load controller assembly for use with a wireless switch for at least one fixture, comprising:
a junction box comprising at least one knockout; and
a load controller mounted inside the junction box, the load controller comprising:
an enclosure comprising a fitting projecting through the knockout to maintain the enclosure in fixed relation to the junction box;
a control circuit disposed within the enclosure, the control circuit including a microprocessor in communication with a wireless transceiver and an antenna, the control circuit being configured to control mains current delivered to the at least one fixture using at least one electrical wire;
an antenna port disposed within the fitting, the antenna extending through the antenna port and the knockout to an exterior of the junction box; and
at least one separate port permitting the at least one electrical wire to extend therethrough.
12. The wirelessly-controlled load controller assembly of claim 11 , wherein the junction box is metal.
13. The wirelessly-controlled load controller assembly of claim 11 , wherein the at least one fixture comprises at least one light fixture.
14. A method of mounting a wirelessly-controlled load controller assembly, the method comprising:
providing a load controller comprising:
an enclosure comprising a projecting fitting;
a control circuit disposed within the enclosure, the control circuit including a microprocessor in communication with a wireless transceiver and an antenna, the control circuit being configured to control mains current delivered to the at least one fixture using at least one electrical wire;
an antenna port disposed within the fitting, the antenna extending through the antenna port; and
at least one separate port permitting the at least one electrical wire to extend therethrough; and
mounting the load controller inside a junction box such that the projecting fitting extends through a knockout in the junction box to an exterior of the junction box, to thereby maintain the enclosure in fixed relation to the junction box, and the antenna thereby extending through the antenna port and the knockout to an exterior of the junction box.
