Wall-mountable wireless remote control device
A wall-mountable remote control device may be installed in place of an existing light switch and may be configured to transmit wireless signals to an electrical load device, such as a screw-in light-emitting diode (LED) lamp, to provide control of the electrical load device. The remote control device may comprise an air-gap switch adapted to be electrically coupled in series between a power source and the controllable light source, but may not comprise a bidirectional semiconductor switch for controlling the amount of power delivered to the electrical load device using a phase-control dimming technique. The remote control device may have a low-profile enclosure that is smaller than an enclosure of a standard dimmer switch, and thus may be easier to install in an electrical wallbox. The remote control device may comprise two parts including an air-gap switch device and a wireless communication device mounted to the air-gap switch device.
1. A remote-control device for controlling an electrical load device adapted to receive power from an alternating-current (AC) power source, the remote-control device comprising:
a yoke assembly physically couplable to an electrical wallbox, the yoke assembly including:
an aperture to accommodate detachable attachment of a wireless communication device that includes a plurality of user actuatable elements;
a flexible member disposed at least partially within the aperture, the flexible member to provide a biasing force against at least a portion of an external surface of the wireless communication device such that upon attachment, the flexible member retains the wireless communication device in the yoke assembly;
an adapter member physically couplable to the yoke assembly, the adapter assembly including an aperture to accommodate the passage of the wireless communication device; and
a faceplate detachably attachable to the adapter member via at least one hidden attachment feature, the faceplate including an aperture to accommodate the passage of the wireless communication device such that the plurality of user actuatable elements remains accessible.
2. The remote-control device of claim 1 , wherein the yoke assembly further comprises an air gap switch couplable in electrical series with the AC power source.
3. The remote-control device of claim 2 , wherein the air gap switch includes an actuator to open and to close the air gap switch.
4. The remote-control device of claim 3 , wherein the air gap switch actuator comprises an actuator accessible with the faceplate attached to the adapter member.
5. The remote-control device of claim 3 , wherein the air gap switch actuator comprises an actuator inaccessible with the faceplate attached to the adapter member.
6. The remote-control device of claim 1 wherein the flexible member comprises a leaf member having a surface feature to engage a complimentary surface feature when the wireless communication device is attached to the yoke assembly.
7. The remote-control device of claim 1 , further comprising the wireless communication device.
8. The remote-control device of claim 7 further comprising power supply circuitry to transfer power to the wireless communication device.
9. The remote-control device of claim 7 wherein the wireless communication device comprises wireless communications circuitry to wirelessly communicate one or more commands to remote load control circuitry to control operation of an electrical load device responsive to actuation of one or more of the plurality of user-actuatable elements.
10. The remote-control device of claim 7 wherein the wireless communication device further comprises wireless power transfer circuitry to wirelessly receive power form the power supply circuitry.
11. The remote-control device of claim 1 wherein a front surface of the wireless communication device protrudes through the faceplate when the wireless communication device is attached to the yoke assembly.
12. The remote-control device of claim 1 wherein a front surface of the wireless communication device sits flush with the faceplate when the wireless communication device is attached to the yoke assembly.
