Abstract

A remote control device may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may include a control unit and a base for the control unit. The base may include a frame and a mounting tab that attaches to the paddle actuator of a mechanical switch. The mounting tab may be monolithic with the frame. Alternatively, the base may include a resilient attachment member that extends from the frame and is captively retained by the mounting tab. The frame and the attachment member may be configured such that the attachment member is held in a fixed in position by the frame, or such that the attachment member is translatable relative to the frame. The base may include one or more alignment members. The base may cause a rear surface of the frame to be biased against the mechanical switch.

First claim

The invention claimed is:

1. A base configured to be attached to a paddle actuator of an installed mechanical switch, wherein the installed mechanical switch controls whether power is delivered to an electrical load, the base comprising:
a mounting tab that is configured to be attached to a protruding portion of the paddle actuator, the protruding portion projecting outward when the installed mechanical switch is operated into a position that causes power to be delivered to the electrical load; and
a frame that defines an opening that is configured to receive the protruding portion of the paddle actuator therein, wherein, when the protruding portion is received in the opening, the frame at least partially surrounds the paddle actuator,
wherein the mounting tab and the frame are configured to, when the base is attached to the paddle actuator, cause a rear surface of the frame to be biased against a structure that surrounds the paddle actuator.

2. The base of claim 1 , wherein the mounting tab is monolithic with the frame.

3. The base of claim 2 , wherein the mounting tab defines an attachment surface that is angularly offset relative to the rear surface of the frame.

4. The base of claim 3 , wherein the mounting tab defines a fixed end that is supported by the frame, the mounting tab extending outward from the fixed end to a free end.

5. The base of claim 3 , wherein the frame comprises an outer wall that extends along a perimeter of the frame, and further comprises a cross member that extends between opposed side walls of the outer wall, and wherein the mounting tab extends outward from the cross member.

6. The base of claim 3 , wherein the protruding portion of the paddle actuator defines an actuation surface that forms a first angle relative to the structure of the installed mechanical switch that surrounds the paddle actuator, and
wherein the attachment surface forms a second angle relative to the rear surface of the frame that is smaller than the first angle.

7. The base of claim 1 , further comprising:
a resilient attachment member that extends from the frame and that is configured to engage with the mounting tab.

8. The base of claim 7 , wherein the mounting tab is configured to receive and captively retain the resilient attachment member.

9. The base of claim 8 , wherein the resilient attachment member comprises a first portion that is supported by the frame and a second portion that defines a tab that extends outward from the first portion, and
wherein the mounting tab defines a channel that is configured to receive the tab therein.

10. The base of claim 9 , wherein the resilient attachment member is supported by the frame such that the resilient attachment member is translatable relative to the frame.

11. The base of claim 9 , wherein the resilient attachment member is supported by the frame such that the first portion is fixed in position relative to the frame.

12. The base of claim 9 , wherein the protruding portion of the paddle actuator defines an actuation surface that forms a first angle relative to the structure of the installed mechanical switch that surrounds the paddle actuator, and
wherein the tab extends from the first portion at a second angle relative to the rear surface of the frame that is smaller than the first angle.

13. The base of claim 1 , wherein the mounting tab defines an attachment surface that is configured to be secured to the paddle actuator.

14. The base of claim 13 , wherein the attachment surface is configured to be secured to the paddle actuator using a double-sided adhesive.

15. The base of claim 1 , further comprising at least one alignment member that extends from the rear surface of the frame, the at least one alignment member configured to be received in a gap that is defined between the structure of the installed mechanical switch that surrounds the paddle actuator and a faceplate opening that extends through a faceplate that is attachable to a yoke of the mechanical switch.

16. The base of claim 1 , wherein the structure comprises a bezel of the installed mechanical switch.

17. The base of claim 1 , wherein the structure comprises a faceplate that is attachable to a yoke of the installed mechanical switch.

18. The base of claim 1 , wherein the frame is configured for releasable attachment of a control unit to the frame.

19. The base of claim 18 , wherein the frame is further configured to receive a battery for powering the control unit.

20. The base of claim 19 , further comprising:
a printed circuit board that is configured to, when the control unit is attached to the frame, electrically couple the control unit to the battery.

21. A remote control device for use in a load control system, the remote control device configured to be mounted over an installed mechanical switch, wherein the installed mechanical switch controls whether power is delivered to an electrical load, the remote control device comprising:
a mounting tab that is configured to be attached to a protruding portion of a paddle actuator of the installed mechanical switch, the protruding portion projecting outward when the installed mechanical switch is operated into a position that causes power to be delivered to the electrical load;
a frame that defines an opening that is configured to receive the protruding portion of the paddle actuator therein, wherein when the protruding portion is received in the opening, the frame at least partially surrounds the paddle actuator; and
a control unit that is configured to be attached to the frame, the control unit including a control interface and a wireless communication circuit, the control unit configured to translate a user input from the control interface into a control signal that controls a load control device, the control unit further configured to cause the wireless communication circuit to transmit the control signal,
wherein the mounting tab and the frame are configured to, when the remote control device is mounted over the installed mechanical switch, cause a rear surface of the frame to be biased against a structure that surrounds the paddle actuator.

22. The remote control device of claim 21 , wherein the mounting tab is monolithic with the frame.

23. The remote control device of claim 22 , wherein the mounting tab defines an attachment surface that is angularly offset relative to the rear surface of the frame.

24. The remote control device of claim 23 , wherein the mounting tab defines a fixed end that is supported by the frame, the mounting tab extending outward from the fixed end to a free end.

25. The remote control device of claim 23 , wherein the frame comprises an outer wall that extends along a perimeter of the frame, and further comprises a cross member that extends between opposed side walls of the outer wall, and wherein the mounting tab extends outward from the cross member.

26. The remote control device of claim 23 , wherein the protruding portion of the paddle actuator defines an actuation surface that forms a first angle relative to the structure of the installed mechanical switch that surrounds the paddle actuator, and wherein the attachment surface forms a second angle relative to the rear surface of the frame that is smaller than the first angle.

27. The remote control device of claim 21 , further comprising:
a resilient attachment member that extends from the frame and that is configure
