Abstract

A control device includes at least one button, a veneer secured to an outer surface of the button, and at least one light source configured to backlight the button. The veneer includes indicia defining an open portion exposing a portion of a body of a respective button, a floating portion, and at least one rib that suspends the floating portion. The rib has an upper surface recessed relative to a front surface of the veneer, and opposed sides extending from a base of the rib to the upper surface. The opposed sides are tapered between the base and the upper surface, such that the upper surface is narrower than the base.

Claims

1. A veneer that is configured to be attached to a control device, the veneer comprising:

a front surface;

an indicium defined through the front surface, the indicium comprising;

an open portion;

a floating portion within the open portion; and

a rib that suspends the floating portion within to the open portion;

wherein the rib comprises;

an upper surface that is recessed relative to the front surface; and

opposed sides that extend from a base of the rib to the upper surface; and

wherein the sides are configured to be tapered between the base and the upper surface such that the upper surface is narrower than the base.

2. The veneer of claim 1, further comprising:

a filler material that is disposed in the indicium.

3. The veneer of claim 1, wherein the veneer is attached to a backlit button of the control device.

4. The veneer of claim 1, wherein the veneer is attached to a backlit faceplate of the control device.

5. The veneer of claim 1, wherein the indicium is located on a flat planar portion of the front surface.

6. The veneer of claim 5, wherein the veneer is made of metal.

7. The veneer of claim 6, wherein the front surface of the veneer has a surface finish applied thereto, and

wherein the sides and the upper surface of the rib are unfinished.

8. A control device that is configured for use in a load control system for controlling an amount of power delivered to an electrical load, the control device comprising:

a button having a body that defines an outer surface; and

a veneer that is attached to the outer surface of the body, the veneer including an indicium that extends into a front surface of the veneer, the indicium defining an open portion and a floating portion;

wherein a portion of the outer surface of the body is exposed through the open portion; and

wherein the indicium includes a rib that suspends the floating portion relative to the open portion, the rib defining an upper surface that is recessed relative to the front surface of the veneer and opposed sides that extend from a base of the rib to the upper surface.

9. The control device of claim 8, wherein the veneer is attached to the body with an adhesive.

10. The control device of claim 8, wherein the indicium is a machined indicium that is cut through the veneer.

11. The control device of claim 10, wherein the sides are tapered between the base and the upper surface, such that the upper surface is narrower than the base.

12. The control device of claim 8, wherein the veneer is metal.

13. The control device of claim 12, wherein the front surface of the veneer has a surface finish applied thereto, and

wherein the sides and the upper surface of the rib are unfinished.

14. The control device of claim 8, wherein the body of the button is translucent.

15. The control device of claim 14, further comprising at least one lighting element that is configured to illuminate an inner surface of the button that is opposite the outer surface.

16. The control device of claim 14, wherein the inner surface of the body defines at least one lens feature that is configured to disperse light received from the lighting element along a portion of the outer surface.

17. A control device that is configured for use in a load control system for controlling an amount of power delivered to an electrical load, the control device comprising:

a faceplate that defines an outer surface and an opposed inner surface;

a veneer that is attached to the outer surface of the faceplate, the veneer including an indicium that extends into a front surface of the veneer, the indicium defining an open portion and a floating portion such that one or more portions of the outer surface of the faceplate are exposed; and

wherein the indicium includes a rib that suspends the floating portion relative to the open portion, the rib defining an upper surface that is recessed relative to the front surface of the veneer and opposed sides that extend from a base of the rib to the upper surface.

18. The control device of claim 17, wherein the indicium is a machined indicium that is cut through the veneer.

19. The control device of claim 17, wherein the faceplate is translucent.

20. The control device of claim 19, further comprising at least one lighting element that is configured to illuminate the inner surface of the faceplate.
