Abstract

A configurable switch matrix assembly with button assembly is disclosed for keypads used in devices such as primary control points for automation systems in homes vehicles, or commercial environments. The configurable switch matrix assembly preferably includes a frame for supporting a plurality of positionable cross members and optionally a baffle. The cross members and frame each preferably include cantilevers which can be deflected by pressing the button assemblies to activate switches associated with the keypad. Dynamic status lights and back lights may provide illumination of varying colors and intensities. Button labels may be easily replaced in the button assemblies. Button assemblies of different sizes and shapes may be easily attached to the configurable switch matrix assembly in various configurations without the need for different attaching devices for each situation and/or environment.

Claims

1. A button assembly for actuating an electrical switch, said button assembly comprising:

a lens, said lens being composed of a transparent material, said lens further comprising a bottom surface;

a base, said base comprising a top surface and a bottom surface, said top surface comprising a recessed portion adapted to receive the bottom surface of the lens;

a first means for releasably coupling the lens and base together; and

a second means for releasably attaching tile button assembly to a structure;

wherein the recessed portion is further adapted to receive a label, said label being interposed between the bottom surface of the lens and the recessed portion of the top surface of the base when the lens and the base are coupled together; and

wherein the base diffuses light from a first source passing through the base.

2. The button assembly of claim 1 wherein the base further comprises a hollow passage for allowing light from a second source to pass unimpeded through the base.

3. The button assembly of claim 2 wherein the first and second light sources are capable of creating light of different colors when viewed through the lens.

4. The button assembly of claim 3 wherein the first and second light sources comprise two or more lights and wherein the different light colors are created by varying the intensity of each of the individual lights.

5. The button assembly of claim 2 wherein the first and second light sources comprise LEDs.

6. The button assembly of claim 2 wherein the first and second light sources each comprise a red, green and blue LED.

7. The button assembly of claim 2 wherein the light from the second source passes through a shroud before passing through the hollow passage on the base.

8. The button assembly of claim 1 wherein the lens and the base are composed of plastic.

9. The button assembly of claim 1 wherein the structure is a switch matrix.

10. The button assembly of claim 1 further comprising a plurality of legs disposed on the bottom surface of the base, each of the plurality of legs comprising an engagement member for releasably attaching the button assembly to a structure.

11. The button assembly of claim 10 further comprising a cross support extending between two of the plurality of legs, said cross support used to depress a plunger on the electrical switch when the button assembly is in use.

12. The button assembly of claim 1 wherein the recessed portion is further adapted to receive a label, said label being interposed between the bottom surface of the lens and the recessed portion of the top surface of the base when the lens and the base are coupled together.

13. The button assembly of claim 1 wherein the base diffuses light from a first source passing through the base when the button assembly is in use.

14. The button assembly of claim 1 wherein the base further comprises a hollow passage for allowing light from a second source to pass unimpeded though the base when the base is in use.

15. The button assembly of claim 1 wherein the button assembly is releasably attached to a switch matrix.

16. The button assembly of claim 1 wherein the lens further comprises a viewing surface, said viewing surface comprising a first region and a second region, said first region receiving light from a first light source and said second region receiving light from a second light source.

17. The button assembly of claim 16 wherein the base further comprises a hollow passage, the light from the first light source traveling primarily through the hollow passage to the first region and the light from the second light source traveling primarily through the base to the second region.

18. The button assembly of claim 17 wherein the first light source is capable of generating light of varying colors when observed by a human in the first region.

19. The buff on assembly of claim 18 wherein the first light source comprises two or more LEDs controlled by a microprocessor.

20. The button assembly of claim 17 wherein the second light source is capable of generating light of varying colors when observed by a human in the second region.

21. The button assembly of claim 20 wherein the second light source comprises two or more LEDs controlled by a microprocessor.
