Abstract

An illuminated switch member assembly is disclosed. The assembly includes an applique coupled to a faceplate and substantially parallel to a circuit board such that a first light channel is defined. The assembly also includes a switch member casing coupled to the faceplate such that a second light channel is defined by the walls of the casing. And, an actuator is connected to the circuit board through a contact mechanism and to the button member casing. The assembly further includes a light filter attached to the applique and disposed between the faceplate and the circuit board such that the light filter substantially divides the first light channel from the second light channel. Furthermore, a light source is disposed within the first light channel and emanates a light. Upon activation of the assembly, the light emanates from the light source and through the first light channel and the light filter. The light subsequently reflects off a surface on the actuator such that it travels through the second light channel to illuminate the switch member.

Claims

1. An illuminated switch member assembly comprising:

an applique;

a faceplate coupled to said applique;

a circuit board substantially parallel to said applique such that a first light channel is defined;

an actuator with a surface for reflecting light, said actuator coupled to a switch member casing and connected to said circuit board through a contact mechanism;

said switch member casing moveably coupled to said faceplate such that a second light channel is defined by walls of said casing;

a first light filter having a first color coupled to said applique and disposed between said applique and said circuit board;

a light source disposed within said first light channel and emanating a light; and

a colored enclosure covering said light source, whereby said light source is supplementally filtered by said colored enclosure;

whereby said light from said light source travels through said first light channel and said first light filter and is reflected from said surface on said actuator into said second light channel to illuminate a switch member.

2. The assembly for lighting switch members as recited in claim 1 further comprising a colored resin applied to said switch member, whereby said switch member is supplementally filtered by said colored resin.

3. The assembly for lighting switch members as recited in claim 1, wherein said applique comprises a second light filter having a second color substantially different from said first color.

4. The assembly for lighting switch members as recited in claim 1, wherein said applique and said first light filter comprise a pliable poly-carbonate film.

5. An illuminated switch member assembly comprising:

an applique;

a faceplate coupled to said applique;

a circuit board substantially parallel to said applique such that a first light channel is defined;

an actuator with a surface for reflecting light, said actuator coupled to a switch member casing and connected to said circuit board through a contact mechanism;

said switch member casing moveably coupled to said faceplate such that a second light channel is defined by walls of said casing;

a first light filter having a first color coupled to said applique and disposed between said applique and said circuit board wherein said first light filter substantially divides said first light channel from said second light channel; and

a light source disposed within said first light channel and emanating a light;

whereby said light from said light source travels through said first light channel and said first light filter and is reflected from said surface on said actuator into said second light channel to illuminate a switch member.

6. An illuminated switch member assembly comprising:

an applique;

a faceplate coupled to said applique;

a circuit board substantially parallel to said applique such that a first light channel is defined;

an actuator with a surface for reflecting light, said actuator coupled to a switch member casing and connected to said circuit board through a contact mechanism,

said switch member casing moveably coupled to said faceplate such that a second light channel is defined by walls of said casing;

a first light filter having a first color coupled to said applique and disposed between said applique and said circuit board wherein said first light filter is coupled to said circuit board; and

a light source disposed within said first light channel and emanating a light;

whereby said light from said light source travels through said first light channel and said first light filter and is reflected from said surface on said actuator into said second light channel to illuminate a switch member.

7. A method of assembling a control panel case comprising:

coupling an applique to a faceplate so that said applique is substantially parallel to a circuit board such that a first light channel is defined therebetween;

slidably coupling a switch member casing to said faceplate such that a second light channel is defined therein by walls of said casing;

positioning a first light filter having a first color between a light source and the switch member so that said first light filter extends substantially across said first light channel.

8. The method of assembling as recited in claim 7, wherein positioning includes coupling said first light filter to said circuit board.

9. The method of assembling as recited in claim 7, wherein positioning includes molding an applique to said first light filter at a flexible point of contact.

10. The method of assembling as recited in claim 7, wherein positioning includes folding said first light filter from a plane of said applique.

11. The method of assembling as recited in claim 7, wherein positioning includes leveling said first light filter in relation to said applique.

12. The method of assembling as recited in claim 7, wherein said positioning step includes the step of positioning a second light filter having a second color substantially different from said first color.

13. A method for illuminating a switch member comprising:

directing light from a light source through a first light channel defined between a circuit board and an applique coupled to a faceplate;

filtering said light trough a light filter to produce filtered light;

supplementally filtering said light source through a colored enclosure covering said light source; and

reflecting said filtered light from a surface on an actuator into a second light channel within the switch member such that said filtered light emanates from the switch member.

14. The method for illuminating as recited in claim 13, wherein directing said light through a second light channel includes defining said second light channel within walls of a casing for the switch member.

15. A method for illuminating a switch member comprising:

directing light from a light source through a first light channel defined between a circuit board and an applique coupled to a faceplate;

filtering said light through a light filter to produce filtered light;

supplementally filtering the switch member through a colored resin on the switch member; and

reflecting said filtered light from a surface on an actuator into a second light channel within the switch member such that said filtered light emanates from the switch member.

16. A method for illuminating as recited in claim 15, wherein directing said light through a second light channel includes defining said second light channel within walls of a casing for the switch member.
