Abstract

In one embodiment, a system may include an electrical device having an indicator light source, an actuator having a window, a viewing piece arranged to be visible through the window, and a light guide arranged to guide light from the light source to the viewing piece. The viewing piece may have a receiving portion arranged to receive light from the light guide, and the width of the receiving portion may be substantially larger than the width of the light guide. In another embodiment, a system may include an electrical device having a first support member, and an actuator having a second support member. The actuator may be adapted to move along a path of motion from a retracted position to an extended position, and the first and second support members may be adapted to support the actuator in the extended position with forces that are substantially balanced along the path of motion.

Claims

1. A system comprising:

an electrical device having an indicator light source;

an actuator having a window;

a viewing piece arranged to be visible through the window; and

a light guide separate from the viewing piece arranged to guide light from the light source to the viewing piece;

where the viewing piece has a receiving portion arranged to receive light from the light guide; and

where the width of the receiving portion is substantially larger than the width of the light guide.

2. The system of claim 1 where the viewing piece is attached to the actuator.

3. The system of claim 1 where the viewing piece is attached to the electrical device.

4. The system of claim 1 where:

the electrical device includes a plurality of indicator light sources and a plurality of light guides arranged to guide light from the light sources to the viewing piece;

the viewing piece has a plurality of receiving portions arranged to receive light from the light guides; and

the widths of the receiving portions are substantially larger than the widths of the corresponding light guides.

5. The system of claim 1 where the receiving portion of the viewing piece comprises a polished surface.

6. The system of claim 1 where:

the viewing piece has a front surface; and

at least a portion of the front surface is one selected from the group consisting of textured and concave.

26. The system of claim 1 wherein the viewing piece and the light guide are separated by a gap and causes the light to form a light pattern wider than the light guide.

27. The system of claim 4, wherein the multiple light guides having separators between them.

7. An interchange kit comprising:

a frame adapted to be removably attached to an electrical device having an indicator light source;

an actuator movably mounted to the frame; and

a viewing piece attached to the actuator;

where the viewing piece has a receiving portion arranged to receive light from the indicator light source through an emitting area of a light guide on the electrical device, wherein the viewing piece is separate from the emitting area; and

where the area of the receiving portion is substantially larger than the emitting area.

8. The interchange kit of claim 7 where

the viewing piece has a front surface;

and

at least a portion of the front surface is one selected from the group consisting of textured and concave.

9. The interchange kit of claim 7 where:

the electrical device includes a plurality of indicator light sources;

the viewing piece has a plurality of receiving portions arranged to receive light from the indicator light sources through a plurality of emitting areas on the electrical device; and

the viewing piece is arranged to allow substantial overlap between light patterns from adjacent emitting areas.

10. The interchange kit of claim 7 where the receiving portion of the viewing piece has a substantially flat surface.

11. A system comprising:

an electrical device having a first support member extending from a surface of the electrical device; and

a paddle actuator having a second support member;

where the paddle actuator is adapted to pivot along a path of motion from a retracted position to an extended position; and

where the first and second support members are adapted to support the paddle actuator in the extended position with forces that are substantially balanced along the path of motion.

12. The system of claim 11 where:

one of the support members comprises a sliding finger; and

the other support member comprises a pair of support fingers arranged to engage the sliding finger on opposite sides of the sliding finger.

13. The system of claim 12 where:

the sliding finger comprises two opposing sloped surfaces; and

each of the support fingers comprise a sloped surface arranged to engage one of the sloped surfaces of the sliding finger when the paddle actuator is in the extended position.

14. The system of claim 13 where:

the sliding finger comprises two additional sloped surfaces; and

each of the support fingers comprise an additional sloped surface arranged to engage one of the additional sloped surfaces of the sliding finger to hold the paddle actuator in the retracted position.

15. The system of claim 11 where the first and second support members are adapted to hold the paddle actuator in the retracted position.

16. The system of claim 11 where the paddle actuator is arranged to actuate a switch when the actuator is in the extended position.

17. The system of claim 16 where the switch comprises an air gap switch.

18. An interchange kit comprising:

a frame adapted to be removably attached to an electrical device; and

a paddle actuator pivotally mounted in the frame and adapted to rotate from a retracted position to an extended position;

where the paddle actuator includes a support member adapted to engage a corresponding support member on the electrical device; and

where the support member on the paddle actuator includes opposing surfaces adapted to engage corresponding surfaces on the corresponding support member of the electrical device to support the actuator in the extended position using symmetric forces.

19. The interchange kit of claim 18 where the paddle actuator is adapted to be removably mounted in the frame.

20. The interchange kit of claim 18 where one of the support members comprises a sliding finger having an enlarged end portion.

21. The interchange kit of claim 20 where the enlarged end portion has a diamond-shaped cross section.

22. An electrical device comprising:

a housing arranged to enclose one or more electrical components;

an indicator light source;

a face portion having an aperture to enable light from the indicator light source to pass through the face portion; and

a light guide arranged to guide light from the indicator light source to the aperture;

where the housing has a footprint on a mounting plane; and

where at least a portion of the aperture is located outside of the footprint of the housing.

23. The electrical device of claim 22 where the light guide includes:

a first portion having an axis aligned with the indicator light source; and

a second portion having an axis offset from the first axis and aligned with the aperture.

24. The electrical device of claim 23 where the light guide further includes a third portion arranged to guide light from the first portion to the second portion.

25. The electrical device of claim 24 where the light guide further includes:

a first reflecting surface arranged to direct light from the first portion to the third portion; and

a second reflecting surface arranged to direct light from the third portion to the second portion.
