Abstract
A cover plate (5) for use with an electrical supply. In one embodiment, the backlit cover plate comprises a plate (5), the plate (5) including a window (15) therein; and backlighting, the backlighting powered by the electrical supply (55), the backlighting (20) disposed to be mounted on the plate (5) so as to shine through the window (15). Optional labels (45) may be provided through which the backlighting may shine, thereby illuminating data on the labels (45) from behind. In a disclosed embodiment, the backlighting (20) comprises electroluminescent lighting.
Claims17
An electrical service cover plate for use with an electrical power supply comprising:
- a plate, including a window therein and an opening in the plate for receiving a throw of a switch having an operating mechanism to alternatively connect or disconnect the electrical power supply in said opening;
- a backlight, selectively energized by the electrical power supply when the switch interrupts the power supply, mounted on a posterior of said plate so as to illuminate the window when energized;
- and
- a label disposed between the window of said plate and said backlight, said label providing a translucent background and an opaque foreground displaying data to be communicated.
An electrical service cover plate for use with an electrical power supply comprising:
- a plate, the plate including a window therein and an at least one opening, an electrical outlet receptacle receivable in said at least one opening;
- a backlight, energized by the electrical power supply when power is being supplied to the receptacle, mounted on the posterior of said plate so as to illuminate the window when power is being supplied to the receptacle;
- and
- a label disposed between said plate and said backlight, said label providing a translucent background and an opaque foreground displaying data to be communicated.
An electrical service switch cover for use with an electrical power supply comprising:
- a plate having a window, an opening for the throw of a switch, and one or more holes for the attachment of the plate to a surface;
- a backlight connected to a posterior of the plate covering the window in the plate;
- a label disposed between said plate and said backlight, said label providing a translucent background and an opaque foreground displaying data to be communicated;
- and
- electrodes on the backlight for connecting the backlight to a pair of electrical service connectors of the switch to energize the backlight when the switch is off.
An electrical service outlet cover for use with an electrical power supply comprising;
- a plate having a window, one or more openings for electrical service receptacles, and one or more holes for the attachment of the plate to a mounting surface;
- a backlight connected to a posterior of the plate covering the window in the plate;
- a label disposed between said plate and said backlight, said label providing a translucent background and an opaque foreground displaying data to be communicated;
- and
- electrodes on the backlight for connecting the backlight to a pair of electrical service connectors of the outlet receptacles to energize the backlight.
A method for mounting a backlit electrical cover plate to permit identification of and the status of the electrical power to an electrical service point comprising the steps of;
- connecting a first conductor of a backlight to the load leg of the electrical service outlet;
- connecting a second conductor of a backlight to the common leg of the electrical service outlet;
- and
- attaching the cover plate to the surface adjacent the electrical service point.
