ABSTRACT:
An electrically illuminated folded card device formed from sheet stock, for use as a greeting card or the like. A first portion of the sheet stock forms a display panel having one or more apertures. LED's disposed behind the display panel provide illumination through the apertures. A printed circuit board is mounted behind the display panel; LED's are, in turn, mounted on the board. A portion of the sheet stock forms a tab disposed behind the display region. A slide switch is formed by a pair of conductive foil areas on the printed circuit board and a conductive shorting member is attached to the tab. As the card is opened, the tab translates behind the display panel and the shorting member wipes across the pair of foil areas, to complete the circuit between the battery and lamps, to turn on the LED's.
