Abstract
An illuminated touch switch has a touch sensitive area and a plurality of light emitting diodes arranged in a predetermined pattern. The touch switch includes a first rigid circuit board with a first electrical conductor and a second flexible circuit board with a second electrical conductor separated by a spacer of a predetermined thickness. Both conductors are aligned with the touch sensitive area and are coupled from the applied pressure providing an output signal. Light emitting diodes illuminate a single color light to indicate an enabled condition of the touch sensitive area.
