Abstract:
A vehicular control device includes a trim member having a plurality of graphics for identifying a plurality of manual activation regions and a printed circuit board having a plurality of proximity sensors. Each of the plurality of proximity sensors generates a respective electromagnetic field within a respective manual activation region and is responsive to an object disposed in the respective manual activation region. The printed circuit board is semi-translucent and includes a plurality of illumination elements for illuminating light away from the printed circuit board. A back cover member is adaptable to the trim member for encasing the printed circuit board therebetween. A sealing member is disposed between the trim member and the back cover member. The illuminating light from the plurality of illumination elements is reflected toward the printed circuit board. The printed circuit board receives the illuminating light and diffuses the illuminating light therethrough for backlighting the plurality of graphics.
