摘要:
A light bar proximity switch is provided that includes a light pipe having a first surface and a second surface, wherein the first and second surface define an area. The light bar proximity sensor further includes an at least partially reflective surface adjacent the second surface, at least one circuit board spaced from the light pipe and the at least partially reflective surface, at least one proximity sensor electrically connected to the at least one circuit board, and at least one light source configured to project light along the area, wherein the emitted light is reflected by the at least partially reflective surface and viewed through the first surface.
