Abstract
An actuating and display plate for a flushing device consists of a non-conductive transparent material, wherein the plate has at least one viewing window, behind which are disposed: an infrared light source, a proximity sensor, which works on a light-reflection basis and is sensitive to the wavelength zone and with which the flushing device can be triggered, and a display light source within the visible light zone. On the plate is provided a back coating, which has a transmission in the range between 2 percent and 15 percent for the visible light zone (22) and a transmission of more than 60 percent for the near-infrared light zone (24).
