Abstract:
1. An apparatus for electrically triggering water discharge, comprising: an operating plate, at least one sensor, at least a first coating, a second coating and a third coating, and at least one light source, wherein said at least one sensor is arranged in a rearwards region, when viewed by a user triggering the water discharge, behind the operating plate, wherein said operating plate is a plate which is transmissive for light that is visible to the human eye and for near-infrared light, wherein said operating plate has at least one indication surface region on a side that is remote from the user, wherein said at least one indication surface region is provided with the first coating, said first coating being a partially transmissive coating behind which at least one light source is arranged which emits light that is visible to the human eye, wherein said operating plate has at least one signal-transmitter surface region on the side that is remote from the user, wherein said at least one signal-transmitter surface region is provided with the second coating being a coating that is partially transmissive for infrared light, behind which at least one light source, which emits light of at least one infrared wavelength, is arranged, wherein said operating plate has at least one sensor surface region on the side that is remote from the user, and wherein said at least one sensor surface region is provided with the third coating, said third coating being a coating that is partially transmissive for infrared light, behind which at least one sensor that is sensitive to infrared light is arranged.
