Apparatus for electrically triggering water discharge

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.
