Claim Text:
1. A method for producing a capacitive contact sensor having: a carrier plate made of plastic, a switching process being initiatable by touching a front surface thereof, the capacitive contact sensor further including at least one capacitive sensor electrode arranged on a rear surface of the carrier plate and capable of connection via conductor tracks to evaluation electronics, a region on the front surface of the carrier plate which lies opposite the at least one sensor electrode forming a contact zone, the method comprising: placing a plastic film carrying the at least one sensor electrode and the conductor tracks onto a first side wall of a first cavity of an injection molding tool, with the at least one sensor electrode directed toward the first side wall; injecting one selected from the group consisting of a polymethyl methacrylate and a polycarbonate for forming the carrier plate into the first cavity on a side of the plastic film facing away from the at least one sensor electrode; and performing one selected from the group consisting of the following steps (a) and (b):
