Zusammenfassung:	A multifunctional pushbutton switch for a vehicle steering wheel has a plurality of pushbutton switching units that have pushbutton surfaces located close to each other in a shared operating surface. The switch has a shared switch housing (20) in which actuation tappets (28,30) of the pushbutton switching units are movably guided, and a cap (10) mounted over the actuation tappets (28,30) and onto the switch housing (20). The cap (10) is made by means of a two-component injection-molding technique and consists of a relatively rigid plastic frame (12) with recessed windows (14) each of a shape and size that corresponds to the circumference of one of the pushbutton surfaces and of a silicone membrane (16) extending over the recessed windows.
