Abstract
A multifunctional pushbutton switch for a vehicle steering wheel has a plurality of pushbutton switching units with pushbutton surfaces that are close to each other in a common operating surface. The switch has a common switch housing in which actuation tappets of the pushbutton switching units are movably guided. A cap is mounted onto the switch housing. The cap is made by means of a two-component injection-molding technique of a relatively rigid plastic frame with a cutout window whose shape and size correspond to the circumference of a pushbutton surface and of a silicone membrane stretched over the window.
