Switches can be simple, but they should never look cheap. Therefore, a great deal of experience is required to design switch haptics and acoustics in such a manner that they feel and sound the same through-out the entire vehicle interior. To meet these criteria, Preh engineers developed a control element for a multifunction steering wheel that unites five functions in only one switch, with the control snap and activation for staying the same. Another outstanding achievement of Preh`s engineers can be found in the steering wheel of the Volkswagen Passat CC. Its multi-functional switches, with an overall height of merely 12 mm, may be the flattest switches of its kind, with integrated electronics and LIN-Interface.
Since the packaging space is very limited, particularly in the case of multifunction steering wheels, very high demands are placed on the overall design. Furthermore, the switches require a first-class surface quality and uniformly narrow gaps. Preh has developed the special expertise for this in-house for many years.
