Device for operating an electric locking system and / or a in the door or flap or the like built-in lock for vehicles

摘要

The invention relates to a device for actuating of an electrical locking system and / or a in the door, a flap or the like built-in lock for vehicles. In the case of such devices, at the outer side of the door or hatch a handle is arranged, the electrical components for the activation of locking functions or other functions. The functions are provided by the actuation of the sensors or switches is activated, and the signals for the control unit of a vehicle or locks to conduct. The sensors are integrated on the handle and visible and accessible from the outside and the exposed to environmental influences and exposed to large number of switching cycles. In order to avoid the sealing problems, in particular against moisture and vandalism damage, as well as in order to achieve a long service life is a piezoelectric sensor is used as a sensor.
