Capacitive proximity switch

摘要

A motor vehicle (1) has a circuit structure for locking/unlocking a door lock (2) with an electronic activating circuit and capacitive proximity switch (CPS). A responsive electrode and a compensating electrode for the CPS are integrated in a door handle (4). A measurement value corresponding to a change in capacity is compared with a switch threshold to create a switching signal. An independent claim is also included for a method/device for.
