The invention relates to a circuit arrangement () for evaluating at least two switching states of an actuating element, having a moveable contact means () which is connectable to the actuating element, a first evaluation circuit () with a first voltage divider, which has first node points (K, K, K, K, K) and a first tap () for tapping off a first output signal (A, A, A) of the first evaluation circuit (), at least one second evaluation circuit () with a second voltage divider, which has second node points (K, K, K, K, K) and a second tap () for tapping off a second output signal (A, A, A) of the second evaluation circuit (), first contact surfaces () which are each electrically connected to one of the first node points (Kto K), and second contact surfaces () which are each electrically connected to one of the second node points (Kto), wherein via the movable contact means (), depending on the switching state of the actuating element at least one of the first contact surfaces (to) and/or at least one of the second contact surfaces (and) are electrically connectable to a predetermined reference potential (P). The invention also relates to a method for operating a circuit arrangement (), and to a switching device having a circuit arrangement ().

Circuit arrangement for evaluating at least two switching states of an actuating element, method for operating a circuit arrangement and switching device

The invention relates to a sensor device for a vehicle for capacitively detecting input means in the region of a detection area, having a first sensor electrode and a second sensor electrode and an evaluation unit which is electrically connected to a respective first connection of the first sensor electrode and of the second sensor electrode via connection lines. The object of the invention is to provide a particularly accurate and reliable sensor device for a vehicle for capacitively detecting input means. The object according to the invention is achieved by using respective second connections on the first sensor electrode and on the second sensor electrode and by means of corresponding methods for detecting the presence of input means and for detecting faults.

The invention relates to a touch-sensitive operating device () for a motor vehicle, having an actuation lever (), in particular a steering column stalk, which has an elongate configuration, having a sensor arrangement comprising at least one touch-sensitive and/or proximity-sensitive sensor element () which is arranged on the actuation lever (), and having an electronic evaluation device which is coupled to the at least one sensor element () and is configured to detect the at least one sensor element () being touched and/or the at least one sensor element () being approached. The evaluation device is configured to identify an operating gesture of an operator on the actuation lever on the basis of a combination of at least two detected touches on the sensor arrangement and/or approaches towards the sensor arrangement, and to trigger a predetermined operating function on the basis of the identified operating gesture.
