Patent ID: 11169209

Abstract:
The invention relates to a circuit arrangement (100) for evaluating at least two switching states of an actuating element, having a moveable contact means (110) which is connectable to the actuating element, a first evaluation circuit (140a) with a first voltage divider, which has first node points (K1a, K2a, K3a, K4a, K5a) and a first tap (150a) for tapping off a first output signal (A1, A3, A5) of the first evaluation circuit (140a), at least one second evaluation circuit (140b) with a second voltage divider, which has second node points (K1b, K2b, K3b, K4b, K5b) and a second tap (150a) for tapping off a second output signal (A2, A4, A6) of the second evaluation circuit (140b), first contact surfaces (121a, 122a, 123a, 124a, 125a) which are each electrically connected to one of the first node points (K1a to K5a), and second contact surfaces (121b, 122b, 123b, 124b, 125b) which are each electrically connected to one of the second node points (K1b to k5b), wherein via the movable contact means (110), depending on the switching state of the actuating element at least one of the first contact surfaces (121a to 125a) and/or at least one of the second contact surfaces (121b and 125b) are electrically connectable to a predetermined reference potential (P). The invention also relates to a method for operating a circuit arrangement (100), and to a switching device having a circuit arrangement (100).
