1. A motor vehicle door latch mechanism, comprising:
a circuit arrangement with at least one sensor (9, 10, 11, 12) and with two different, connected control units (6, 7), wherein the sensor (9, 10, 11, 12) has two or more switch states, and wherein the two different control units (6, 7) are connected to the sensor (9, 10, 11, 12), wherein the sensor (9, 10, 11, 12) contains a switch (9), and one control unit (7) is connected to two parallel, central current paths (10, 11) of a cable network (10, 11, 12), with one current path (11) containing the switch (9), and an other control unit (6) is connected to the switch (9) via a third, additional current path (12) of the cable network (10, 11, 12), wherein all current paths (10, 11, 12)of the cable network (10, 11, 12)contain different electrical resistors (R1, R2), corresponding to the respective varying current in the individual current path (10, 11, 12), with the supply voltage being mainly constant, and wherein the two, central current paths (10, 11) belonging to the control unit (7) and the third, additional current path (12) belonging to the other control unit (6) are separated from each other by an electronic separator element (D).
