ABSTRACT:
Circuit arrangement for detecting the state of at least one electrical switch having at least one set input (Set1, Set2, Set3) in each case and at least one sensor output (Sensor1, Sensor2, Sensor3) in each case, each of which is allocated to an electrical switch (S1, S2, S3), wherein the sensor output (Sensor1, Sensor2, Sensor3) is connected via a first current path to a first potential if a signal with the value logic “1” is present at the set input (Set1, Set2, Set3) and is connected via a second current path to a second potential if a signal with the value logic “0” is present at the set input (Set1, Set2, Set3), and wherein a wake-up signal is generated at a wake-up signal output (wakeup) if a current which is greater than a predetermined threshold current is detected in the first or second current path.
