Abstract

A device for checking the switching state of an electrical commutator, preferably coupled to the door locking means of a central locking system in a motor vehicle, has a voltage source (15) that applies two different voltage potentials to the commutator inputs (11, 12), a commutator load circuit (16) connected to the output (13) of the commutator that receives current pulses at a switching frequency (fS) via the commutator (10), and a sensing and holding circuit (21) connected to the output (13) of the commutator that senses the voltage potential at the commutator output (13) with the sensing frequency (fT) and supplies the sensed value to an evaluating unit (22) until the next sensing operation. The switching and sensing frequencies (fS, fT) are mutually synchronised. The evaluating unit (22) converts the sensed values into signals characterising the switching state.
