Abstract

A method for detecting faults in a switch assembly includes at least one switch for monitoring the position of a component that can be moved by means of a drive which has an electric motor includes shifting the movable component from a first position to a second position spatially separated from the first position, wherein the power consumption of the electric motor changes in a previously specified manner, and wherein the switch state of the switch during a proper functioning of the switch changes in a previously specified manner, analyzing the power consumption of the electric motor and the switch state of the switch in an analysis unit, and triggering a fault action if the power consumption of the electric motor has changed in the previously specified manner and the switch state of the switch has not changed in the previously specified manner.
