ABSTRACT OF THE DISCLOSURE The invention relates to a system for monitoring the closing of a door or other such barrier, such as a sliding door of a vehicle. This system has a circuit outside of the door which serves to emit a signal indicating the open or closed state of the door. In the production of this signal, the need for any electromechanical limit switches or indicating devices mounted on the door and coupled galvanically with the circuit is avoided by providing, in accordance with the invention, a circuit that is mounted on the door. Both circuits have at least one inductive element. The inductive elements are coupled only inductively with one another, but are not in physical contact with one another, so that the production of the signal indicating the open or closed state of the door can be performed contactlessly.
