摘要： A method of recognizing the contact of an armature in an electromagnetic actuator for activating a setting member that can be brought out of a first set position, counter to the force of a restoring spring, and brought into contact with the pole surface of the electromagnet and held when the electromagnet is supplied with current. The controlled (clocked) current course for the holding phase is detected during the time provided for armature contact, and is converted into a current-proportional voltage, and the converted voltage is differentiated and detected as a recognition signal, both for the normal condition of "armature in contact" and the fault condition of "armature is not in contact."
