Method and device for operating a switching device

A method is disclosed for operating a switching device using at least one electromagnetic drive, which has a displaceable armature for opening and closing at least one main contact of the switching device. According to at least one embodiment of the invention, a modification of the magnetic flux between a first position, when the main contact is deactivated, and a second position, when the main contact is activated, is identified in the electromagnetic drive and a solenoid current of the electromagnetic drive is restricted to a predetermined minimum current value in the second position, if the magnetic flux modification exceeds a predeterminable value. One advantage of at least one embodiment is that an actuation displacement of the armature can be identified as reliable, if an associated modification of the magnetic flux is also measured. The metrological recording of the magnetic flux is contactless.
