Abstract

In a method for operating a magnetic switching element, at least one connection of at least one sensor device is connected to at least one connection of a coil of the magnetic switching element, and at least one measuring state is established in which the at least one connection of the coil is largely at least temporarily decoupled from a ground, a voltage source, and/or a current source activating the coil, and at least one auxiliary voltage and/or at least one auxiliary current is/are applied to the at least one connection of the coil in the measuring state, and at least one sensor signal is ascertained from at least one electrical potential, at least one potential difference, and/or at least one current flowing at the connections of the coil.
