Abstract

A method is described for operating at least one magnetic switching element, at least one first connection of at least one sensor device being connected to at least one connection of a coil of the magnetic switching element, and the first connection or an additional connection of the sensor device being connected to a reference potential, and a measuring state being established in which at least one connection of the coil is essentially at least temporarily decoupled from the reference potential and/or from a source activating the coil, and at least one signal of at least one sensor of the sensor device being ascertained in the measuring state from at least one electrical potential at at least one connection of the coil.
