Abstract

A switching device has an electromagnetic switching element and a controller, the switching element including two coils on one core which act on a shared armature. In order to implement an operation of the armature to be activatable as rapidly and simply as possible with low power consumption, the controller is designed to have a switch in the current path of the coil in each case to activate each coil.
