Abstract

A process and a device for controlling a movement of an armature of an electromagnetic switching element having an exciter coil. A first setpoint for the current can be defined after a first time. A second setpoint for the current can be defined after a second time. The second setpoint is smaller than the first setpoint. The second time also occurs before a third time at which the armature has reached its end position.
