A method and device for switching an inductor are described. A first terminal of the inductor may be connected to ground via a first switching device. A second terminal of the inductor is always connected to a voltage power supply. A second inductor may be connected to ground via a second switching device. The energy released in the second inductor when the current flow is interrupted is used to switch the first inductor.

Adjustable voltage divider produced by hybrid technology

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.

Process for controlling a movement of an armature of an electromagnetic

A method and an apparatus for controlling an electromagnetic switching member having an excitation winding and a movable armature. A first time point and a second time point define a time window. Within the time window, the current characteristic and/or the voltage characteristic is evaluated in order to detect a switching time point at which the armature reaches a new limit position. The time window is enlarged if no reliable switching time point was detected within the time window.
