Setting device for adjusting an actuator between two end points, in particular for controlling gas flow in an internal combustion engine, - with an armature that is pivotally mounted about a pivot axis between two end points in a stator and which is non-rotatably connected or connectable to the actuator, - with a restoring device for biasing the armature into a neutral point lying between the end points, - with at least one, electromagnet disposed on or in the stator for generating electromagnetic attraction forces, - with at least one first stator-side contact surface against which a first contact surface of the armature rests in the first end point of the armature, - with at least one second stator-side contact surface on which a second contact surface against which the armature rests in the second end point of the armature, - with a sensor for measuring at least one parameter of a magnetic field generated by at least one electromagnet during the operation of the setting device, depending on the armature movement and / or armature point, - wherein a control device is provided for actuating at least one electromagnet that controls the current and / or voltage supply of at least one electromagnet with the sensor system for evaluating the measured signals of the sensor system during a switching operation in which the armature moves from one, releasing end point to the other catching end point, Characterised in that - the control device is designed such that it terminates the control of the current and / or voltage supply of at least one electromagnet after a predetermined control time by means of the measured signals of the sensor system during a switching operation and that instead a constant voltage prevails across at least one electromagnet, - that the control time is such that the armature at the end of the control time has not yet reached the catching end point. - with an armature that is pivotally mounted about a pivot axis between two end points in a stator and which is non-rotatably connected or connectable to the actuator, - with a restoring device for biasing the armature into a neutral point lying between the end points, - with at least one, electromagnet disposed on or in the stator for generating electromagnetic attraction forces, - with at least one first stator-side contact surface against which a first contact surface of the armature rests in the first end point of the armature, - with at least one second stator-side contact surface on which a second contact surface against which the armature rests in the second end point of the armature, - with a sensor for measuring at least one parameter of a magnetic field generated by at least one electromagnet during the operation of the setting device, depending on the armature movement and / or armature point, - wherein a control device is provided for actuating at least one electromagnet that controls the current and / or voltage supply of at least one electromagnet with the sensor system for evaluating the measured signals of the sensor system during a switching operation in which the armature moves from one, releasing end point to the other catching end point, Characterised in that - the control device is designed such that it terminates the control of the current and / or voltage supply of at least one electromagnet after a predetermined control time by means of the measured signals of the sensor system during a switching operation and that instead a constant voltage prevails across at least one electromagnet, - that the control time is such that the armature at the end of the control time has not yet reached the catching end point.
