Es wird eine elektrische Schaltungsanordnung zur Schaltung eines elektrischen Verbrauchers(3), insbesondere eines Magnetventils, mittels mindestens eines dem Verbraucher (3) zugeordneten Schaltmittels (5), insbesondere eines Transistors vorgeschlagen. Die Schaltungsanordnung weist mindestens eine Auswerteschaltung auf, die mindestens einen in Reihe mitdem Schaltmittel (5) geschalteten Messwiderstand (17), mindestens ein erstes Auswertemittel (23) zur Bestimmung einer dem Kurzschlussstrom entsprechenden Größe und mindestens ein zweites Auswertemittel (25) zur Bestimmung einer dem Verbraucherstrom entsprechenden Größe umfasst. Die Schaltungsanordnung zeichnet sich dadurch aus, dass das erste Auswertemittel (23) zu dem Messwiderstand (17) parallel geschaltet ist.

The invention relates to an electric circuit configuration for switching an electrical load (3), particularly a solenoid valve, by means of at least one switching means (5) associated with the consumer (3), particularly a transistor. The circuit configuration comprises at least one analysis circuit comprising at least one measuring resistor (17) connected in series with the switching means (5), at least one first analysis means (23) for determining a parameter corresponding to the short-circuit current, and at least one second analysis means (25) for determining a parameter corresponding to the consumer current. The circuit configuration is characterized in that the first analysis means (23) is connected in parallel with the measurement resistor (17).
