Abstract
Power switches are provided with measures for preventing a recommendation of the arc from the secondary current path to the main current path and/or measures for returning the current limiter during the recommutation of the light art. A corresponding arrangement for carrying out the method is provided with means in the power switch and/or current limiter for preventing a switch failure of the current limiter disposed in the secondary current path of the power switch. The current limiter can be especially a PTC current limiter.
