Abstract
A circuit arrangement for activating a control device includes: a first switch in a main current path, via which the control device is activated; an alternative current path; and a control logic which compares a voltage present for activating the control device to a threshold voltage and opens the first switch if the threshold voltage falls below so that a higher volume of an interference current effectuated by the present negative voltage flows via the alternative current path.
