Abstract
The invention in certain embodiments relates to a control circuit for an electric-motor-operated window lifter () of a motor vehicle (), the control circuit having a first switch () for opening a vehicle window (), a second switch () for closing the vehicle window (), and a control device (), which, when one of the switches () is activated, actuates the window lifter () to move the vehicle window () in the opening direction or closing direction. The control device () monitors the lighting current (I) which flows across a lighting element () for the switches (), and generates a control signal (I), if appropriate, for opening the vehicle window () if the lighting current (I) exceeds an overcurrent threshold value (I) thereby detecting inundation of the vehicle.
