ABSTRACT:
Apparatus for an electrically moved sliding window, used illustratively in automotive applications, having first a built-in safety device, for providing a signal whenever the window has been raised or lowered to a preselected height and second a proximity detector is described. The proximity detector comprises a conductive strip constituting a capacitive pickup running along on a surface of the window and its upper edge. The pickup is connected to a control circuit by a conductive line which runs vertically along a side edge of the window and, more particularly, positioned at a predetermined distance inward from the side edge of the window. A plurality of vertical conducting lines, used for switching and height sensing purposes, runs vertically on the surface of the window and, more particularly, in the space between the side edge and the conductor which runs to the pickup.
