ABSTRACT:
An apparatus for controlling a window regulator connecting semiconductor switching elements which are turned ON or OFF depending on the ON-OFF state of operation switches and relay coils which are energized or de-energized depending on the ON-OFF stage of semiconductor switching elements connected to a power source through the operation switches. When the operation switches are OFF, a voltage is never applied to the semiconductor switching elements and therefore there is no fear of malfunction of semiconductor switching elements due to noise.
