Zusammenfassung:	PURPOSE:To enable a window to be opened and closed even after an ignition switch is put OFF by providing a means, which holds a state of ON for a fixed time when a main switch is operated while supplying a current from a battery power supply to a drive switching means. CONSTITUTION:In case an ignition switch IG is put OFF, a current is supplied from a battery power supply BT to a supply control circuit 20 so that the current is supplied to the respective drive switching circuits 10a, 10b, 10c and 10d, when a main switch 21 is pushed to put it ON. Even thereafter the main switch 21 is put OFF, the current is supplied to a base of a transistor T20 for a fixed time during discharge of a capacitor C20. Accordingly, when any of the change-over switches 1a, 1b, 1c and 1d of the drive switching circuits 10a, 10b, 10c and 10d within a fixed time after the main switch 21 is pushed, a window can be switched. In this way, even when the window is forgotten to be closed, the window can be opened and closed without putting the ignition switch IG ON.
