A window opening and closing control device (100,200,300) in which an other-seat unit (2,3,4) is controlled from a driver seat unit (1) via a single signal line (SL) is made. The driver seat unit (1) and the other-seat unit (2,3,4) are connected by the single signal line (SL). A direction of a current passed through a motor (23,33,43) is switched using contacts (SW1 to SW6) of a window opening switch (21 D) and a window closing switch (21 U) in the other-seat unit (2,3,4). When a window closing manipulation is performed by the driver seat unit (1), the current is passed through a coil (X2) of a relay (22B) via the contacts (SW4 to SW6) of the window closing switch (21 U), and a contact (Y2) of the relay (22B) is switched to pass a forward current through the motor (23,33,43). When a window opening manipulation is performed by the driver seat unit (1), the current is passed through a coil (X1) of a relay (22A) via the contacts (SW1 to SW3) of the window opening switch (21 D), and a contact (Y1) of the relay (22A) is switched to pass a reverse current through the motor (23,33,43). |
