PURPOSE:To make it impossible to open and close a power window due to the mischief of a child by turning a push-button switch and a power window switch on so as to optionally enable the opening and closing of the power window even when an ignition switch is off. CONSTITUTION:A series circuit of a push-button switch 19 and a coil 21 of a relay 20 is connected via a circuit breaker 18 in parallel to an ignition switch 3. Moreover an ever-closed contact 22 of a relay 20 is connected to the output side of the ignition switch 3 via a circuit breaker 23, an ever-opened contact 24 is connected to the input side of the ignition switch 3 via a circuit breaker 18, and a movable contact 25 of the relay 20 is connected to a power window switch 10. This enables the movable contact 25 of the relay 20 to contact the ever-opened contact 24 by closing the push-button switch 19 and enables the power window switch 10 to function even when the ignition switch 3 is off. |
