する第２スイツチ手段と、を備えたことを特徴と
するパワーウインドのスイツチ回路。 A changeover switch that opens and closes the window by rotating the motor in the forward and reverse directions by switching the operation knob, a solenoid that holds the operation knob of the changeover switch in the operating position, and two resistors connected in series to both ends of the motor. The first one turns on by detecting the voltage at the point.
a switch means, one input terminal is connected between two dividing resistors connected in series to the motor power supply via the first switch means, and the other input terminal is connected to a current connected in series with the motor. A power window switch circuit comprising: a comparator connected to a motor side of a detection resistor; and second switch means for turning on and off the solenoid based on a signal from the comparator.
