Abstract
A power window apparatus includes an operation switch for causing a window glass to move when operated. The operation switch generates an input signal having a ground level when operated. A microcomputer drives a motor in response to an input signal. A down terminal and an up terminal are used to connect the operation switch and the microcomputer to each other. A ground terminal is used to connect the operation switch and ground to each other. A battery terminal is used to connect the operation switch and a power supply to each other. When operated, the operation switch connects the down terminal or the up terminal to the ground terminal and generates an input signal having the ground level in the down terminal or the up terminal. When not operated, the operation switch connects the down terminal and the up terminal to the power supply terminal.
