Power window apparatus

摘要

A power window apparatus (1) includes a microcomputer (22) driving a motor in response to an input signal, a down terminal (16), an up terminal (19), and a ground terminal (18). An operation switch (10) causes a window glass to move when operated. The operation switch is connected to the microcomputer through the down terminal and the up terminal and connected to ground through the ground terminal. The operation switch generates the input signal when operated. A battery terminal (17) 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.
