在简述了汽车模块化技术的基础上，以模块化产品设计的原理，就公交车车门开关存在的缺陷进行模块化的设计。

This article introduces the auto modular technology, then makes modular design according to the principle of modular product design and the characteristics of bus door switch.

当门开关关闭(车门打开)的引脚电压慢慢上升8以上的三角形产生短期占空比输出波形的负峰和一个暗淡的灯光。

When the door switch is closed (car door open) the voltage on pin 8 slowly rises above the negative peaks of the triangle wave producing a short duty cycle output and a dim light.
