为了标明各个按钮的作用，避免误操作，通常将按钮帽做成不同的颜色，以示区别，其颜色有红、绿、黑、黄、蓝、白等。如，红色表示停止按钮，绿色表示起动按钮等。按钮开关的主要参数、型式、安装孔尺寸、触头数量及触头的电流容量，在产品说明书中都有详细说明。按钮开关有很多种，接线的方式也不统一，会各种各析产情况发生。下面呢，是小编总结的几个经常遇到的按钮开关接线的问题，大家可以来学习，指正。带灯的按钮开关怎么接线，按钮上一共有五个接线柱，现在只能测出怎么接电源线，但是灯怎么亮不知怎么接。

　　因RS485接口具有良好的抗噪声干扰性，较长的传输距离和多站能力等上述优点就使其成为的串行接口。因为RS485接口组成的半双工网络，一般只需二根连线，所以RS485接口均采用屏蔽双绞线传输。尤其适用于计算机集散控制系统。
