开关、电机、断路器、电热偶、电表接线图！非常齐全

这是非常齐全的一篇电工接线图的文章，包含开关接线图断路器、接触器控制回路接线图，电机逆转、正转原理接线图，电表进出接线图，电路开关接线图，电热偶接线图，希望能帮到想学这些专业的朋友，不是专业的也可以看一下懂得这些原理，以免家里电路有问题的时候出现手忙脚乱的现象，但是前提必须在安全的情况下动手去做，毕竟比较危险，电不能开玩笑的。一、开关接线图一开单控开关接线图https://p26.toutiaoimg.com/img/pgc-image/870761ea699046288e38f329e78669b5~tplv-tt-shrink:640:0.image
