什么是主令开关？

S+B主令电器主要用于切换控制电路，通过它来发出指令或信号以便控制电力拖动系统及其它控制对象的起动.运转.停止或状态的改变。根据被控制线路的多少和电流的大小,主令电器可以直接控制,也可以通过中间继电器进行间接控制。
　　主令电器按其功能分为五类:
　　1.控制按钮
　　2.转换开关
　　3.行程开关
　　4.主令控制器
S+B主令控制器(又称主令开关)主要用于电气传动装置中,按一定顺序分合触头,达到发布命令或其它控制线路联锁.转换的目的。按其结构型式可分为凸轮调整式和凸轮非调整式主令控制器两种,其动作原理与转换开关相同,都是靠凸轮来控制触头系统的关合。不同形状凸轮的组合可使触头按一定顺序动作,而凸轮的转角是由控制器的结构决定的,凸轮数量的多少则取决于控制线路的要求。
