欧姆龙MY2NJ，电磁继电器的工作原理。
电磁继电器的工作原理
电磁式继电器一般由铁芯、线圈、衔铁、触点簧片等组成的。只要在线圈两端加上一定的电压，线圈中就会流过一定的电流，从而产生电磁效应，衔铁就会在电磁力吸引的作用下克服返回弹簧的拉力吸向铁芯，从而带动衔铁的动触点与静触点（常开触点）吸合。当线圈断电后，电磁的吸力也随之消失，衔铁就会在弹簧的反作用力返回原来的位置，使动触点与原来的静触点（常闭触点）吸合。这样吸合、释放，从而达到了在电路中的导通、切断的目的。对于继电器的「常开、常闭」触点，可以这样来区分：继电器线圈未通电时处于断开状态的静触点，称为「常开触点」；处于接通状态的静触点称为「常闭触点」。■额定值
