电磁继电器是利用电磁铁控制工作电路通断的开关.
(1)结构：电磁继电器的主要部件是电磁铁A、衔铁B、弹簧C和动触点D、静触点E.(如图所示)
(2)工作电路可分为低压控制电路和高压工作电路两部分，低压控制电路包括电磁继电器线圈(电磁铁A)，低压电源E1，开关S;高压工作电路包括高压电源E2，电动机M，电磁继电器的触点D、E部分.
(3)工作原理——闭合低压控制电路中的开关S，电流通过电磁铁A的线圈产生磁场，从而对衔铁B产生引力，使动、静触点D与E接触，工作电路闭合，电动机工作;当断开低压开关S时，线圈中的电流消失，衔铁B在弹簧C的作用下，使动、静触点D、E脱开，工作电路断开，电动机停止工作.[1]
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）释放。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”。
①控制电路的电源电压，能提供的最大电流；
②被控制电路中的电压和电流；
③被控电路需要几组、什么形式的触点。选用继电器时，一般控制电路的电源电压可作为选用的依据。控制电路应能给继电器提供足够的工作电流，否则继电器吸合是不稳定的。
