接触器的工作原理是：当接触器线圈通电后，线圈电流会产生磁场，
产生的磁场使静铁芯产生电磁吸力吸引动铁芯，并带动交流接触器点动作，常闭触点断开，常开触点闭合，两者是联动的。当线圈断电时，电磁吸力消失，衔铁在释放弹簧的作用下释放，使触点复原，常开触点断开，常闭触点闭合。直流接触器的工作原理跟温度开关的原理有点相似。

直流电流与交流电流相比较，不存在周期性的电流数值过零点，因此，传统接触器开断电路时，触头之间产生的电弧较为强烈，燃弧时间也比较长，以便充分释放电路中剩余的能量。电弧的燃烧产生高温和强光，对触头表面有严重的烧蚀作用，触头材料在多次开断之后逐渐流失，触头电磨损严重时，导致直流接触器报废，不能开断电路。 [1] 
电力电子技术得以迅猛发展，人们将电力电子元件应用到直流接触器中，巧妙的创造出一种混合式直流接触器，使得直流接触器向智能化、可控化迈进了新的一步。这种混合式接触器利用传统直流接触器在闭合导通状态下触头接触电阻小、导通压降小的优点，将由反并联晶闸管和控制模块单元共同组成的无触点开关并联在传统直流接触器触头上。这种无触点的电力电子开关分断电路时不产生电弧，这就避免了传统接触器中电弧对触头材料的电磨损，也就大大增加了触头的使用寿命和可靠性。 [1]
