以下是简单接触器的介绍，如想咨询ESMD371L4TXA皇冠信誉，拨打我公司专业销售人员的电话。
接触器原理******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，产生的磁场使静铁心产生电磁吸力吸引动铁心，
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。
接触器作用======接触器主要用于频繁接通或分断交、直流电路，具有控制容量大，可远距离操作，配合继电器可以实现定时操作，联锁控制，
各种定量控制和失压及欠压保护，广泛应用于自动控制电路，其主要控制对象是电动机，也可用于控制其它电力负载，如电热器、照明、电焊机、
电容器组等。
