1、交流接觸器的優(yōu)缺點(diǎn)：吸力大，吸動(dòng)可靠。由于是直接用交流驅(qū)動(dòng)的，接線簡單。不足是啟動(dòng)電流大，不適于頻繁吸合和分?jǐn)嗟膱龊?，線圈匝數(shù)少，一但被卡住極易燒毀線圈。
2、交流接觸器利用主接點(diǎn)來開閉電路，用輔助接點(diǎn)來導(dǎo)通控制回路。主接點(diǎn)一般是常開接點(diǎn)，而輔助接點(diǎn)常有兩對常開接點(diǎn)和常閉接點(diǎn)，小型的接觸器也經(jīng)常作為中間繼電器配合主電路使用。交流接觸器的接點(diǎn)，由銀鎢合金制成，具有良好的導(dǎo)電性和耐高溫?zé)g性。
直流接觸器的電磁機(jī)構(gòu)無渦流和磁滯損耗，鐵心由整塊軟鋼組成，端面上無需裝短路環(huán)，采用磁吹式滅弧裝置，線圈匝數(shù)多。直流接觸器的操作頻率較高，固有動(dòng)作時(shí)間和固有釋放時(shí)間要長。交流接觸器起動(dòng)電流大，不適于頻繁吸合和分?jǐn)嗟膱龊?，線圈匝數(shù)少。
