交流接觸器利用主接點來控制電路，
用輔助接點來導通控制回路。
主接點一般是常開接點，而輔助接點常有兩對常開接點和常閉接點，小型的接觸器也經常作為中間繼電器配合主電路使用。
交流接觸器的接點，由銀鎢合金制成，具有良好的導電性和耐高溫燒蝕性。
交流接觸器動作的動力源于交流通過帶鐵芯線圈產生的磁場，電磁鐵芯由兩個「山」字形的幼硅鋼片疊成，其中一個固定鐵芯，套有線圈，工作電壓可多種選擇。為了使磁力穩定，鐵芯的吸合面加上短路環。交流接觸器在失電后，依靠彈簧復位。

電路的裝置，所以經常運用于電動機做為控制對象﹐也可用作控制工廠設備﹑電熱器﹑工作母機和各樣電力機組等電力負載，接觸器不僅能接通和切斷電路，而且還具有低電壓釋放保護作用。接觸器控制容量大，適用于頻繁操作和遠距離控制,是自動控制系統中的重要元件之一。
在工業電氣中，接觸器的型號很多，工作電流在5A-1000A的不等，其用處相當廣泛
