接点一般是常开接点，而辅助接点常有两对常开接点和常闭接点，小型的接触器也经常作为 配合主电路使用。

交流接触器的接点，由银钨合金制成，具有良好的导电性和耐高温烧蚀性。

交流接触器动作的动力源于交流通过带铁芯线圈产生的磁场， 芯由两个「山」字形的幼硅钢片叠成，其中一个固定铁芯，套有线圈，工作电压可多种选择。为了使磁力稳定，铁芯的吸合面加上短路环。交流接触器在失电后，依靠弹簧复位。

另一半是活动铁芯，构造和固定铁芯一样，用以带动主接点和辅助接点的闭合断开。

20A以上的接触器加有灭弧罩，利用电路断开时产生的电磁力，快速拉断电弧，保护接点。

The contact is generally a normally open contact, and the auxiliary contact is usually two pairs of normally open contact and normally closed contact, and the small contactor is often used as a cooperation with the main circuit.

The contact of the AC contactor is made of silver tungsten alloy, which has good electrical conductivity and high temperature ablation resistance.

The power of the action of the AC contactor comes from the magnetic field generated by the AC through the coil with an iron core. The core is composed of two young silicon steel sheets in a "mountain" shape. One of the fixed iron core is covered with a coil and the operating voltage can be selected. In order to stabilize the magnetic force, a short circuit ring is added to the suction surface of the iron core. After the AC contactor loses power, it relies on the spring to reset.

The other half is a movable core, which is constructed like a fixed core to drive the closing and disconnecting of the main and auxiliary contacts.

The contactor above 20A is equipped with an arc extinguishing cover, which uses the electromagnetic force generated when the circuit is disconnected to quickly break the arc and protect the contact.
