An auxiliary contact system of a contactor includes an auxiliary movable contact, an auxiliary static contact corresponding to the auxiliary movable contact, and a rotation member configured to be rotatable between a first position and a second position. In the first position, a main movable contact of the contactor is driven by the rotation member to an electric contact position in which the main movable contact contacts a main static contact and the auxiliary movable contact is in the electric contact position contacting the auxiliary static contact. In the second position, the main movable contact of the contactor is driven by the rotation member to an electric separation position where the main movable contact is separated from the main static contact and the rotation member pushes the auxiliary movable contact to the electric separation position separated from the auxiliary static contact.

An electromagnetic relay includes an electromagnet, an armature configured to shift in response to a magnetic force generated by the electromagnet, a movable spring having a movable contact disposed thereon, a fixed spring including a first contact strip and a second contact strip, the first contact strip having a first fixed contact disposed thereon, the second contact strip having a second fixed contact disposed thereon, the first fixed contact and the second fixed contact facing the movable contact, and a linkage member configured to link the armature and the movable spring to shift the movable spring in conjunction with movement of the armature.

A power contactor having an electromagnetic driving unit, a rotating armature, and a reset element. The rotating armature is switched by the electromagnetic driving unit between an open position and a closed position. The reset element exerts a reset force onto the rotating armature when in the closed position.
