A contactor includes: a frame; a stationary contact; a movable contact movable between a closed position and an open position, wherein, in the closed position, the movable contact and the stationary contact are connected such that the contactor is closed, and in the open position, the movable contact and the stationary contact are disconnected such that the contactor is open; and a reset mechanism including a counter force spring, the counter force spring being a torsion spring used to bias the movable contact toward the open position, wherein the torsion spring is an integral component including a body portion having a longitudinal axis, a middle leg extending from the body portion and two torsion arms positioned at two ends of the body portion, and the torsion arms are arranged at two opposite sides of the movable contact. Also provided is an electrical control cabinet including the contactor.

Embodiments of the present disclosure provide a stationary contact assembly and a corresponding switch contact. The stationary contact assembly comprises: a stationary contact body (); a stationary contact point () placed on the stationary contact body (); and an arc-guiding member () fixed on the stationary contact body () and including an arc guiding portion (), the arc guiding portion () comprising a first end (A) and a second end (B) that are opposite to each other, the first end (A) being close to the stationary contact point (), a direction form the first end (A) to the second end (B) defining a main movement direction (F) of arc. The arc guiding portion () of the arc-guiding member () comprises an arc-guiding section () at the first end (A), the arc-guiding section is adapted to guide the arc away from the stationary contact point () into the arc guiding portion (), and the stationary contact point () is close to or in contact with the arc-guiding section () in the main movement direction (F) of the arc. The stationary contact assembly of the embodiments of the present disclosure has an improved arc-guiding member that can guide the arc to quickly leave the contact point, enhance the mechanical strength of the stationary contact and reduce the production cost of the contact.
