The present invention discloses a contactor. The contactor comprises of: an insulation outer housing (20); a pair of static terminals (2) which is provided in the insulation outer housing (20) and stationary relative to the insulation outer housing (20); a movable terminal (1) which is provided in the insulation outer housing (20) and movable between a closed position in contact with the static terminal (2) and an opened position separated from the static terminal (2); a first magnetic conductor (3) which is fixed to the movable terminal (1) to move synchronously with the movable terminal (1); a static bracket (5) which is provided in the insulation outer housing (20) and stationary relative to the insulation outer housing (20); a second magnetic conductor (4) which is movably provided in the static bracket (5); and an elastic member (6) which is provided between the static bracket (5) and the second magnetic conductor (4). The second magnetic conductor (4) and the static terminal (2) are arranged at the same side of the movable terminal (1), and the second magnetic conductor (4) is floatable supported in the static bracket (5) by the elastic member (6), so that the distance between the first magnetic conductor (3) and the second magnetic conductor (4) is inversely proportional to the current flowing through the movable terminal (1) and the static terminal (2). The present invention not only improves the ability of the contactor to withstand the short circuit current, but also does not affect the normal connection and disconnection operation of the contactor.
