Contactor

The utility model discloses a contactor. The contactor comprises an insulating shell which is provided with an inner cavity forming an arc extinguish chamber; the pair of static terminals are fixed to the insulating shell and extend into the arc extinguish chamber; the movable terminal is arranged in the arc extinguish chamber and is used for bridging the pair of static terminals; the first magnetizer is arranged in the arc extinguish chamber and is fixed relative to the insulating shell; the second magnetizer is assembled with the movable terminal so as to move synchronously with the movable terminal; the pair of static terminals and the first magnetizer are arranged right above the movable terminal, and the first magnetizer and the second magnetizer are opposite in the vertical direction. According to the utility model, when short-circuit current flows through the moving terminal and the static terminal, the first magnetizer and the second magnetizer are magnetized by a magnetic field generated by the short
