Using the contact mechanism and the contact mechanism electromagnetic contactor

The present invention provides an electromagnetic contactor contact mechanism and the contact mechanism used, the contact mechanism is configured to supply current can be suppressed when the movable contact opens and the electromagnetic repulsive force without increasing the size of the entire structure, and is configured to improved arc extinguishing property. The fixed contact member having a pair of fixed contacts (2a, 2b) inserted into the current path of (2) and with the said fixed contacts (2a, 2b) contacting and separating a movable contact portion (3b having , 3c) of the movable contact (form 3) at least one of a shape designed to generate the Lorentz force, the Lorentz force in the resistance when a current through the fixed and the movable contact portion between the contact portion, open along the electromagnetic repulsion pole direction generated. Arc suppression will be between a pair of fixed contacts and a movable contact portion produced towards the opposite side of the contact portion of the fixed driving force of the magnet (14a, 14b) provided in the fixed contact or the movable contact at least one.
