<P>PROBLEM TO BE SOLVED: To provide a contact mechanism and an electromagnetic contactor using the same which can suppress electromagnetic repulsion that breaks the contact of a movable contactor at the time of energization without upsizing the whole structure, and which allow the improvement of arc-extinguishing performance. <P>SOLUTION: At least one of a stationary contactor 2 having a pair of stationary contact parts 2a and 2b inserted in a current path, and a movable contactor 3 having a pair of movable contact parts 3b and 3c which can make and break contact with the pair of stationary contact parts 2a and 2b has a shape which enables the generation of Lorentz force to resist electromagnetic repulsion developed between the stationary contact parts and the movable contact parts in a contact-breaking direction at the time of energization, and at least one of the stationary contactor and the movable contactor has magnetic bodies 14a and 14b disposed thereon for suppressing forces which drives arcs generated between the pair of stationary contact parts and the pair of movable contact parts towards the respective sides of opposite stationary contact parts. <P>COPYRIGHT: (C)2013,JPO&INPIT |
