The present invention addresses the problem of providing a contact mechanism that has a long contact life span without an increase in electric resistance. To this end, the present invention provides a contact mechanism that comprises an opening/closing fixed contact (35a), an opening/closing movable contact (37a) that faces said opening/closing fixed contact (35a), and a permanent magnet that extends, in a prescribed direction, an arc generated between the fixed contact and the movable contact. In particular, an arc (A1) generated from contact surface regions (35d, 37b) at which the opening/closing fixed contact (35a) and the opening/closing movable contact (37a) make contact is extended by the magnetic force (B) of the permanent magnet, and the arc (A1) is moved to non-contact surface regions (35e, 37c) at which the opening/closing fixed contact (35a) and the opening/closing movable contact (37a) do not make contact. |
