    摘要： A contact mechanism includes a fixed contact and a movable contact adapted to be inserted in a conducting path. The fixed contact includes a pair of flat plate conductive bodies disposed and fixed to maintain a predetermined interval. The movable contact includes a flat plate conductive body disposed to face the pair of flat plate conductive bodies of the fixed contact and capable of contacting with and separating from the pair of flat plate conductive bodies. Current paths wherein each of the current paths has a current flowing in a same direction are formed at least two side portions of the flat plate conductive bodies of the fixed contact and movable contact mutually facing each other in a width direction.
