を特徴とする回路しや断器の接触子機構。 A cross bar is provided with a contact holding part that holds the movable contact of each pole and is rotatably supported in the housing, and has a movable contact in the front part, which intersects with the axial direction of the cross bar. a movable contact which is pivotally supported by the contact holding part by movably and rotatably inserting a shaft pin fitted into the intermediate side surface into a holding groove formed in the contact holding part so as to be oriented in the direction of the contact holding part; The receiving pin that can be inserted into the rear side of the movable contact and the spring receiving protrusion provided on the contact holding part are compressed with their ends abutting each other, and the receiving pin is biased toward the front of the movable contact. In the contactor mechanism of a wiring sheath cutter, which consists of a coil spring that applies contact pressure to a movable contact, the positional deviation between one end of the wire that makes up the coil spring and the other end is measured perpendicular to the axial direction of the coil spring. A contact mechanism for a circuit or breaker, characterized in that the central angle of the cross section is approximately 45 degrees to 90 degrees.
