The invention relates to a contact arrangement particularly intended for current limiting low-voltage circuit breakers, the contact arrangement having an elongated movable contact (10) which, at its mid-point, is rotatably journalled about a rotational axis (A) directed perpendicular to the longitudinal axis of the contact. The movable contact cooperates with two fixed contacts (20, 21) which are arranged on opposite sides of the movable contact. In the closed position of the switching device, the movable contact is pressed against the fixed contacts with the aid of a torsion spring (18) which extends parallel to the rotational axis of the movable contact and which, on one side of the movable contact, is in engagement with the movable contact and, on the opposite side, is in engagement with the stand of the switching device. |
