    摘要: A switching contact arrangement is for a power switch, wherein a plurality of contact levers are pivoted on a contact support via a bearing pin. The contact support is provided with at least three support elements for radially supporting the bearing pin. In order to simplify production of the contact support, at least three of the support elements are configured as a one-piece shaped element that forms the contact support. At least one of the support elements can have a metal element that is at least partially embedded in a plastic shaped element of the contact support. The metal element can be configured as a sheet metal part.

    摘要: An arrangement for controlling the movement of a drawout circuit-breaker, mounted in a switchgear, which can be moved in an operating position, test position and disconnect position relative to a drawout frame using an actuating shaft pivoted in the drawout frame and operated by a detachable actuating crank. A controllable closure member enables or prevents the actuating crank from coming into contact with the actuating shaft, and the drawout circuit-breaker can be removed from the drawout frame after a door is opened. Such arrangement is used in low-voltage circuit-breaker equipment.
