Abstract

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.
