Abstract

An electrical switching device includes a hermetically sealed housing enclosing at least one power switching component mounted on a cooling plate and a plurality of connector parts which are guided out of the housing. In order to eliminate heat generated by the switching component, portions of the connector parts within the housing are embedded in a heat conducting, electrically insulating material which is in contact with the cooling plate such that the heat is abducted via the cooling plate, the heat conducting material and the connector parts by a heat conducting and electrically insulating foil.
