Abstract

A switching device has a substrate, a connection device and a pressure device, wherein the substrate has electrically insulated conductor tracks, and a power semiconductor component is on one of the conductor tracks with a first main surface and is conductively connected thereto. The connection device is a film composite with conductive film and an insulating film and forms a first and a second main surface. The switching device is connected by the connection device and a contact area of the second main surface of the power semiconductor component is connected to a first contact area of the first main surface of the connection device in a force-locking and electrically conductive manner with a pressure body and a pressure element projecting toward the power semiconductor component.
