Abstract
Abstract Electrical components of an electronic switching device, such as a motion sensor of a monitoring system, are mounted on a dielectric carrier film covering opposite surfaces of a flat non-conductive support. The several components, disposed on the outer surfaces of the carrier film, are electrically interconnected by leads in the form of conductor strips on the inner film surfaces. A coil constituting such a component is embedded in a ferrite pot which is pasted onto an extension of the film and has a central pin with an end insertable into an aperture in an edge of the flat support after that extension is bent around the edge. The surfaces of the support may be pitted to provide recesses for an adhesive designed to bond that support to the film.
