The hermetically sealed electrical feed-through device has a circular metal disk (11) with a conductive angular or bent isolated pin (13) hermetically sealed in an oval or elliptical through-going opening (O) whose center coincides with the center of the circular metal disk. The angular or bent isolated pin (13) is sealed in the oval or elliptical opening (O) by means of a glass-to-metal seal (17). An angular or bent ground pin (15) is connected to the rear side of the circular metal disk (11) adjacent to the opening (O) and extends approximately parallel to the isolated pin (13). Because the through-going opening (O) has an elliptical or oval cross-section section, different bridge wires of different lengths are connectable on the front side of the metal disk (11) between the front surface of the circular metal disk (11) and the angular or bent isolated pin (13). The isolated and ground pins both have circular transverse cross-sections.
