The hermetically sealed electrical feed-through device has a circular metal disk (11, 21) with a conductive isolated pin (13, 23) hermetically sealed in a through-going circular opening (O, O') by a glass seal (17, 27) and a conductive ground pin (15, 25) connected with a rear side of the metal disk (11, 21) adjacent to the through-going circular opening and extending approximately parallel to the isolated pin. The isolated pin (13, 23) has an oval or elliptical section (13a, 23a) extending through the glass seal (17, 27), whereby different bridge wires of different lengths are connectable on the front side of the metal disk between the front surface of the metal disk and the isolated pin (13, 23). In one embodiment the pins are straight and the through-going circular opening is offset in the metal disk; in another embodiment the pins are bent and the through-going circular opening (O,O') is centrally positioned in the metal disk (11,21).
