An electric gas-switch includes a switching chamber that is divided by a partition into an arc chamber and an additional chamber with a central pin being located within the arc chamber. The pin is embraced at least partially by a stationary switch part which is surrounded by a coil through which is flowing a cut-off current. One end of the coil is connected with an annular intermediate electrode which surrounds the central pin at a distance within the region of its free end. In an on position the central pin is embraced, at least at its free end, by the movable switch part that is designed in the form of a nozzle.
