Abstract
A switching device for switching a current between a first connection and a second connection including a series circuit of at least two JFETs (J-Jn), with further JFETs (J-Jn), which are connected in series to a lowest JFET (J), and wherein a wiring network for stabilizing the gate voltages of the JFETs (J-Jn) is connected between the second connection and the first termination. One additional circuit is connected between each gate connection (GJ, GJ. . . GjN) of the further JFETs (J-Jn) and associated cathode connections of diodes (DAV) of the wiring network. During switch-on and in the switched-on state, said additional circuit keeps the potential of the respective gate connection higher than the potential of the associated source connection.
