ABSTRACT:
A gas-discharge switch for a low-pressure gas discharge contains at least two main electrodes. A distance d between the main electrodes and the pressure p of a working gas are selected so as to allow the igniting voltage to diminish with a rising product p.times.d. A hollow electrode, which is connected to a trigger voltage source, is allocated to the discharge gap. This hollow electrode is connected via an an anode resistor to the anode. Preferably, the hollow electrode can be additionally connected via a resistor to the cathode. With this refinement of the firing device, one achieves a pre-ionization inside the hollow electrode and a corresponding simplification of the firing device.
