Abstract
A gas-discharge switch contains at least two main electrodes for a low-pressure gas discharge. 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. According to the present invention, a hollow electrode, which is connected to a trigger voltage source, is allocated to the discharge gap. The main electrode facing the hollow electrode is provided with a central opening. Between this opening and the hollow electrode, a baffle plate for the ion current flow of the low-pressure gas discharge is configured with a pre-set clearance from the surface of the main electrode.
