Abstract (en)

[origin: EP0433480A1] The hollow electrode switch contains at least two electrodes which form a discharge path for a low-pressure gas discharge, and to which a hollow electrode is allocated. According to the invention, means for generating a spatial charge, especially a glow discharge, are provided inside the hollow electrode (10). This hollow electrode (10) is provided as the anode for the spatial charge and is electrically insulated from the electrodes. In consequence, a particularly simple embodiment of the hollow electrode switch is obtained, with a short switching delay time and small scatter. …<IMAGE>…
