GLOW-DISCHARGE STARTER WITH TWO BIMETALLICS AND A REVERSIBLE HYDROGEN GETTER

摘要

PHN 9747 7 The invention relates to a glow-discharge starter having a bimetallic electrode and a rare gas. According to the invention the glow-discharge starter also comprises a reversible getter which, when the temperature increases, gives off a gas and, when the temperature decreases, absorbs the gas and the value of the gas pressure also determines the electric conductivity of the glow-discharge starter. In this way a glow-discharge starter is obtained in which undesired breakdown can be prevented by controlling the gettering temperature.
