Abstract
A glow discharge starter having an hermetically sealed, thin-walled envelope of vitreous material, a press seal located at one end thereof and containing an ionizable medium. A pair of non-segmented electrical conductors extend through the press seal and terminate in a spaced relationship to form a pair of electrodes within the envelope. The electrodes are held in the spaced relationship substantially by the press seal. At least one of the electrodes has a bimetallic element secured thereto. The bimetallic element is deformable by heat into engagement with the other electrode. Preferably, the envelope has a wall thickness in the range of from about 0.015 inch to less than about 0.025 inch.
