Abstract
Abstract This invention relates to a glow discharge starter having an hermetically sealed envelope containing an ionizable medium, a bimetallic electrode and a counter electrode located within the envelope. A silver plating completely covers the nickel-containing portions of the electrodes. Preferably, the thickness of the silver plating is from about 0.0002 inch to about 0.0004 inch. The present invention results in a glow discharge starter which has stable electrical characteristics, does not require the use of complex gas mixtures, and has an increased life.
