Abstract
A glow discharge starter having an integral thermal protector includes a glow bottle having an hermetically sealed discharge envelope containing an ionizable medium, a bimetallic electrode and a counter electrode. A pair of conductors extend from the main body of a radio frequency suppressing capacitor and electrically couple respective electrodes of the glow bottle. The cylindrically-shaped main body of the capacitor is coaxially positioned with respect to the discharge envelope so as to be responsive to heat generated within the envelope. When an abnormal temperature limit (e.g., 450 degrees Celsius) is reached by the discharge envelope, a short circuit is created within the main body of the capacitor and extinguishes the discharge.
