Abstract

This invention relates to a glow discharge starter including a glow bottle having a hermetically sealed discharge envelope containing an ionizable medium, a bimetallic electrode and a counter electrode. A pair of conductors extending from the main body of a radio frequency suppressing capacitor electrically coupling respective electrodes of the glow bottle. The main body of the capacitor is in a thermal relationship with the discharge envelope and responsive to heat generated therewithin. When a predetermined temperature limit is reached within the discharge envelope, the generated heat creates a short circuit within the main body of the capacitor and extinguishes the glow discharge. The present invention eliminates the need for an additional fuse member or thermal protector.
