Abstract

PURPOSE:To certainly prevent burning of a stabilizer due to fusion of thermo-element by fitting the material having low melting point at the discharge part or in the vicinity of the discharge part. CONSTITUTION:In normal state, the auxiliary discharge between a main electrode 3a and an auxiliary electrode 10 allows a bimetal 6a to operate, and the translation to the main discharge between the main electrodes 3a and 3b is performed. The contact between the movable contract 15 of the bimetal 6b and a fixed contact rod 14 is released after the translation to main discharge. If the movable conact 15' of the bimetal 6a and a contact lead 21 are fused, the bimetal 6b operates, and discharge is generated between the parts having different potentials. As a nickel sleeve 23 as the material having low melting point is installed at the both ends of a filament 7, the nickel sleeve 23 is fused by the heat generated at both ends in discharge, and the feeding of current to the main electrode 3a is brought to stop, and burning of a stabilizer can be prevented.
