PURPOSE:To prevent burning of a stabilizer certainly and easily by forming at least one of the parts having different potentials into easy-to-discharge shape. CONSTITUTION:In normal state, the auxiliary discharge generated between a main electrode 3a and an anxiliary electrode 10 allows a bimetal 6a to operate, and the translation to the main discharge between main electrodes 3a and 3b is performed. The contact between the movable contact 15 of the bimetal 6b and the fixed contact rod 14 is released after translation to main discharge. If the movable contact 15' of the bimetal 6a and a connecting lead 21 are fused, the bimetal 6b operates, and discharge is gnerated between the parts having different potentials, and a protruded lead 23, contact lead 21, filament 7, bimetal 6b, or filament fixing rod 22 or 5a is fused, and then current stops, and burning of a stabilizer can be prevented. |
