Abstract
PURPOSE: To prevent blacking of the outer bulb due to spattering by covering the contact of bimetal switch with a cover.
CONSTITUTION: A starting voltage generator consisting of a resistance and a bimetel switch is contained in the outer bulb, the cover 20 for the contacts 17, 19 of the bimetal switch 13 and the shield 22 which forms a shade crossing the switch base are provided. When the switch 13 is opened, the contacts 17, 19 produce spatter. The spatter is checked by the cover 20 and is not attached to the inside of ourter bulb, blacking can be prevented. Also the shield 22 forms a shade between the bimetal 16 and the contact element 18 on the base 15 to attach no spatter to the base, a closing due to a short between the bimetal and the contact element can be prevented.
