Abstract

PURPOSE: To prevent a contact or excessive access between electrode and starting auxiliary coil, by making the main electrode shaped into a flat pattern likely in a manner with its facing side to the starting auxiliary coil becoming almost flat face.
CONSTITUTION: A main electrode 20 is constructed with its electrode head part 22 shaped into a flat pattern likely as oval, ellipse, stream-line shape, etc. An electrode axis 21 is provided in parallel to a center line O1-O1 and eccentrically to one side from the center line O1-O1. The main electrode 20, made in such manner, is mounted with an almost flat face of the flat patterned electrode head part 22 likely facing to the starting auxiliary coil. The main electrode 20 and the auxiliary coil become isolated, thus no contact will be made between the main electrode 20 and the auxiliary coil.
