ABSTRACT:
An electromagnetic switch for a starter motor has a movable contact and a pair of fixed contact which are brought into contact with each other by the sliding movement of a plunger in an exciting coil; a B-terminal bolt formed integrally with one of the fixed contact, and a connecting terminal having an end surrounded by a surrounding insulation body and the other end functioning as a contacting seat portion which is fitted to the B-terminal bolt, said connecting terminal being extended in the radial direction and at a predetermined angle with respect to the insulating cap, wherein the outer configuration of the contacting seat portion of the connecting terminal is circular or a polygonal having an obtuse angle; the contacting seat of the surrounding insulation body is embedded in a resin-molded body except for its front and rear contacting surfaces; and the connecting seat portion has at its outer circumferential portion turn-prohibiting projections which are in contact with a side surface of a projection formed at the central portion of the outer surface of the insulating cap, whereby an angular position of the connecting terminal to be extended at a predetermined angle is determined with respect to the insulating cap.
