ABSTRACT:
An electromagnetic switch for a starter motor is disclosed in which powder produced by friction from repeated opening and closing of the stationary and movable contacts is prevented from entering in between the sliding parts of the movable iron core assembly, thus ensuring the smooth sliding motion of the movable iron core assembly at all times, and in which the penetration of external water into the space defined by the stationary and movable iron cores and the shaft member is effectively prevented thereby to avoid various troubles resulting therefrom.
