An engine starter includes a starter switch having a plunger assembly movable between non-operating operating positions. When the plunger assembly is at the non-operating position, a gap between main stationary and movable contacts is smaller than the sum of a gap between a pinion and an engine ring gear and the most-widely opened variable gap, which is defined between a drive mechanism and a moving shaft. The arrangement is such that, as the plunger assembly moves from the non-operating position to the operating position, the auxiliary contact is first closed to cause the starter motor to be driven at the first speed, and then the main contact is closed to cause the starter motor to be driven at the second speed.
