Abstract

A solenoid for a vehicle starter includes at least one coil with a passage extending through the coil in an axial direction. The solenoid further includes a plunger configured to move in the axial direction within the passage. The plunger includes a cylindrical outer surface with a substantially uniform diameter and a circumferential notch. The cylindrical outer surface includes a first portion with a first diameter on one side of the circumferential notch, and a second portion with the first diameter on an opposite side of the circumferential notch. The circumferential notch includes a portion with a second diameter that is less than the first diameter.
