摘要： A solenoid for a vehicle starter includes at least one coil with a passage extending through the coil. A plunger is slideably positioned within the passage and configured to move in an axial direction between a first position and a second position. The plunger includes a substantially cylindrical outer surface portion with a circumferential notch formed in the outer surface portion. The at least one coil may include a pull-in coil and a hold-in coil wound on a spool. A plate member is positioned at one end of the spool and is separated from the plunger by a radial distance. The radial distance varies when the plunger moves in the axial direction as a result of the notch moving in relation to the plate member. A sleeve member may be coupled to the plunger such that the sleeve member covers the circumferential notch formed in the plunger.
