• Current flows from the battery through terminal "50" to the hold-in and pull-in coils. Then, from the pull-in coil, current flows through terminal "C" to the field coils and armature coils.
• Voltage drop across the pull-in coil limits the current to the motor, keeping its speed low.
• The magnetic switch plunger pushes the pinion gear to mesh with the ring gear.
• he screw and low motor speed help the gears mesh smoothly.
