Reduction Starter.

Operation

<3> Return
When the ignition switch returns from the START position to the ON position, current flows from the magnetic switch main contact side to the hold-in coil via the pull-in coil. At this time, since the magnetic force set up by the pull-in coil and hold-in coil cancel each other out, there is no magnetic field to maintain the plunger position. Therefore, the plunger is pushed back by the return spring, and the main contacts are switched off, stopping the starter from revolving. The figure on the left below summarizes the flow of current in the return step.
