When
Start Button
is
Pushed:
When the start button
is
pushed on, a current flows from the battery through the pull-in coil
in
the
magnet switch section to the
holding coil, energizing the plunger
to
pull it in.
At
this time, the
pinion moves
by
the drive lever
to
engage with the ring
gear.

When contact
plate
is
closed:
When the contact plate
is
closed, a large current flows through the motor section
to
generate a
large mechanical power which turns the engine crankshaft.
At
this time, the pinion
is
moved forward
by
the screw spline for more contact.
Since the pull-in coil ends are short-circuited
by
the contact
plate,
the plunger
is
held only
by
the
force of the
holding coil.
