If the ignition switch is turned to the "START" position,
current  flows  in  the  coil  provided  inside  magnetic
switch,  attracting  the  plunger.  When  the  plunger  is
attracted,  the  lever  connected  to  the  plunger  is
actuated to engage the starter clutch.
On the other hand, attracting the plunger will turn on
the magnetic switch, allowing the "B" terminal and "M"
terminal to conduct. Thus, current flows to engage the
starter motor.

When the ignition switch is returned to the "ON"
position after starting the engine, the starter clutch is
disengaged from the ring gear.
An overrunning clutch is provided between the pinion
and the armature shaft, to prevent damage to the
starter.
