• When releasing key switch
When releasing the key switch (6). it returns from "START"
to "ON" position and the starter circuit opens. Then, current
flows from the battery (9) to the pull·in coil (8) and the
holding coil (5) through the contact plate (7). Since the
magnetic force is generated in each coil in the opposite
direction, the magnetic field collapses and the plunger (4) is
returned to its former position by a return spring (3). This
opens the contacts on the contact plate (7) and separates
pinion gear (1) from ring gear (2), whereupon the pinion gear
stops rotating.
