• Motion of operation mechanisms

Figs. 24 - 27 illustrate the motion of the charging and ON-
OFF mechanisms.

Fig. 24 Closing motion 1 (discharge motion)

For  manual  closing  operation,  ON  button  (1)  rotates
counterclockwise.  For  electrical  closing  operation,  push
rod  (1)  protrudes  downward  from  the  latch  release  coil
(LRC) and charge latch trigger (2) rotates clockwise. This
rotates  closing  trigger  shaft  (3)  clockwise  and  closing
release  lever  (4)  disengages  from  a  semicircular  pawl
and  rotates  clockwise.  And  charging  cam  (5)  rotates
counterclockwise, so  that charging  lever  (7) disengages
from  closing  spring  (6)  and  rotates  counterclockwise.
Closing cam (8) is pushed up by charging lever (7) and
rotates  clockwise.  At  this  time,  each  component  is
positioned as shown in Fig. 26. Continued to Fig. 25.

Fig. 25 Closing motion 2

Closing  cam  (8)  rotating  clockwise  causes  closing  link
and top link (9) to be pushed straight. This rotates closing
toggle  cam  (10)  connected  with  closing  link  (9)
counterclockwise, so that crossbar (11) rotates clockwise
and  thus  moving  contact  (12)  comes  in  contact  with
stationary  contact  (13).  At  this  time,  each  component  is
positioned as shown in Fig. 27.
