BUT I ambiguity 9V battery build in what about?
excuse me! My english isn't good enough
Pin 6 on the LM386 should go to +9v (battery +)
pins 3 and 4 should go to earth/0v (battery -)
so there would be a short in that pcb (with the switch on).

thank you,I goto chance.hope IT OK.
S2 closed circuit,equality 9V + - connexity(short circuit)?
