Few questions about Spider Controller (DAGU)

Hello all!

I'm newbie and I have few questions about Spider Controller (from DAGU).

1) When USB is plugged and the battery is plugged too - which source of power controller will be use for servos?

2) As i understand, If i use analog servos I should plug it to PWM-outputs. And digitall servo can be plugged to any output. Am i right?

3) Can't understand what is the role of ON/OFF switcher. It is for battery only?

 

Many thanks in advance.
