I did not mean to sound demanding, being my first post and all. Thanks for your picture. It appears they are no convenient way to do this with one switch and also not take up much space.
THANKS

OK.
I have 4 - 12 volt batteries.
In parallel is 48 volts and series is 12 volts.
I would like have a series/parallel switch for running in 12 volts or 48 volts.
Most important, I would like to have a diagram for just how to wire this up.
