Hi all

I'm trying to figure this out, I've seen a few products now where they 
place two fuse holders on the board, by putting the fuse into the 
appropriate one you set the mains voltage 230 or 115 volts.  However I 
can't figure this out, by transformer have two windings on the primary, 
with 240V you have to connect them in series and for 120 in parallel, 
how can this configuration be made using two fuse holders, one empty 
the other setting the primary configuration!?

Its been bugging me, but I'd like to do it that way if I could figure 
it out!

Cheers

Ed
