hi ray
each diode you add on phils rotary switch would give you a voltage drop of 0.6 of a volt
if you are in England/ uk try maplins for your bits
you need a
1 pole 12 way rotary switch order code FF73Q
and
diodes try 1N4002 1 amp 50v (don't worry about the voltage that's what it could handle) sorry have no code for these but maplins should be able to supply them or similar
hope this helps
