What Switch or Component Will Work?

It might do it, so I've put a drawing "Combi-switch.png" on the A.B.S.E group

Use three toggle or slide switches, one across each existing switches. Turn a switch on to disable the one(s) you don't want to use.

What if the circuit is AC? How about snubbers to protect your diodes?

use a 2 pole rotary switch to give you the combinations, and use diodes for the selection of any 2 switches or any one.. or all in series. basically, just tie them all in series.. and use diodes to select the pairs. THe diode will prevent back feed to other combinations. The circuit will have to be DC.

Any more home work questions?

parrallel each switch with a normal switch. turning that switch takes it's parnmer out of the equation,

Thank you for getting back to me so soon. You asked if I have anymore home work question, well you've got it.

I can work off a schematic very easily. Once I've built a circuit and understand how the components work together, I can then make up my own circuits involving those components. Each time I put together a circuit I document it and use it as reference to build a new circuit. I know this is real basic but if I had a schematic it would get me going and I would never have to ask you anymore questions about this type of circuit, I think? So if you really want some more home work I would surely appreciate it if you could come up with a schematic using your recommendation on how I should be done.

Thanks Again for Your Help
