Superb suggestion Terry!!! I never knew this existed. Here is the link to my
schematic:

It was drawn quickly with a simple drawing program so apologies if it looks
a bit amateur. I used to have schematic capture, SPICE, and other PCB layout
software running but not on this machine.

I still don't follow what you are using for switches. I would expect
someone to use single pole switches. Single pole switches don't have
any unused outputs.

What type switches are you suggesting?

I use a program called TinyCad. It is free and pretty easy to use.
