I'll reply, tomorrow or the day after, with a schematic which will
solve your problem.

That's very kind.

That's great - thank you sincerely. It appears fairly simple and I look
forward to trying to implement it.

This is my first time reading a schematic in ascii, and it mostly makes
sense to me. My only question is what does "O" represent? For example,
there is an "O" next to CP1. Thanks for your patience.

The 'O' is used to represent what's called a 'low true' input. That
is, a desired result occurs as a result of that input being at a
logical '0'. In this case, that's zero volts or 'ground'

The other "O"s (at the switch) are just a convention used to denote a
switch (or relay) terminal.
