Iggy's solution is far safer than the silly panels with switches linked
together. Specifically, it is fail safe.

It's only safe as long as someone follows the rules and there is
only one key. You could just as easily leave out the key and just
keep the rule, "Thou shalt switch OFF the one before you switch ON
the other", which is nothing at all like a proper transfer switch.

I will put the second key in the bank safe deposit box. Or even throw
it away.
