Things are slow, so I thought a little humor might be warranted...

=I would like to be able to turn on/off the power to either of

=component(s) that you feel would be necessary to achieve this objective.
=The switching action of CP1/2 must be controllable through a digital
=signal.  CP1/2 must each be able to switch 15A @ 12/24 V to their loads.

When I got this far, a solution popped right into my head.  CP1 and CP2 are
standard 15A toggle switches, the digital control being a finger of your
choice.  Simple, cheap, reliable.
