Since all you're doing is switching +12 to one appliance or the other, you
just need an SPDT switch. If you want to have a middle "off" position,
where neither appliance receives powers, then you're looking for an SPDT
switch called an ON-OFF-ON one. The more common two-position SPDT switch
is called ON-ON.

Do I need a single pole double throw switch, or a double pole, double throw switch? I'm guessing the latter, but wanted to doublecheck. The SPDT would operate two appliances at the same time then presumably vs a SPST? Just a bit confused here on how these work.
