Something tells me that it may have been just a little simpler to use a 12V DPDT relay.
Unless the relay was latching, one would need to build a circuit to accomplish the latch and hold. Also, the relay would need to remain energized in one position if it were not mechanically latching, meaning if power to the relay was lost it would revert to the spring state.
You may have a junque box full of them, but latching relays with a 12 VDC coil and contacts rated for a minimum of 20 amps inductive are sort of scarce around here.
Being a Ham, you should understand the true meaning of the term "Homebrew" and repurposing. You don't always do the simplest thing, you do the one that you can accomplish with what you have on hand. BTW, I have some 807's and 5U4's I'm tying to figure out how to use in the RV. So far, the only thing I can think of is a neat table lamp base. Of course, it would be easier to just go out and buy a new table lamp. :W
