As Chris previously mentioned, the Intellitec Monoplexer is the easy way to accomplish what you want to do.

I'll second this recommendation. Looks like the 10 amp version can be had for 50 bucks. I didn't see a price for the 15 amp version. You can do the job with a generic latching relay, maybe for less money. This device is just an electronic latching relay. My rig has one, with 3 switches, and so far it has worked flawlessly.
