I have an evercool portable fridge in my utility for camping, I also use it at home,  12volt battery when I camp and 240volt to 12volt adapter at home, I want to wire up a switching set-up to change over from one supply to the other, l thought of doing this with two relays controled with a centre off switch, I am wondering if anyone can help me to use mosfets for the switching, at present I am just swapping plugs over, would like something better
