Switching between dc and ac power for refrigerator

[rnelson1020]

I have a 2022 Aliner Ranger 12 with a portable, slide-out refrigerator that will operate on 12v dc or 110v ac. However, the power cord has to be changed to go from one power source to the other. This is a bit of a pain. I would like to install a switch that will allow me to run a connection from the ac outlet and the dc outlet to the input side of the switch and the outout side continuing to the fridge, which would allow me to choose the power source for the fridge. Both power sources plug into the same power connector on the fridge. This setup will remove the need to change out the power cords when going from dc to ac. Any ideas would be greatly appreciated.

The cord connects to different pins on the plug (THe part on the fridge is technically a plug not a socket) when you plug it on. So nto easy

Suggestion Run it on ``12 volt and let the converter make 12 volts.

It's 2 cords with plugs and one socket. A switch is a given, the trick is to come up with how to combine the pin positions or keying of the two different plugs.

Cut the plugs and socket from the existing cords and wire them into the above switch.

Won't work. If there are 4 sockets on the cord ends only two on each will be active.

More likely one of the cords has a transformer in it and converts the 120vac to 12vdc. The fridge end of the two cords would be identical 12v sockets. The primary difference between the two cords is one has the transformer and one does not, and the plug that goes to the power source differs as well.

If that's the case,

That switch will not work
The frige's "plug"(the part on the cord is a socket, Onto which the cord plugs has at least 3 pins.. Now you are used to "Hot, Neutral, Safety ground but that's not what they are.
120.. Common 12 volt are their ID's.
