switching between 12V DC and 240V AC

[Simon Allerton]

I am installing a fridge with both 12V DC and 240V AC supplies, which can’t be operated at the same time.
I could have simple off/on switches for each supply, but this risks accidentally having both on at the same time.

I would like to have a single switch that would switch from (12V on / 240V off), (both off), (12V off /240 V on).

Do such switches exist? most rocker switches I have found are either 240V AC or 12V DC, but not both together.

Any thoughts on how to solve this?

Thanks
Simon

Hi

This seems like a good idea on the switch.
Most switches will handle the 12 and 240 volts.

Here’s an example, you can see its rated for 12v and 240v

Just find the best switch the meets your needs with both ratings.
