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.
