How To Wire A RV Rotary Cam Selector Changeover Switch

[MtSparky]

I build teardrop trailers as a hobby. In my electrical box where I supplied power to the trailer interior, I have a lithium iron battery, a 120V Power Converter /Charger, and a 12v to 120v Inverter to power 120 outlets. I want to power the outlets from grid power without back-feed powering the inverter because it burned up my last inverter. So when I switch to #1 position I am powering the outlets from grid, and on #2 position I am powering outlets from the battery and Inverter. I need to keep the inverter safe How can I wire this switch to accomplish this?

That switch would be hard to wire as it switches different contacts with no common, you also need to make sure they are break before make switches,as well as suitable for the loads involved
