12 Volt Switch

Assuming you have a converter feeding a 12VDC FUSE PANEL...

This is typical wiring block diagram for the 30AMP system...


I would work towards using a converter/charger and install a Power Distribution Panel which supports all of your 120VAC circuit breakers and 12VDC Fuse panel...

Typically the 12VDC power distribution panel id fed by both the converter/charger and the battery. This is the way things like your ceiling lights can work when you are plugged into shore power or running off your battery.

This is what a typical POWER DISTRIBUTION PANEL with the Converter/Charger installed in the bottom compartment looks like


If your trailer does not have one of these it would be good idea to get one installed where you can have all of your power items in one location separately feeding all of your 120VAC and 12VDC circuits.

Who knows what the fire dept did to your trailer...

Donn.....battery is on a frame and fuse box in rear of camper. Where would convertor be?

Never heard of any switch? Unless you mean a battery disconnect switch. This will be a fairly large switch, usually red in color located between the converter and battery. Lights should all be 12 volt, so if when unplugged you have no 12VDC, then you either have a dead battery, or blown fuse
