Question Battery switch behind the sofa

In our trailer, (92 Excella 29) there is a switch behind the sofa which seems to turn the battery power on or off. When we got the trailer, it was "off". The dealer had plugged up to shore power to show us everything was working properly.

We thought that switch meant the battery power (12 volt) was "off" and disconnected from the electrical system. However, imagine our surprise when, after we drove the 75 miles home, the monitor lights about the stove were working and then we found the ceiling lights all worked (dimmer than when we were plugged to shore power, but worked).

We couldn't figure out why the trailer seemed to have (weak) 12 volt power even though the switch behind the sofa in the front of the trailer was turned "off."

I read a thread about this switch and turning off the batteries, but it was mostly concerning much older or much newer rigs, and I got confused.
Can someone explain whether our switch is malfunctioning since we still have 12-volt power when it is off?

Thanks again. If you've answered this a jillion times already, I couldn't find it or wasn't sure it was the same question, so sorry.

I meant to say "monitor lights above the stove". I need to proofread before hitting the button, eh.

if you were still connected to the truck the power was coming from the truck. my switch disconnects everything but the break away switch.

Yup... Rich is most likely right.. Your tow vehicle was sending the 12volts back through the vehicle plug to supply power... This was probably all happening through a very small 14 guage wire so everything would be dimmer than normal.

I think there are two different types of switched discussed here. One looks like an ordinary light switch, and it is used to turn the converter on and off, usually to quiet the hum so the soul sleeping on the couch can sleep.

The other is referred to as the 12-volt disconnect, even thought that is not exactly right. Its function is to cut off the batteries so they don't drain during storage. However it is important to turn this switch to the "on" position when towing so the brakes will function if the trailer separates from the two vehicle and the brake pin is pulled.

some trailers have the 110 switch to cut the converter off, some do not. The 12 volt switch is a rotary switch in a little well in front of the sofa. with the converter switch off the 12 volt system will work if it is charged or hooked to the TV. on our first trip in the airstream we accidently and unknowling cut off the converter. and the batteries were old and the wrong kind. we had an interesting couple of hours trying to figure out where the electricity had gone.

I should have added. The umbilical was unplugged and the knob behind the sofa was turned to "off." And, yes it's the rotary switch that was turned "off."

The disconnect switch behind the couch removes 12 volt power from the batteries to the 12 volt circuit breaker panel. Anything else that is wired directly to the batteries like the LP Detector are still being powered. You can add a battery disconnect between the batteries and that will kill any 12 volt power.
