Battery switch

Blue Sea
6006200, M Series Mini Battery Switch, Black, Single Circuit ON/OFF w/ Knob
I'm new to my RV and trying to figure out what everything does and why different things aren't working. Can anyone tell me the purpose of this switch?

I can also include my landing gear on the list.

Majority of Battery Disconnect Switches do NOT disconnect all loads.....
Parasitic loads can be LP/CO Detectors, Radio, Clocks etc

Many folks turn it off expecting ALL DC is shutdown only to return weeks later and find batteries DEAD

Really depends on HOW the disconnect switch has been installed.
Don't 'ASSUME' it shuts down ALL DC

Look at the Battery POS Post....does it have just one large cable connected to it or does it also have several smaller gauge wires connected.
Smaller gauge wires probably do not go thru disconnect switch

That must be RV specific because in my 2017 Coachmen, the battery disconnect definitely disconnects everything, including the CO/LP detector (the green light goes out when I turn off the disconnect).

I'm surprised that's not universal behavior since it wouldn't be a very good disconnect if it doesn't actually disconnect everything.

Newmar was or still is a OEM that does NOT disconnect the Co and LP detector. Newmar stated that you could still be using the RV with the Disconnect turned OFF and you needed the CO and LP still operational at all times. Doug

That switch is supposed to shut off all those electronic systems when you turn it off.

Mine, a Coleman, disconnected everything and when I do that, it stops the battery from draining and was able to be topped off by. a small solar battery charger-maintainer.

That is a Manual ON/ OFF SINGLE battery switch. Not designed for more than one battery. It is usually installed to turn OFF all of the connected Battery loads(appliances/Circuits). But, depending on who installed it and the parameters from who installed it, it may NOT shut off all Battery loads. But, you need to leave the Disconnect ON at all times when using the RV. When stored with no 120 volts connected turn it off. THEN go inside and see if you find any 12 volt item still on. Some that may bypass the disconnect. Doug
1. CO detector
2. LP detector
3. TV antenna booster(very rare but does happen)

It is used to cut off power from the battery to 12V systems in the RV. This can be done for maintenance when you do not want to work on an energized system or when the RV is in storage. If the RV has multiple banks of batteries then a similar switch can select which bank or both banks are in service.

Don't worry about asking questions we were all new at this at one time.
