Battery cutoff switch

Thanks for the replies!

Normally......yes.

Yes!!

My guess is the yes it will disconnect the charger so the battery will not charge if you are plugged in with the switch off.

The cut-off battery switches usually cuts-off anything down-stream from the battery terminals except those 12VDC connections that are directly connected to the battery terminals... My 5th Wheel battery terminals has the TRAILER TRAILER EMERGENCY DISCONNECT Box which includes the 12VDC jumper going to the truck 7-way connection, the Trailer Slide-outs, and the Trailer Front Jacks all remaining direct connected to battery terminals.

The BATTERY DISCONNECT SWITCH opens the circuit between the Battery Terminals and the 12VDC Power Distribution Panel which is co-located with the Converter/Charger unit panel.

My Trailer Converter/charger unit connects to the same point on the 12VDC Distribution panel. This means when I am connected to SHORE POWER all of my 12VDC items running from the 12VDC Distribution Panel will have 12VDC being generated by the Converter/Charger unit. When my BATTERY DISCONNECT switch is engaged (OPENED) I will not be able to re-charge my batteries when plugged into the SHORE POWER Connection.

I installed my own BATTERY DISCONNECT SWITCH in my Fifth Wheel Trailer which is wired for two 12VDC batteries and My OFF-ROAD POPUP trailer which is wired for 4ea 12VDC batteries. I used the BLUE SEA 4-position HD Battery rotary switches that selects batteries from my two battery banks (OFF-BAT1-BOTH-BAT2)...

This is how my two trailers Batteries are hooked up - Not sure if all the rest are connected this way or not...

Mine won't charge either when battery cut-off switch is activated. Haven't used it much as I have my rig plugged in 24/7 when not RVing.

Mine will keep it from charging when open/off. It is in line between the convertor and the battery, located next to the convertor but is separate.
