The disconnect switch works just like any other electrical switch. It''s located between the battery''s negative terminal and the power-supplying cable. Flipping the switch to the "on" position cuts off the power from the batteries to all 12-volt appliances in your RV. This prevents your RV batteries from being drained when not in use.
