The Use / Store switch is not DPDT switch. It is a temporary switch that enables or disables a latching relay.
In the Store mode, the house batteries are disconnected from the coach. When in the Use mode, the house batteries are connected to the coach to power your 12 appliances and accessories and to allow the Converter / Charger to charge the house batteries when plugged into shore power.
Some have a red light built into the switch. When the red light is on (when not on shore power), it lets you know you are in the Use mode. However, if on Shore Power, the red light can be on even when in Store mode.
