ONLY the hot needs to be switched.
The ground and common stay connected all the time.

You NEED a multi-meter to be SURE what terminal switches to what though.

Will that REALLY be easier than unplugging one and plugging in the other ??

And why two chargers ? A two or 3 stage charger is fairly easy to find these days that has a high initial rate and then automatically drops to a true float when the battery is full.

Sounds like OP is trying to make a transfer switch.
The common switch points, normally the center, would go to the load. One end set would go to genset, the other would go to the shore power connection.
You can use L2 for the neutral connections.
The grounds would be spliced straight through.
Is your TH a 30 or 50 amp? If it is a fifty amp, this will not work. You would need a three pole or a standard 50 amp RV transfer switch.
What is make and model of switch?

120V. I'm wiring up two battery chargers, switching from one charger to the other with one switch. Dino

What are you trying to switch? I assume it's 120v, and you probably just need a simple switch, not a DPDT from your question. Could you provide a little more info?
