That's a link to transfer power from your chassis battery to your house battery, or vice versa.
If your house batteries are down, start your engine and, while holding that button in, use the power from your chassis battery to start the generator. If your chassis battery is down and you can't start the engine, start the generator, hold the button, and start your engine from the house battery.
Strictly speaking, you don't have to start the engine or generator before using the transfer switch, but it's protection against drawing down the second battery as well.
