It doesn't switch between tanks. whatever tank you have open and are using you have it on green. When it runs out you flip the knob so that the empty tank is red and the new tank is green. its entirely pointless if you have both tanks turned on. It's just a visual. I wish it was smart enough to regulate and switch between tanks, etc. Its not.
That looks to be a Mr. Heater brand auto valve, and it will switch its input from empty tank to full tank automatically if it is working properly.
Assuming you start with both tanks full and both valves open, the regulator will draw from the tank to which the valve handle points until that tank is empty. Then it will switch to the remaining tank and the indicator will change from green to red indicating that the first tank is empty. At that time you switch the valve handle toward the full tank, and fill the empty one.
