Why? no need, you just unplug one and plug in another gas
Far too much chance of injecting the wrong gas with multiple buttons
Just like on OC stages, Find the tank, check its the right one, Get buddy to check its the right one, plug it in, squirt, should be no gas. Turn on correct tank and squirt should be gas, Turn off old cylinder and stow whip. Easy, no extra kit (other than cheap Buddy whip on stages)
Multiople injectors add more failure points and add more chance of you injecting the wrong gas. Dont do it. Heck I know folks that blank off the Diluent inject once they have an ADV to remove a possible point of failure. They plug everything in on the O2 side is they need to
Or you could get Bob Howells fixtures and fittings (see his site)
