Great questions. The spring terminals would allow you to connect input devices other than the included momentary buttons. The most common is probably a float sensor. So, for example, you can install a float switch in your skimmer collection cup that will switch from open to closed when the cup is full and you can program the Apex to turn off the skimmer when the switch is closed with a single line of programming in the skimmer outlet as follows: "If Sw6 Closed then OFF." Of course you'd have to swap out "Sw6" for whatever name your Apex gives that terminal.
You could just as easily install a pressure button in your cabinet or a magnetic two-piece switch so that, when you open your cabinet a light goes on.
As for where they show up, as soon as you plug in a new break out box or one of these hybrid boxes, Apex will recognize it and place the new tiles in Fusion. You just need to drag them to where you want them and sometimes need a title trial and error to figure out which is which. If you follow my build instructions they will number sequentially in the order I mapped out above but depending on your configuration it may not start with Sw1.
As for the programming, that's beyond the scope of this thread and each use would be different. There are dozens of threads here on R2R that provide the code. One that I created for the automatic water change is: https://www.reef2reef.com/threads/apex-programming-for-on-demand-water-change.293593/#post-3683473. If you search for your particular goal, chances are you'll find the answer. There are also great examples in the Neptune comprehensive user manual. If neither source gives you the answer, post a thread and the group here can help you design the code.
Good luck.
