The pressure switch is designed to control an outlet (or send a signal to a controller if you get that version) and therefore would need a pump in a reservoir of RODI to do what you're talking about.
I don't think it can control a RODI unit directly unless maybe you hooked up a pressure switch/valve that you could connect to your controller. Since you asked about apex or rk, I'm guessing you don't have either yet and are trying to figure out which one will work?
Please give us some more info on your specific equipment and your actual intentions.
The auto shut off valve that comes with most rodi systems operate with pressure not electronically. These auto shut off valves are meant to work with a float valve that when closed creates back pressure on the system which in turn causes the auto shut off valve to "shut off" the waste water and the incoming water. What you can do is install the float valve in your sump.
I use the same container that Ryan linked. I notched out the lock on the lid thought instead, and made an opening for my ATO pump power cord and tubing.
I fill mine manually a couple times a week so being able to open and seal close the lid easily was why I did it that way.
