Here is the link to the Amtrol switch.

If you look at the 2nd page of the pdf file, you will notice the wiring hook up is exactly as same as on typical mechanical switch.
I heard this kind of digital control/switch is a fairly new for well pump usage and Amtrol is the only brand for now. That's hard for me to believe it in time and age... but then I am a newbie in this field.
