Square D brand like traditional AC pump pressure switches, just working in reverse electrically. These switches complete a circuit with 2 signal wires when the pressure is up to the setting. Those 2 signal wires run into and any RPS Solar Pump Controller (RPS 200, 400, 800 Pumps and RPS Pro Series) Set to 30/50 psi by default but adjustable. Remember each psi means 2.31ft of head on your pump. 

Since AC pump traditionally are powered on and off with a pressure switch located on a tank tee of a pressure tank, many times there are not signal wires setup underground between the well head and the storage tank. Not a problem. An alternative to wires is a pressure switch attached to the plumbing from the well head to the tank. At the pump you’ll need a check valve, and on the tank you’ll need a mechanical float valve (ball float that closes a 3/4″ or 1″ valve and shuts off water) that will spike pressure in the line when it closes. Somewhere along the line between the two you need a ‘Tee’ with 1/4" Male threaded nipple and a reverse action pressure switch to your pump controller.

Let us know if you have questions but they are really easy to install and wire!
