I am using a Franklin submersible pump that asks for 40# on and 60# off pressure. My well is approx. 100' from the pressure tank. I have all of the check valves ball valves and such.
the pressure will range from 60# to 0# and the pump seems to be turning on whenever it likes

You can go to the Square D web site http://www.squared.com/ to get the answer. They have a customer support section which has helped me in the past. They may need any data you can provide on the switch, like a model number and the voltage to your pump that the switch controls, so they can help. At least, they can tell you where to adjust the high and low setting, and how to wire it. Be careful, you can get a nasty shock or arc if you short anything while the power is on. As long as the power to the pump is wired through the contacts of the switch, the opening and closing of those contacts is what turns the pump off and on. 40# on and 60# off means the switch should be adjusted to turn the pump on at 40#, off at 60#. That gives it a 20# range which is where you have normal water pressure in your tank. I hope this helps.

Most Square D switches are factory set a t 20#'s on and 40#'s off. To adjust, screw down the tall adjustment screw in the middle of the switch. It will adjust the on and off settings and keep the 20# differential. Do not adjust the little adjusting rod at the back of the switch. If will just cause you grief!!! Usually the switch is wired for 220 volt pump motors. Two contacts will have marked "Line". The two wires from the power source go to those screws. The other two screw posts will have "Load" marked on them. The wires to the motor go there. Ground the system with a ground wire to the green screw at the bottom of the switch housing. You will then be ready to go!! Good luck!

All the Square D pump pressure switches I've installed have two ,(usually philips head), screws at each set of points. You should be able to see the points by looking directly down from on top of the switch unit with the cover off. There should be a 3 wire cord coming from the pump which will go in to one side of the switch and should hook up with one white wire to one of the screws on one set of points and the black wire to one of the screws on the other set of points. When the wire that comes from the breaker box comes in from the other side of the switch, it's hooked up to match the first set of wires, black with black, white with white. It really doesn't matter which goes on which side as long as they match. Then put both the grounds, whether they are green covered or just plain copper, to the green screw in the bottom of the switch. Turn on the breaker and it should start pumping provided it hasn't lost it's prime.

You gave no info about switch to help with wiring, but...
It is assumed it is a 125 volt single phase pump.
You have three wires in that case.
Black-(hot wire)
White-(neutral wire)
Green-(earth ground)
To switch any item using this type of set-up, you need to put the switch in line of the black wire.
Meaning, from the power coming to the pump, the white and green go straight to the pump.
the black goes to the switch. from the other side of switch to the pump.
You see? Simple.
Good Luck.

does the black go on the L1 or T1 ? Why is there only two wires when most have 4 ?
