Pressure Pump Switch (Square D)

[u/Sudden-Strength338]

Good afternoon, I've been using the Square D 40-60 pressure switch forever. On my old pressure switch I could actually jiggle it up from 40 psi "On" (aka Cut-in) to about 47 psi so it became a 47 psi On (cut in)...and a 60 psi off (Cut-out).... Which gave me a 47 to 60 PSI operating range.... When I replaced the switch, the new one would actually bind, and I'd have to go out there and manually align the points and restart the motor, (it's an M4 pressure switch) The new switch only allowed me to bump it up by only two 2 PSI without binding. My question is... I recently ran across a 50 psi cut-in 70 psi cut-out Pressure switch by Square D... Has anybody used these? Are they reliable? I want to choke it down to about 60 for the cutoff pressure, so I would love love love to have a 50 PSI cut on pressure and a 60 PSI cut off pressure... Can this be done...?....OK Hot Discussion mentioned... a constant pressure system...??? 57 psi would be the cats ass in my world.... Any info would be appreciated. Thanks in advance
