Pressure Switch for booster pump

Right now I use a Square D pressure switch and I set it to 44 /67 psi
The switch is new ( one month old ) but I think I am using its rates max limits ( 66.7 psi is its max pressure limit) because I did not know at the time of purchase that I would need that pressure setting
The swich then jams often and keeps the pump running but it would kick out if I knock on a little knock
I will buy anothe one of higher pressure rates but I wonder if there is any DIGITAL pressure switches in the market , I think they would be much easier in the setting and adjustement
Any advice?
Thanks very much in advance

Thank you very much , it is very interesting !

Square d makes many versions of switches, some with fixed differentials that take guess work out of set up. Look at Graingers under well AND compressor pressure switches, there must be 30+ variations under 50 bucks.
