How to adjust Grudzia pressure switch sensitivity – pump won't start?

welcome

i have had a problem for a few days with the pressure switch at the wimest hydro from Przasnysz, when the water pressure drops the switch does not switch on the pump. However, it is enough to gently touch it and the jumper drops and the pump works. Probably a stone on the diaphragm is to blame, but I do not have the time to replace it yet and so the question is whether it is possible to "turn up" the sensitivity of the switch somehow?

thanks for your help

Circuit breakers generally have adjustable settings so they can be calibrated without any problem. If, on the other hand, you think there is contamination in the circuit breaker, you need to remove it, because now you will change the settings, and if the contamination washes out, the pressure can rise beyond the rated values and this can be dangerous.
