Jabsco 40 PSI Pressure Switch Kit

Replacement Jabsco Par-Max Pump Pressure Switch. 40 psi pressure switch suits the Jabsco Par-Max Plus 3.5 (12V J20-108 and 24V J20-109).

Failure of a caravan style water pump can usually be attributed to the pressure switch. Designed to regulate the delivery pressure, the switch works by turning the pump off when the set pressure is reached, and turns the pump back on again if the pressure drops. 

We have many different styles of Jabsco pressure switches available but not all listed in the store. Drop us a line with the exact Jabsco pump make and model and we'll get back to you with the correct new pressure switch required for your pump.
