Product details
This is the Hydroquip replacement pressure switch, part number 34-0019-C, listed by Hydro-Quip as the 4037P. It is a straight replacement for the original switch.
What a pressure switch does
A pressure switch is a simple thing with an important job: it senses whether there is pressure in the line and opens or closes a set of contacts accordingly. That signal is what tells the rest of the system it is safe to run. When the switch sticks or its contacts stop making, equipment either refuses to start or fails to shut down, and the fault is easy to misread as a bigger problem.
Before you order
Pressure switches from different makers look very similar. Read the number on the body of the one you are replacing and confirm it against 34-0019-C or 4037P.
