## Questions & Answers

**Q: What PSI range can the switch be adjusted to?**
A: This switch is considered non-adjustable. It comes set at 20psi. Not sure if the top can be opened and modified.

**Q: Can this be set to 5 psi nc? if not do you know which model does?**
A: I have mine used to shut off fuel pump if there’s a oil pres. failure it’s set at 12 lb. It appears like there’s enough travel to get it down much more. I hope this helps

**Q: what is the working voltage of this switch?**
A: I don’t think the voltage is relevant,  i.e will work with any voltage, the amperage Is the important factor.  This pressure switch should only be used to switch a relay to protect the contacts inside.

**Q: What is the wiring schematics?**
A: It is single pole double throw which means it has a common plus one normally open and one normally closed contact. There is no schematic; it’s a simple switch
