## Questions & Answers

**Q: Will these 12volt pressure switches work on a 120volt electric compressor ?**
A: No

**Q: Is this waterproof?**
A: To an extent, is your connector water proof?

**Q: Just to be sure, as it is 70/100, if I want to use for anything pressured less than 70, will it stop at 70 not letting me keep running?**
A: the pressure will stop between 70-100 mine stops around 80 they do make them to a lower pressure.

**Q: Can you wire this to the power switch on a portable 12v air compressor so that it will kick off automatically between tires, or does it need a relay?**
A: Previous answer is not correct. You can wire this in series with the on/off switch of the compressor and it will work.  That is exactly the purpose of the switch. The on/off switch is connected to a control board which is low power. The relay for the compressor motor (which is the high power draw) is built into the controller.
