## Questions & Answers

**Q: does this item come with the clear tubing and spigots?**
A: Yes it does

**Q: I am looking for a service that will enable a push button only if the air pressure is above 50psi.  Could this help?**
A: Push button? For LF32 switch, there is no button, only a knob in middle of the switch. You can turn the knob no matter whatever pressure it is..

    Great pressure switch
  

*by A***R on Reviewed in the United Kingdom on 8 July 2022*

Used to detect loss of air pump pressure on a koi bio filter.  Had an experience where air pump failed and didn’t notice.  This solves that problem, and can use the output from this switch to create alerts to tell me if there is a failure.  Works perfectly 👍
