square D pressure switch?

ok as i near the end of my parts list all i have left is 4 fittings and a pressure switch . My friend told me to use a  square d  witch i went to lowes and home depot and cant find them. Has anyone used these ?

I have had one on my car for a few years, never had any trouble out of it.

it's pretty much just like this one that air zenith sells. but i'm just using the 165/200 one that came with my viairs. http://www.waylayedinc.com/Waylayed2010/ww/products/Air-Zenith-Adjustable-Pressure-Switch.html#

i used mine for 6 years on 2 380s and not one problem only thing i will use

We use to carry the Square D's, but after I had (3) Square D's go bad in two weeks on my Trailblazer I quit carrying them and switched to Air Zeniths...Don't believe in selling something I myself wouldn't use
