I am looking for a pressure switch with the range of up to 100 psi. Single throw, dual pole. This will be a pneumatic application. 1/2 NPT would be great.

I would really like an integrated pressure gauge.

I have had really poor luck with anything labelled Ashcroft.

Any suggestions would be appreciated.
 
Wika has a solid state switch (PNP or NPN) with a digital display, but it requires DC power. Some particular function is not configurable via keypad, but I forgot which. There is some setup software but I'm not familiar with it.

United Electric has conventional blind electro mechanical pressure switches, like the H100, with no visual indication. You could pipe a pressure gauge to it on a Tee.

Square D is an industry standard for plain jane run of the mill pressure switches. Air compressors, well pumps, I see them everywhere. I would not hesitate to install a T and hang a gauge off one side and the pressure switch off the other.

I think we order ours from Grainger usually.
