Can someone identify this ?

This is mounted on the first tank after the air dryer. It has a couple of wires going to it.

It is leaking air & before I can find a replacement, I need to know what it is . . . . 

Thanks!

Low air warning switch looks like to me it could trigger something else they are versatile for different applications check out Bendix numbers LP2 or LP3

hello;    You can remove it and check the wires with a meter.  Open or closed with no air pressure.. then add air to see when or if it closes or opens.. that will provide info on what it is.also you may find some numbers and a brand name which will point the way.
   just some info to help...

I'm with Cliff on this one. It looks like a low pressure sensor switch and I have had to replace several because they leak even though the switch still works. They're not that spendy online.

Thanks all !!!
Cliff was right, it was a LP-3. Napa was able to get one today. Only took 3 hours to change. I now know what the part is that they built the coach around!

It was almost impossible to see it while you were touching it.

Ironic that the low pressure switch is what was causing low pressure . . . .
