Pressure switch brand?

[Marksreef]

I need a pressure switch that Avast sells for their ATO’s and skim lockers.
They are currently out of stock and that leads me to wonder if anybody else sells them for other things, maybe at a cheaper price? Anybody know of other brands?

Hmmm... I haven’t seen anyone that sells them for our use. I imagine it is just a regular air switch in there. Would be low pressure though.
