Where can I get a hobbs switch?

I am looking to make my own CO2 i/c sprayer. It cant be that hard. Just don't know where I can get a low pressure hobbs switch normally open. I would like to have adjustment from 0 to 20 psi. The rest sould be pretty simple. I will have to make a sprayer for the i/c but then I can make it big enough for the ford i/c. The rest I can get at a industrial suppier.
