Can anyone suggest a good place to buy a hobb's switch for nitrous?

You should be able to find on in the Summit Racing catalog or at summitracing.com int he Nitrous section in the area where they have bottle warmers and gauges and bottle openers and such.
If not you can look to NAPA. They have several to choose from. There are ones set to different pressures and they are normally open or normally closed. You can pop out the little rubber plug in the end and insert an allen head wrench into the neck and adjust the pressure where the switch operates by turning the little plastic bolt down in side there. They are not called Hobbs Switches at NAPA. Go in and see if they will look up a pressure switch in the catalog so you can look at it and see what you want to get. I think one application is for an oil pressure switch on the big trucks. The price there was about $25.00
