Vacuum Switch???

[horseballz]

Hi Guys,
As always, I'm looking fro an oddball needle in a haystack. I want to find a vacuum operated/actuated 12 volt switch. What I'm trying to accomplish is to have the circuit that activates the A/C compressor clutch open (turn off) under medium to hard acceleration/low vacuum. Adjustable would be best, but finding a source for the correct type of switch with different vacuums available would be OK, as I could (before purchase) run a vacum gauge into the passenger compartment to determine at what vacuum I want the switch to activate at. Any help and/or thoughts are appreciated.
TIA,
Gene

try snow water meth injection, I think their lower end unit uses an external switch like you are looking for; if not try some of the other meth inject companies.

The switch you're looking for is probably part of the 5000 series line made by Hobbs.
