Can you make a hobbs pressure switch work backward?
If i understand correctly, a pressure switch is used to prevent the NOS from switching on if the fuel pressure is below a certain point. I get the impression that the circuit to the arming switch (or something) is opened by the pressure switch. Well I want a pressure switch to close a circut. I need to figure out how to make an electric vacuum pump activate when the vacuum drops below a certin point. Any suggestions?
