This Adjustable Pressure Switch offers a solution for triggering staged fuel pump(s) based on positive boost pressure. This normally open (N.O.) switch features a 3-15psi adjustable set point to match any application. The stainless steel body features a 1/8" NPT male port. Connector and pins are included (assembly required). This switch ONLY activates with positive pressure.INSTALLATION NOTES:-DO NOT route the main power for a fuel pump through this switch. Use the switch to trigger a relay.-This switch may be used to trigger any device, not just a fuel pump, as long as the current demand is less than 0.5 Amp.-Review the installation instructions in the above link prior to purchasing.-The switch DOES NOT come pre-set to any particular pressure, it MUST be calibrated using the method outlined in the installation instructions.-This switch may also be used in other fluid applications (oil, fuel, coolant, etc). DO NOT use with brake fluid.
NOTE: the relay "trigger" signal that goes through the adjustable pressure switch can be a ground or 12V signal as long as the other end of the low current relay coil wire is connected to an opposing source.
