Radium Engineering Adjustable Pressure Switch

Description

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 a ground or 12V signal as long as the other end of the low current relay coil wire is connected to an opposing source.
