Product Description

The Radium 20-0236 Universal Adjustable Pressure Switch is a compact solution designed to trigger staged fuel pump activation or other pressure-based control events in performance fuel and engine systems. The pressure switch's set point can be adjusted between approximately 3 and 15 psi to match the desired activation threshold, making it suitable for boost-activated pump staging or other pressure sensing needs in custom installations.

Constructed with a stainless steel body and a standard 1/8" NPT male port, this switch installs into boost or fluid pressure lines where a pressure-based electrical trigger is needed. The normally open (N.O.) contact closes at the set pressure, allowing it to reliably trigger a low-current relay for device control. Included connector housing and pins allow basic wiring assembly for integration. While versatile for fuel, oil, or coolant pressure control, this switch is **not intended for brake system use**.

Its universal design makes the Radium 20-0236 adaptable to a wide range of automotive performance setups and custom builds - particularly in high-flow fuel system applications where pressure-activated control enhances reliability and safety. To ensure proper function and longevity, pair this switch with an appropriate relay and wiring strategy suited to your system's electrical requirements.
