Relays & Switches: DeatschWerks Hobbs Pressure Switches

Relays and pressure switches let a low current signal control a high current load, which is the foundation of staged fuel pump wiring, warning lights and boost triggered accessories. A pressure switch opens or closes a circuit at a set pressure, so it can turn on a second fuel pump, a shift light or an alarm exactly when boost or oil pressure reaches a target.

This collection currently holds DeatschWerks Hobbs pressure switches with 1/8in NPT threads. We carry fixed 5 PSI and 15 PSI switches plus adjustable versions covering 1 to 3 PSI and 8 to 12 PSI. They are a popular way to stage a second fuel pump on a dual pump setup, triggering a relay so the extra pump only runs under boost. We do not list standalone relays here right now, so pair these switches with a relay that matches your pump's current draw.

OneFastShop is an authorized DeatschWerks dealer, and every switch is genuine with full manufacturer warranty. Need help with a staging setup? Contact our team.
