DeatschWerks 15 PSI 1/8-Inch NPT Hobbs Switch with Pigtail, DWK4-HOBBS-15

The DeatschWerks DWK4-HOBBS-15 Hobbs Switch is a dependable pressure-activated electrical switch designed for automotive applications that require a 15 PSI activation point. With a 1/8-inch NPT connection, it integrates easily into compatible air, boost, fuel, or fluid pressure systems when accurate pressure-based switching is needed.

This DeatschWerks Hobbs Switch includes a pre-wired pigtail to simplify installation and help reduce wiring time. The switch is rated for low-current applications up to 0.5 amp, making it well suited for triggering a relay, warning circuit, control module, or other compatible electrical device rather than powering high-current accessories directly. Its compact design supports installation in areas where space is limited, while the threaded connection provides a secure interface with properly matched fittings.
