The DeatschWerks 4-HOBBS-5 is a 5 PSI Hobbs pressure switch with an integrated pigtail, designed for boosted applications that require precise, pressure-triggered activation. Commonly used in turbocharged and supercharged setups, this switch allows you to automatically engage secondary fuel pumps, relays, or other accessories once the system reaches 5 PSI — ensuring proper fuel delivery and protecting the engine under high load.
Its compact, rugged construction and 1/8" NPT threaded fitting make it easy to integrate into fuel or boost pressure ports. With a 0.5A rating, it is ideal for low-current control circuits and staging logic in both street and motorsport environments.
