Overview

DeatschWerks Hobbs Switches

DeatschWerks Hobbs switches are adjustable, pressure-activated electrical switches designed to trigger secondary systems—such as fuel pumps, nitrous systems, or warning lights—based on intake manifold boost pressure. They're crucial for high performance, forced-induction vehicles to ensure adequate fuel delivery, preventing engine lean-out by activating additional pumps only under boost. The switches are available in a variety of pressure ranges.

Additional details:

* Functionality: Normally open (or closed) switches that activate at a specific, adjustable pressure threshold
* Components: Feature a durable, corrosion-resistant metal body with a standard 1/8 in. NPT threaded connection for mounting
* Installation: Included pigtail wiring harness simplifies integration into vehicle electrical systems
* Versatility: Suitable for various automotive applications, Hobbs switches help manage electrical load by keeping secondary systems off during low-demand, vacuum-driven driving
