VDO Heavy Duty Normally Open–Single Circuit 4 PSI Pressure Switch

The VDO Heavy Duty Normally Open–Single Circuit 4 PSI Pressure Switch is an essential component for marine engine monitoring and fuel system management on both recreational and commercial vessels. This pressure switch is designed to activate at 4 PSI, making it suitable for low-pressure applications such as fuel pump cutoff systems and engine oil pressure alerts.

Constructed to VDO's high standards, this switch offers reliability that marine technicians and boaters require for accurate system response. Its normally open, single-circuit design ensures that the circuit remains open until pressure reaches the 4 PSI threshold, effectively minimizing false alarms from minor pressure fluctuations while still being sensitive to significant changes.

Marine mechanics, boat builders, and engine technicians depend on this pressure switch for safety and diagnostics in various marine applications, including cruisers and fishing vessels. Its heavy-duty construction is built to withstand the corrosive and vibration-intensive marine environment, ensuring durability and performance.
