Volvo Pressure Switch
Volvo

Pressure switches play a critical sensing role in Volvo truck systems, converting the pressure in hydraulic, fuel, or air circuits into a dependable electrical signal that enables or limits specific functions. This sensor is built to survive the rugged environment of a heavy-duty engine bay, featuring a sealed body, rugged connectors, and corrosion-resistant materials designed to resist road spray, brake dust, and vibration. When installed, it feeds accurate setpoints to the engine control module or brake controller, allowing precise regulation of fueling, transmission shift logic, or safety interlocks. The result is steadier engine response, reduced risk of over-pressurization, and more consistent performance under heavy loads. The compact footprint makes it straightforward to deploy in space-constrained manifolds or rail assemblies, while the electrical terminals provide robust, low-resistance connections that stay reliable across temperature swings. Regular inspection of the connector pins and visible seals helps prevent intermittent signals that could trigger warning lights or mismanage system pressure. Fleet operators benefit from fewer diagnostic cycles and faster problem resolution. Available through Source One Parts Center.
