Pressure Switch, Valve
SAF-Holland

A valve-type pressure switch is a rugged sensing device used in trailer pneumatic systems to monitor and respond to air pressure changes. It provides a stable electrical signal when predefined pressure thresholds are reached, enabling automatic control of braking, suspension, or auxiliary systems. The design prioritizes repeatable operation under vibration, wide temperature ranges, and exposure to moisture, making it well-suited for over-the-road fleets facing diverse climates and road conditions. The VMRS code places this component within the trailer axle and suspension pressure sensing domain, facilitating proper interchange with compatible valve switches and controllers. Compatibility checks should include port sizing, electrical connector type, and pressure range. Documentation and safety labeling are standard, reflecting the importance of reliable sensing in critical braking and suspension functions.
