Pressure Switch
Bendix

Pressure switch modules provide a precise electrical signal when hydraulic or pneumatic pressure reaches a defined threshold, enabling automated control of braking and auxiliary systems. This unit uses a 1/4-18 NPTF thread for secure, leak-free mounting and operates on a 12 V electrical supply with a current draw of 100 to 300 mA, making it suitable for integration with standard vehicle circuits without imposing undue load. Actuation pressure ranges from 63.00 to 77.00 psi, allowing tuning to specific braking system configurations and ride characteristics. The working temperature range spans 0 to 85 C (approximately 32 to 185 F), while the minimum and maximum operating temperatures extend to the vehicle’s hottest and coldest expected environments. A Packard 12065402 connector is specified for reliable harness mating, and a pre-applied thread sealant simplifies installation and ensures a durable seal. Used to trigger brake light activation or to interface with other control modules, this switch supports reliable, repeatable performance across a wide set of duty cycles and climatic conditions, contributing to fleet safety and automation reliability.
