Product Details and Specifications

The PS-390 air brake pressure switch from Standard Ignition features a single male screw terminal designed for reliable electrical connection without the need for a connector. This design reduces potential points of failure and simplifies installation in air brake systems. The absence of a connector allows for direct wiring, which is common in many Freightliner and Kenworth air brake assemblies. The switch is engineered to monitor air pressure levels accurately, triggering signals that help maintain proper brake function and safety.

Applications and Problem Solving

• Monitors air pressure in commercial truck air brake systems
• Prevents brake failure due to low air pressure
• Ensures timely activation of warning indicators on Freightliner and Kenworth vehicles
• Helps maintain compliance with safety regulations for heavy-duty trucks
• Replaces faulty or worn air brake pressure switches to restore system reliability

Installation Notes and Tips

When installing the Standard Ignition PS-390, ensure the screw terminal is securely fastened to prevent loose connections. Since this switch does not include a connector, verify that wiring is compatible with a male screw terminal setup. It is recommended to consult the vehicle’s service manual for specific air brake system wiring diagrams, especially for Freightliner and Kenworth models, to ensure proper integration.
