This Wabco pressure switch (MPN: 4410140130) is a critical component within air brake systems, functioning as a safety and control device. It is designed for use in commercial vehicles and industrial applications where reliable pressure monitoring is essential. This normally closed switch activates when pressure falls below a set point, triggering alerts or safety mechanisms. Measuring 25 x 42 x 27 mm, it features a 12/24V electrical connection with Tab 6.3 x 0.8 IEC - 60760 CuZn37, gal . Ag connectors and M12 x 1.5 port threads. Its robust design, operating within a temperature range of -40°C to +80°C and a maximum operating pressure of 12.0 bar, ensures consistent performance and longevity. The switch pressure is set to 4.1±0.4 bar.

Key Features & Benefits

Basically, this little guy monitors the air pressure in your brake system. It’s an electrical switch that activates or deactivates based on whether the air pressure hits a specific level. It doesn't do the braking itself, it just tells other parts what’s going on with the air pressure. It’s a signal sender, if you will. Some have adjustable settings, some are preset. Think of it as part of a system of checks and balances for your air brakes. It’s often linked to things like your parking brake, or a warning light on the dash. It might also be involved in applying the spring brakes if the air pressure drops too low while you're driving—a safety feature. It’s used in a lot of heavy – duty trucks and trailers, anything that relies on air brakes. It’s usually mounted near the air tanks or relay valves.

Symptoms, Risks & Replacements

It’s pretty critical, honestly. If this switch fails, you might not get a warning when your air pressure is getting low. That can lead to serious issues—you might not realize your brakes aren't fully functioning. It’s a key piece in keeping the entire system working safely and effectively. You’ll notice if it goes bad – usually a warning light staying on when it shouldn’t, or not coming on when it should. You can find a good selection of these at places like Fixparts Online, and they're relatively straightforward to replace if you’re comfortable with basic brake system work. But if you’re at all unsure, it’s best to have a pro take a look.
