Description

The Wabco 4410060210 Stoplight Switch is a critical component within air brake systems, functioning as a valve to control the activation of stoplights on commercial vehicles.

Measuring 27 x 27 x 75 mm, this switch contributes to the safe and efficient operation of air brake systems.

Key Features & Benefits

This little guy basically tells your vehicle’s computer when you’re stopped. It does this by sensing when you hit the brake pedal, but only when the vehicle isn't moving. It sends a signal based on that information. It's a pretty simple component, really. Think of it as a messenger. It’s mainly used for things like automatic transmissions—telling the transmission to shift into park or neutral when you come to a stop. It also plays a role with some newer vehicles and their idle – stop systems, helping them turn the engine off at red lights to save fuel. Sometimes it’s even connected to the trailer brake supply relay, for vehicles towing. It's often found as part of the air brake system on bigger trucks and buses.

Symptoms, Risks & Replacements

If this switch goes bad, you'll notice if your vehicle doesn't shift smoothly or seems to "hunt" for a gear when stopping. On vehicles with automatic start/stop, the system might not engage or will do so erratically. Ignoring it can lead to transmission issues down the road, or in the case of trailers, a potentially dangerous loss of braking function. It’s a relatively inexpensive part, and often easy to replace. You can find them pretty easily at places like Fixparts Online, but if you’re not comfortable working on brakes yourself, it’s best to have a professional take a look.
