Dongfeng GX Steering column pneumatic adjustment switch C3404013-C6200

Exclusively designed for Dongfeng GX series commercial vehicles (including heavy-duty trucks and light buses), this switch strictly adheres to the original equipment (OE) specifications of part number C3404013-C6200. It matches the Dongfeng GX steering column’s pneumatic interface—with a 10mm air inlet port and standardized electrical connector (4-pin, IP67-rated)—ensuring seamless integration without modifications to the vehicle’s existing pneumatic or electrical systems. The switch is also compatible with Dongfeng’s latest GX models (2022-present), supporting both manual and semi-automatic steering column setups, making it a reliable replacement part for after-sales maintenance and factory assembly

Constructed with industrial-grade materials, the C3404013-C6200 switch exhibits exceptional durability to withstand harsh automotive conditions. Its housing is made of reinforced acrylonitrile butadiene styrene (ABS) plastic, which resists impact, high temperatures (operating range: -40°C to 85°C), and chemical corrosion from engine oils or cleaning agents. The internal valve core is crafted from brass, ensuring wear resistance and long-term airtightness—with a service life of over 100,000 adjustment cycles (equivalent to 5 years of typical commercial vehicle use). The switch’s button is coated with a non-slip rubber material, providing a comfortable grip and preventing wear even with frequent operation

Safety is a core focus of the C3404013-C6200 switch, featuring multiple protective mechanisms to avoid pneumatic or electrical malfunctions. It includes an overpressure relief valve that releases excess air pressure (above 1.0 MPa) to prevent damage to the steering column’s pneumatic cylinder. The electrical circuit is equipped with a short-circuit protection fuse (5A), safeguarding the switch and vehicle’s electrical system from current surges. Additionally, the switch’s airtight seal (IP6K9K-rated) prevents dust, water, and debris from entering internal components, ensuring reliable operation in dusty construction sites or rainy conditions. A built-in fault signal output also alerts the vehicle’s ECU to abnormal pressure or electrical issues, enabling timely maintenance

Engineered with driver comfort in mind, the C3404013-C6200 switch features an ergonomic design that enhances usability. Its control buttons are strategically positioned on the steering column’s side—within easy reach of the driver’s hands (no need to lean or stretch)—reducing distraction during adjustment. The buttons have a clear tactile feedback (click force: 3-5N), allowing drivers to confirm adjustment commands without visual checks. The switch also includes illuminated symbols (LED-backlit, red for tilting, blue for telescoping) that remain visible in low-light conditions (e.g., night driving or dark garages), improving operational clarity. Furthermore, it supports one-touch reset functionality, enabling the steering column to return to its default position with a single button press—ideal for multi-driver vehicle fleets
