Steering system
The left combination switch assembly (Part No.: 3774020-C6200) is exclusively engineered to match the electrical system and structural design of Dongfeng GX series vehicles. It undergoes strict fitment testing to ensure seamless alignment with the vehicle’s steering column, eliminating issues like loose installation or mismatched connectors. This exact compatibility guarantees that all switch functions interact perfectly with the vehicle’s ECU (Engine Control Unit) and electrical modules, avoiding signal interference or functional failure
Product Attributes
Warranty: 1 YEARS ,Part name: Combination switch assembly 3774020-C6200
PRODUCT DESCRIPTION
Multi-Functional Integration: Centralized Control for Driving Operations
This assembly integrates multiple essential driving controls in one compact unit, including headlight on/off, high/low beam switching, turn signal activation, and windshield wiper/washer control. Each function is assigned to ergonomically designed buttons and levers, with clear tactile feedback to help drivers operate without taking their eyes off the road. The logical layout of controls follows Dongfeng’s standard human-machine interface (HMI) design, ensuring familiarity for existing Dongfeng GX drivers and reducing learning costs
High-Durability Materials: Resistant to Wear and Harsh Environments
The outer shell of the switch assembly is made of high-grade ABS plastic with anti-aging and impact-resistant properties, capable of withstanding long-term exposure to sunlight, high temperatures, and humidity in the engine compartment. Internal electrical contacts adopt silver-plated copper alloy, which enhances electrical conductivity and prevents oxidation or corrosion—extending the switch’s service life to over 50,000 operation cycles. All materials comply with automotive industry RoHS standards, ensuring environmental friendliness and safety
Strict Safety Compliance: Meeting Automotive Electrical Standards
The 3774020-C6200 switch assembly passes rigorous safety tests, including overcurrent protection, short-circuit prevention, and insulation resistance verification. It meets GB/T 18487.1 (China’s automotive electrical safety standard) and ISO 16750 (international automotive electronic equipment standard), ensuring no electrical leakage or fire hazards during use. Additionally, the switch’s lever has a built-in anti-fatigue structure, preventing accidental operation caused by vibration during driving
Easy Installation & Maintenance: Reducing Repair Time
The switch assembly adopts a plug-and-play design, with a connector that matches the original Dongfeng GX wiring harness—no cutting or rewiring is required during installation. The compact size and lightweight (only 120g) allow it to fit into the limited space of the steering column without modifying surrounding components. For maintenance, the assembly’s modular structure enables quick disassembly of faulty parts (e.g., buttons, contacts) without replacing the entire unit, significantly lowering repair costs and downtime
