New Energy Power parts
This mechanical power switch assembly (Part No.: 3736010-TL770) is exclusively designed for new energy vehicles (BEVs/PHEVs), supporting high-voltage NEV power systems (compatible with 200-400V DC, matching mainstream NEV battery pack voltage ranges). It aligns with NEV electrical architecture standards, featuring a dedicated high-voltage connector (IP67-rated, 3-pin design) that directly interfaces with the vehicle’s power distribution unit (PDU) and battery management system (BMS). The switch’s internal current-carrying components are optimized for NEV high-current demands, ensuring seamless integration without voltage conversion or adapter use

PRODUCT DESCRIPTION
Robust Mechanical Operation & Long Durability
Equipped with a precision mechanical toggle mechanism (made of hardened stainless steel), the switch offers clear on/off positioning with a tactile "click" feedback—preventing accidental activation or deactivation due to vehicle vibration (frequency: 10-500Hz). The contact points are plated with silver-nickel alloy (plating thickness: ≥5μm) for low contact resistance (≤20mΩ) and excellent wear resistance, supporting over 10,000 switching cycles (twice the industry average for NEV power switches). The toggle lever is made of high-impact PA66 plastic (surface anti-slip texture) that withstands -40°C to 85°C temperatures, avoiding brittleness or deformation in extreme environments
Multi-Layer High-Voltage Safety Protection
Tailored for NEV high-voltage scenarios, the assembly integrates multiple safety features: high-voltage isolation (insulation resistance ≥100 MΩ at 500V DC) to prevent electric shock, and an over-current protection mechanism (limits current to 100-150A, matching NEV power load requirements) that disconnects the circuit in case of overload. The switch housing is made of flame-retardant PC material (UL94 V-0 rating) that resists ignition and inhibits flame spread, critical for NEV fire safety. Additionally, the high-voltage connector includes a mechanical interlock—only allowing disconnection when the switch is in the "off" position, avoiding arcing during maintenance
Space-Saving Design & Easy NEV Installation
The switch adopts a compact structure (dimensions: 60×40×30mm) to fit tight NEV cabin or PDU mounting spaces, with a lightweight aluminum alloy base (weight: ≤100g) that reduces vehicle load. It features a snap-on + bolt-fixed dual-installation design: pre-installed elastic clips enable quick positioning on NEV mounting brackets, and 2 M4 stainless steel bolts (matching original NEV thread specifications) ensure secure fixation. The 0.8m-long high-temperature silicone wire (rated for 150°C) allows flexible routing to the PDU, and the switch is marked with clear "ON/OFF" labels (UV-resistant printing) for intuitive operation. Installation can be completed in 8-12 minutes with basic tools, no specialized calibration required
TECHNICAL SUPPORT
1. Accessories selection consultation
- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.
The technical team is available online 7×12 hours to answer technical questions about accessories (such as material compatibility and installation processes).
2. Customized development support
We offer specialized R&D services for special market demands (such as heat dissipation accessories for high-temperature regions in the Middle East and dedicated suspension components for road conditions in Africa), and complete sample delivery within six weeks.
3. Training and Technical materials
Provide remote/on-site training for the customer's after-sales team (such as diagnosis of electrical control accessories and DPF regeneration operation), along with multilingual versions of the "Accessories Installation Manual" and "Troubleshooting Guide".
4. Quality Traceability and Improvement
Through the QR code traceability system (one product, one code), track the production batch of accessories and the source of raw materials, respond quickly to quality complaints and initiate improvement processes.
AFTER-SALES AND LOGISTICS SUPPORT
After-sales service
Quality Assurance Policy
-The warranty period for original factory parts is 12 months (counting from the date of signature for receipt), covering material defects, process issues, and man-made damage.
- Provide "Localized Express repair Service" : Cooperate with third-party repair networks in markets such as Southeast Asia and the Middle East, and deliver emergency parts to designated repair points within 4 hours.
Return and Exchange Process
-The customer is required to submit the test report (such as a third-party appraisal) within the warranty period. After confirmation by Dongfeng, a reissue or refund will be arranged within 5 working days.
Logistics support
Warehouse Layout
-Five major regional accessory centers have been established globally (Southeast Asia, the Middle East, Africa, South America, and Europe) to achieve "next-day delivery" for mainstream accessories (covering customers within the regions).
Emergency Logistics Plan
-Emergency parts can be directly delivered within 48 hours via the "Dongfeng Exclusive Aviation Special Line" (such as engine ECU, brake valves and other key components).
Packaging Optimization
-Use shockproof and moisture-proof packaging (such as honeycomb cartons + pearl cotton), and reinforce fragile parts (such as glass, sensors), keeping the damage rate within 0.5%.
