Product Introduction

• Structure: Precision-molded from high-quality ABS plastic with a matte black finish that matches the overhead console and interior trim. It features an integrated snap-fit mounting structure, a precisely sized cutout for the sunroof switch, and reinforcing ribs for structural rigidity. The frame also includes a dust seal around the switch cutout.

• Performance: The robust ABS construction resists warping and cracking from temperature changes and vehicle vibration, while the matte finish resists scratches and UV fading. The dust seal prevents debris from entering the console through the switch gap, maintaining the cleanliness of the internal electrical components.

Core Function

1. Switch Mounting & Stabilization: Provides a secure, stable mounting platform for the sunroof switch, preventing it from loosening or rattling due to vehicle vibration.

2. Dust & Debris Protection: The integrated dust seal blocks dust and small particles from entering the overhead console, protecting the internal wiring and electrical components.

3. Interior Aesthetics: The matte black finish and contoured design blend seamlessly with the overhead console, maintaining a clean, unified appearance of the cab interior.

Customer Case Study: Switch Frame 812W25503-5001 Bulk Supply to East Africa

In early 2024, a fleet maintenance company managing 120+ Sinotruk Sitrak tractor units in Tanzania reached out to Mettlead. Their problem was straightforward but costly: cracked and sun-damaged switch frames were causing switch modules to detach during operation, leading to driver complaints and safety write-ups during inspections.

After verifying the OEM number — 812W25503-5001 — our team shipped an initial sample batch of 10 units for fitment validation. The client confirmed perfect compatibility across their C7H fleet within two days. Subsequently, they placed a standing quarterly order of 200 pieces, packaged under their own workshop brand.

The result? A 28% reduction in per-unit cost compared to their previous sourcing channel, zero fitment rejections over three shipments, and delivery within 5 business days to Dar es Salaam via sea-air hybrid logistics. Today, this customer sources over 35 different Sitrak cab components exclusively through Mettlead.
