Ii. Technical Specifications and Material Composition
This is a mechatronic component, with complex and precise materials and structure.
External housing and keys:
Material: Mainly high-strength ABS/PC engineering plastics are used to ensure durability and scratch resistance.
Surface treatment
Base: Usually Piano Black or dark metallic paint, with high gloss and fine touch.
Decorative strips: Plastic decorative strips made with vacuum chrome plating process enhance the sense of luxury.
Key ICONS: Utilizing light-transmitting laser engraving technology to ensure uniform and soft backlight.
Internal structure and electronic components:
Circuit board (PCB) : A printed circuit board made of FR-4 material, integrating a microprocessor and circuits, used to process switch signals and achieve intelligent functions such as one-click lifting.
Switch contacts: Usually gold-plated or silver-plated copper alloys are adopted to ensure excellent electrical conductivity and anti-oxidation ability, and to extend service life.
Backlight system: Equipped with built-in LED beads, it emits the standard white or ice white backlight of Mercedes-Benz, which is synchronized with the interior lighting system. The brightness often changes as the width indicator lights are turned on.
Connector: High-quality PA66 (nylon 66) material interface, with tin-plated or gold-plated copper terminals, ensuring reliability and corrosion resistance when connected to vehicle wiring harnesses.
