Product Overview
This product is an automotive charging indicator lamp with a press-type operation, designed for status indication and user interaction. Developed based on in-vehicle usage conditions and operating frequency, the structure combines upper and lower PC components with a silicone intermediate connector, achieving a stable appearance, reliable tactile feedback, and long mechanical service life.
Structural Characteristics and Component Layout
The indicator features a two-piece PC structure, consisting of an upper translucent press cap and a lower supporting housing. A silicone connector is positioned between the two components to provide elastic movement and return force. The axial load path is clearly defined, helping maintain smooth and stable motion during repeated pressing without misalignment or jamming.
Material Configuration and Pressing Durability
Both the upper and lower components are molded from PC (polycarbonate), offering good structural strength and dimensional stability. The intermediate silicone part provides cushioning and rebound during operation. With optimized silicone hardness, travel, and load distribution, the structure achieves a pressing life of over 800,000 cycles under normal operating conditions, making it suitable for high-frequency automotive use.
Mold Design and Molding Control
To support multi-material integration and long service life, the mold design focuses on the dimensional accuracy of each component and a stable interface fit during assembly. PC and silicone parts are molded separately to ensure consistent quality and reliable assembly, forming a solid foundation for overall durability and repeatable production performance.
Application and Integration
This charging indicator lamp is suitable for automotive charging systems that require reliable operation and extended service life. The structure can be adapted to different vehicle layouts and appearance requirements while maintaining mold manufacturability and stable mass production, supporting long-term project deployment.
