In the interior upgrade of the 2023 model of the Chrysler Group, three core requirements were proposed for the makeup mirror system:

1. Achieve intelligent linkage between the mirror cover opening/closing and the lighting system

2. Enhance the operation feel to the standard of luxury vehicles

3. Pass the most stringent automotive electronic reliability tests in North America.

II. Technical Challenges

1. Space Conflict: The thickness of the mirror cover is only 8mm, and traditional switches cannot be installed.

2. Touch Sensitivity Issue: A trigger with an ultra-short stroke of 0.5mm is required.

3. Noise Reduction Requirement: The operating noise must be controlled below 25 decibels.

4. Extreme Environments: It needs to withstand temperature fluctuations ranging from -40℃ to 105℃. 

III. Performance Parameter Comparison

| Index     | Industry Standard | G304A   | Enhancement Ratio 

| Mechanical Life | 30,000 times | 100,000 times | 233%    

| Trigger Force Deviation | ±0.5N | ±0.1N | Accuracy Improved by 5 times

| Operating Temperature Range | -30~85℃ | -40~125℃ | Expanded by 50%   

| Response Time | 5ms | 1ms | Speeded up by 80%   

IV. Application Results

1. Intelligent Interconnection:

Instant illumination upon lid opening (delay < 10ms)

Supports multi-level brightness memory function

2. Quality Enhancement:

User satisfaction rate increased to 98.7%

3. Reliability Verification:

Complies with the North American USCAR-2 vibration test standard

Salt spray test lasted for 1000 hours without failure  

V. Customer Value

1. Saves 40% of installation space, facilitating the design of a lightweight interior

2. Reduces the post-sale failure rate to 0.001 times per thousand units
