注意事项 PRECAUTIONS

1 Installation: Ensure proper alignment of through-hole terminals with PCB holes before soldering; handle the cap carefully to avoid damage during installation

2 Soldering: Follow specified parameters—IR reflow max temperature of 260°C for 5 seconds, manual soldering max temperature of 350°C for 3 seconds—to prevent switch or LED damage

3 LED protection: Avoid static discharge when handling the switch to protect the integrated red LED; ensure correct polarity connection for LED functionality

4 Operation: Do not exceed the actuator strength limit of 2.5Kgf to prevent mechanical damage

5 Storage: Store in a dry, dust-free environment within the range of -30°C~+80°C; avoid exposure to moisture or corrosive gases

6 Maintenance: Do not disassemble the switch manually; clean with a dry soft cloth if needed, avoiding liquid cleaners
