6. Precautions for Use
1. Environnement: Avoid installation in areas directly exposed to rain, strong magnetic fields, or near objects with thermal radiation.
2. Density: Avoid excessive bulk density in use, which may affect the electrical characteristics of the switch.
3. Mechanical Shock: Excessive mechanical shock strength may change its magnetic sensitivity or even damage the switch.
4. Soldering: Use appropriate pin tightening or heat dissipation to prevent mechanical or thermal stress during welding.
5. Welding Parameters: The maximum welding temperature is 260°C and the time is less than 5 seconds.
