1. When soldering, the water-soluble flux may cause corrosion of the SIM card holder product, please avoid trial use.

2. When soldering the SIM card holder terminal, if a load is applied to the terminal, looseness, deformation, and deterioration of electrical characteristics may occur due to different conditions. Please pay attention during trial use.

3. Weld the tin twice before returning to the normal temperature after the first welding part. Continuous heating will deform the outer periphery of the SIM card holder, loosening the terminals, dropping off, and reducing electrical characteristics.

4. Set the welding conditions according to the actual mass production conditions.

5. Avoid flux flowing from around the printed circuit board to the SIM card holder.

6. This product is directly operated by humans. Please do not use it for mechanical testing.

7. For the printed circuit board mounting hole pattern, please refer to the recommended dimensions listed in the product drawing.

8, can not be cleaned.

9, MINI type SIM card holder products such as thin switches in the combined installation process, please be careful not to apply external force.

10. When using under low voltage conditions (below DC1V), there is a possibility of poor contact. When using this condition, please confirm it separately.

11. Please install the product with the mounting screws within the specified tightening force to avoid the possibility of thread damage.

12. This product is designed and manufactured on the premise of DC resistance and load. Please use other load (inductive load, capacitive load) to determine separately.

13. In the process of use and testing, if the load exceeds the specified load, the switch may be damaged. Please kept informed!

14. Install the product on the specified mounting surface and make the installation level. If it does not reach the level, it will cause malfunction.

15. If it is used in a dusty environment, dust will enter from the opening, causing contact failure or malfunction. Please consider it in advance when designing.

16. If it is used in a corrosive atmosphere, it may cause poor contact, etc. Please consider it before design.
