Release time:2021-06-10

Notes for operation when using the SD card socket:

1. When soldering, water-soluble flux may cause corrosion of this product, please avoid trying it.

2. When soldering the terminals, if a load is applied to the terminals, there may be loosening, deformation and deterioration of electrical characteristics due to different conditions. Please pay attention during the trial.

3. Please solder twice after the first soldering part returns to normal temperature. Continuous heating may deform the peripheral part, loosen the terminals, fall off, and reduce electrical characteristics.

4. The welding conditions should be set according to the actual mass production conditions.

5. Avoid flow of flux to the product from around the printed circuit board.

6. This product is directly operated by humans, please do not use it for mechanical detection functions.

7. Please refer to the recommended size described in the product drawing for the hole position pattern of the printed circuit board.

8. Can not be cleaned.

9. For MINI products such as thin switches, please be careful not to apply external force during the assembly installation process.

10. When used under low voltage conditions (below DC1V), there may be poor contact. Please confirm separately when used for this condition.

11. Products with mounting screws should be carried out 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 confirm separately when using other loads (inductive load, capacitive load).

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

14. Please install the product on the specified installation surface, and make the installation reach a level state, if it does not reach the level state, it will cause malfunction.
