1. When welding the waterproof switch terminal, if the terminal is loaded, there will be looseness, deformation and poor electrical performance due to different conditions. Pay attention when using it.

2. When using through-hole printed circuit boards and other recommended circuit boards, due to the influence of thermal stress, it will change, so please fully determine the soldering conditions in advance.

3. When welding twice, please restore the first welding part to normal temperature. Continued heating will deform the periphery, the terminals will loosen, fall off, and the electrical characteristics will be degraded.

4. Regarding the setting of welding conditions, it is necessary to confirm the conditions of actual mass production. The product is designed and manufactured on the premise of DC resistance loading. Please confirm the use of other loads [sensitive load, capacitive load] separately.

5. For the mounting holes and methods of the printed circuit board, please refer to the recommended dimensions listed in the product drawings.

6. If too much load is applied to the waterproof switch, the switch may be damaged. Remember not to apply more than specified force to the switch. Also, please do not hold down the operator's hand from the side.

7. For the flat shaft type, try pressing the middle part of the switch. In the hinge structure, when pressing the shaft, pay special attention to the position of the pressing shaft.

8. After the switch is installed, if it passes through the regenerative hardening furnace due to the hardening of the adhesive of other parts, please contact the professionals.

9. If the material around the switch is used to generate corrosive gas, it may cause poor contact and other phenomena, so it must be fully confirmed in advance.

10. The carbon contact point has the characteristics of different contact resistance due to the thrust load. When used in a voltage divider circuit, etc., please confirm before use.

So today's explanation will come here first. The above is the whole content of today. I believe that everyone has a certain understanding of the precautions when using the waterproof switch. Thank you very much for your patient reading. If you want to know more about the waterproof switch, you can call the service hotline in the upper right corner to consult with us.
