1. When welding the light touch switch terminal, if a load is applied to the terminal, it may loosen, deform and degrade the electrical characteristics due to different conditions. Please pay attention to it during use.



2. When using through-hole printed circuit boards and circuit boards other than those recommended, due to the influence of thermal stress, please fully confirm the welding conditions in advance.



3. When welding twice, please do it after the first welding part returns to normal temperature. Continuous heating may deform the peripheral part, loosen and fall off the terminal and reduce the electrical characteristics.



4. As for the setting of welding conditions, it is necessary to confirm the actual batch production conditions.



5. The product is designed and manufactured on the premise of DC resistance load. When using other loads [inductive load, capacitive load], please confirm separately.



6. For the mounting hole and mode of printed circuit board, please refer to the recommended size recorded in the product drawing.



7. The switch shall be used for the structure of pressing the switch directly by people. Please do not use it for mechanical detection function.



8. The switch may be damaged if more than the specified load is applied when the switch is touched gently. Please be careful not to apply more than the specified force on the switch.



9. Please avoid pressing the operation part from the side.



10. For the flat shaft type, press the center of the switch as far as possible. For the hinge structure, the pressing position of the shaft rod will move when it is pressed down. Please pay special attention.



11. After the switch is installed, when it passes through the heat storage hardening furnace due to the binder hardening of other parts, please contact professionals.



12. If the materials around the whole machine using the switch produce corrosive gas, it may cause poor contact and other phenomena, so please fully confirm in advance.



13. The carbon contact point has the characteristic that the contact resistance changes due to the pushing load. When used in voltage divider circuit, please use it after full confirmation.

14. For models other than the closed type, please pay full attention to the intrusion of foreign matters.
