Touch the use of the switch to pay attention to some details, below for you to introduce in detail.
Light touch switch is a kind of functional electronic switch, which belongs to the standard part. When using, it can be turned on by lightly pressing the switch button. When the hand is released, the switch will be turned off. Its internal structure is realized by the force spring of metal shrapnel.
1. When welding the light touch switch terminal, if the load is applied to the terminal, there may be looseness, deformation and electrical property degradation due to different conditions, please pay attention to it when using.
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. For two times of welding, please carry out after the first part of welding is restored to normal temperature. Continuous heating may cause deformation of the peripheral part, loosening and falling off of the terminal and decrease of the electrical characteristics.
4. For the setting of welding conditions, the actual batch production conditions need to be confirmed.
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. Please refer to the recommended size recorded in the product drawing for the mounting hole and mode of PCB.
7. The switch shall be used for the structure of pressing the switch directly operated by people. Please do not use for mechanical testing function.
8. The switch may be damaged if the specified load is applied when the switch is touched lightly. Please take care not to apply the above specified force on the switch.
9. Please avoid following the operation Department from the side.
10. For the flat shaft type, press the center of the switch as far as possible. For the hinge structure, when pressing, the pressing position of the shaft rod will move, please pay special attention.
11. After the switch is installed, please contact the professional when the adhesive of other parts hardens through the regenerative hardening furnace.
12. If corrosive gas is generated from the surrounding materials of the switch, it may cause poor contact, etc., so please fully confirm in advance.
13. The contact point of carbon has the characteristic that the contact resistance changes due to the push load. When it is used for voltage division circuit, please use it after full confirmation.
14. Please pay full attention to the invasion of foreign matters for models other than sealed ones.
