Tact Switch

Product Details

Precautions when using the touch switch

1. When soldering the terminal of the tact switch, if a load is applied to the terminal, there may be loosening, deformation and deterioration of electrical characteristics due to different conditions. Please note when using it.

meaning.
2. When using through-hole printed circuit boards and non-recommended circuit boards, due to the effect of thermal stress will change, so please fully confirm the soldering conditions in advance.
3. When welding twice, please do it after the first welding part returns to normal temperature. Continuous heating may deform the periphery, loosen terminals, fall off, and electrical characteristics.
Sexual decrease.
4. Regarding the setting of welding conditions, it is necessary to confirm the actual mass 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. Please refer to the recommended dimensions in the product drawing for the mounting holes and patterns of the printed circuit board.
7. The switch should be used in a structure where the switch is directly operated by humans. Do not use it for mechanical detection functions.
8. When operating with a light touch switch, if a load above the specified level is applied, the switch may be damaged. Be careful not to apply more than the specified force on the switch.
9. Please avoid the usage of pressing the operating part from the side.
10. For the flat shaft type, try to press the center of the switch. For the hinge structure, the pressing position of the shaft will move when pressed, please pay special attention.
11. After the switch is installed, please contact a professional when passing through the regenerative hardening furnace due to the hardening of the adhesive of other parts.
12. If corrosive gas is generated from the surrounding materials of the whole machine using the switch, 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 pressing load. When used in a voltage divider circuit, etc., please use it after sufficient confirmation.
14. Regarding models other than the enclosed type, please pay attention to the intrusion of foreign matter.
