When installing light touch switch, we should pay attention to welding problems. What problems should we pay attention to when welding? Let's give you a detailed introduction.
Touch switch, as its name implies, is an electronic switch, which belongs to the category of electronic components.
In addition, the light touch switch, also known as the key switch, first appeared in Japan when it was used to satisfy the operating conditions and close the pressure switch function in the direction of switching operation. When the pressure was withdrawn, the switch was disconnected. Its internal structure was realized by the force change of metal fragments.
1. For the setting of welding conditions, it is necessary to confirm the actual batch production conditions.
2. When welding twice, please do it after the first welding part is restored to normal temperature. Continuous heating may deform the periphery, loosen the terminals, drop off and reduce the electrical characteristics.
3. When welding lightly touched switch terminals, if the load is applied on the terminals, there will be loosening, deformation and deterioration of electrical characteristics due to different conditions. Please pay attention to the use.
4. When using through-hole printed circuit boards and PCBs other than those recommended, due to the change of thermal stress, please confirm the welding conditions in advance.
