We need to understand the selection and use of touch switches, so that we can find some problems in the actual use, of course, the problems we know in the ordinary day can also be used, the following on this issue for you to better introduce.

The quality of the switch will directly affect the use of the product. Therefore, when selecting the light touch switch, we should pay attention to its solderability, protection, conduction and other physical properties. Its service life is long, and whether the touch is rough or not. These external surface factors will also determine the quality of the light touch switch. In order to reduce the resistance, silver plating will be used on the pins, so the high quality light touch switch should be controlled in the thickness and process of silver plating on the pins. The final silver plating is above 0.3um, thin silver is 0.2um, and 0.1um is white plating. Four feet touch switch after silver plating, whether its protection has waterproof and dust-proof function, otherwise the best silver plating treatment, will be oxidized by air!

For the welding of the switch, it is necessary to confirm the conditions at the time of production. Because of the different conditions, the conformity imposed on the terminals and the deterioration of deformation are also possible, so we must pay attention to this point in use. For the influence of thermal stress of lightly touched switch, it is necessary to make full confirmation before use; after the first welding process, the second welding should be carried out under normal temperature after the first welding. If heated continuously, the shape of lightly touched switch will be changed, and the terminal may fall off, resulting in the reduction of electrical characteristics. The resistance load of the light touch switch is designed on the premise. When using other loads, please pay attention to the confirmation.

This is how to select and use the light touch switch. Please have a better understanding and understanding when using it.
