Waterproof and dust-proof characteristics of light touch switch
Release time：2018-09-04 Clicks： Click
Light touch switch can be waterproof and dust-proof, this feature is very practical, when using everyone should pay attention to.
Light touch switch is a basic component in many industries. Light touch switch can control the normal operation and stop of the whole product. So its quality is directly related to the quality of the whole machine. Once the performance of light touch switch is not good, people will be on the whole commodity. The quality of a complex electrical appliance is made up of the same pieces of components. Only by ensuring the quality of the product in detail can the quality of the product be maximized. Finally ensure the quality assurance of the whole product.
In recent years, the smartphone market is gradually expanding, smartphones began to appear in people's lives, different smartphones have different appearance and performance, give us a different sense of use, smartphones are divided into many classes and touch the switch, the price is also high and low, but when we use smartphones, The most frequently used parts are often ignored by us, that is, light touch switches.
As the name implies, a light touch switch is a switch that can be used as long as it is touched lightly. It takes no effort to press it. When we listen to a song, whether it is playing a track or adjusting the volume, we have to press this small switch by hand. Often the cheap smartphone buttons on the market are not very good, and it always comes out from time to time. Problem, everyone may have this experience in other small electrical appliances, they clearly pressed the switch but automatically operated twice, sometimes, how to press no response, this is the switch failure caused, we buy small electrical appliances, only pay attention to appearance and other performance, but always easy to ignore this not Starting switch, or actually buying a smartphone, electric shaver, touch the switch if the switch above the problem, then the entire electrical function can not play, the entire electrical operation system will be paralyzed because of this small switch.
There are many potential problems when we touch the switch with the patch, and some things we often overlook when using it. The following are some common problems when we touch the switch with the patch and some points needing attention when using it.
1. In the process of tap switch terminal welding, if the load is applied to the terminal, there will be loosening, deformation and deterioration of electrical characteristics due to different conditions, please pay attention to when using.
2. When using through-hole printed circuit boards and non-recommended circuit boards, the effect of thermal stress will change, so please fully confirm the welding conditions in advance.
3. When welding twice, please do it after the first welding part is restored to normal temperature. Continuous heating may cause deformation of the switch periphery, loosening of the terminal, shedding and reduction of electrical characteristics.
4, regarding 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 it separately.
6, printed circuit board installation holes and models, please refer to the recommended size in the product drawings.
7, switch should be used for direct operation by human, according to switch structure, please do not use mechanical detection function.
8. When the patch taps the switch, if more than the specified load is applied, the switch will be damaged. Please be careful not to apply the specified force on the switch.
9, please avoid using the operation Department from side to side.
10. For the flat shaft type, press the switch center as far as possible. For the hinge structure, the shaft will move when pressed. Please pay special attention.
