Waterproof light touch switch is a very popular switch in the market. It is deeply loved and trusted by consumers in the market. Do you know what light touch switch is? What is its principle? Here we can give you a detailed introduction, you can have a look.

Waterproof light touch switch is a switch that will not fail even if soaked in water or rain. Generally, the grade of waterproof switch is IP67, which means that it can play a good protective role against dust in the air, and can be maintained under water about 1m deep at room temperature for 30 minutes without damage. Therefore, it is well used in some wet places where waterproof switches need to be used.

The light touch switch is actually an electronic switch. In the process of use, in order to achieve the conditions of operating force, pressure is applied to the operating direction of the switch to achieve the closure and connection of the switch. When the pressure is cancelled, the switch will automatically open. Its internal structure realizes the closure and connection of the switch by relying on the changes in the metal shrapnel hand. The light touch switch is usually composed of insert, base, shrapnel, button and cover plate. For the light touch switch such as waterproof, a layer of polyimide film is added on the shrapnel.

Light touch switch is widely used in the market because of its small volume, small resistance, good hand feeling when pressing, complete types and sizes and so on. Like some automobile industry and information industry. Home appliances, medical equipment, monitoring and other industries have been applied.

The principle of the light touch switch is to make the internal shrapnel contact the three-point hardware at the bottom by touching the switch button, so as to turn on the switch. Once the button is manually turned off, the switch will be turned off immediately. We can know that the internal structure of the light touch switch is turned on and off by the force of the metal shrapnel.

We still have some matters to pay attention to when using the touch switch. When we weld the terminals of the light touch switch, if a load is applied to the terminals, looseness, deformation and deterioration of electrical characteristics may occur due to different conditions, so we need to pay attention to it when using. When welding twice, it should be carried out after the first welding is restored to normal temperature, otherwise continuous heating is easy to cause external deformation and loosening, falling off or reduction of electrical characteristics of terminals. When we operate the switch, we should be operated directly by people. Do not use any mechanical detection function, otherwise the switch will be easily damaged if a load is applied during the switch operation.

The above is the introduction to the waterproof touch switch. I hope it will be helpful to you.
