Waterproof tact switch is a kind of even in the water or is soaked in the rain but it wouldn’t switch failure, the level of waterproof switch is IP67 level normally, this meaning is refers to the ability to have very good protection effect, the dirt in air and at room temperature about 1 meter deep underwater can maintain 30 minutes will not be damaged. Therefore, it is well used in some wet places where waterproof switches are needed.
Waterproof tact switch, in fact, a kind of electronic switch, in the process of use in order to meet the conditions of the operating force in the direction of switch operation pressure switch to off and on, when pressure is revoked after switch will automatically disconnect, the internal structure of it is done by relying on the change of metal shrapnel hand switch is closed and connected. The touch switch usually consists of insert, base, shrapnel, button and cover plate, etc. Among them, the touch switch, such as waterproof, adds a layer of polyimide film on the shrapnel.
There are some other considerations when using the waterproof TACT switch. When we are welding the terminal of the light touch switch, if the load is applied on the terminal, it may be loosened, deformation and electrical characteristics deterioration due to different conditions, so we need to pay attention to it when we use it. When welding twice, it should be carried out after the first welding part is restored to normal temperature, otherwise continuous heating is easy to cause external deformation and terminal loosening, falling off or electrical characteristics reduction. When we operate the switch, we should be operated directly by people, do not use any mechanical detection function, otherwise when the switch operation is applied to the load, it is easy to cause the damage of the switch.
Tact switch is widely used in the market because of its small size, small resistance, good feeling when pressing, and complete types and sizes. Like some automobile industry, information industry. Appliance products, medical equipment, monitoring and other industries have been used.
