A touch switch is a miniature button switch that is widely used in digital professions, such as remote controls, floor to ceiling air conditioning panel buttons, power and volume buttons on mobile phones, all of which are touch switches. Especially in the mobile phone profession, almost every mobile phone has a touch switch.

Touch switches are also commonly used on air conditioning panels in hotels, hospitals, and other places, as well as control panels for rice cookers. Because touch switches have a wide range of applications, there are also some key considerations to consider during use:

During the entire application process, please design the switch according to the actual vertical operation orientation of the plunger. However, relying solely on one side of the plunger or the angled orifice plate may lead to a decrease in durability.

2. Especially during lateral pressure overload maintenance, the riveted parts will be damaged, which is the key cause of switch cracking. So when installing and operating, it is necessary to be careful not to exceed the overload maintenance during additional overload maintenance.

3. The application of a tactile switch relies on the movement of the button to make the contact or conductive rubber block contact the welding plate, and then establish a path. However, a contact switch is also known as a key switch. In order to meet the requirements of completing the homework, the switch is used to close the pressure switch function. When the pressure is relieved, the switch will disconnect. Therefore, the internal structure of the switch is completed by changing the force applied to the metal spring.

4. After lightly touching the switch and welding twice, the welding area should be restored to its original temperature before actual operation. If continuously heated, it may cause external deformation, causing the terminals to loosen, detach, and reduce electrical characteristics.

5. Because the operating force of the tactile switch is related to the condition of the chip. The starting force is directly proportional to the tightening distance. When the tightening amount reaches 5% -70%, the working force will suddenly decrease, accompanied by a "ticking" sound. There are generally two types of structures for guiding turtle rubber switches, and the operating force curve changes greatly with the shape of the rubber block.

6. Do not apply strong repetition of actual operations again. When the plunger is subjected to greater pressure, the excessive load may cause deformation of the circular plate projectile, resulting in poor projectile performance.

7. When welding the switch terminal with a light touch, if a load is applied to the terminal, the switch terminal may loosen due to different working conditions, and there may be deformation and deterioration of electrical characteristics. Please pay more attention throughout the application process.
