How to identify the quality of the tact switch

The quality of tact switch products is reflected in: 1. The accuracy of the parts processing technology and the quality of the electroplating layer; 2. On-resistance size. 3. The appropriateness of the hand feel. 4. Whether the service life meets the design requirements. 5. Whether the protection level meets the requirements of the use environment, etc. Parts process: The pin base material of the tact switch is brass or phosphor bronze. After stamping, electroplating must be carried out to avoid easy oxidation and reduce circuit resistance. In this case, stamping and plating will be directly related to the accuracy and good coating of the terminal. Therefore, high-quality tact switches strictly control the manufacture of these two processes. Conductive Impedance: The key influencing factor is the structure and coating of the contact point. The function of the tact switch is to touch the contacts and shrapnel, so the conductivity of the contact point coating is directly related to the conductivity. Second, the bigger the contact surface, the better. The contact surface is determined by the structure, so the product structure design is also very important. Action life. Hand feel: The life and touch of the tact switch is made of the key component reed. The structure and material of the basic suspension machine are determined, so the material selection and structural design must have professional knowledge and scientific repeated verification and improvement in order to produce Good and practical product. Assembly process: The tact switch is installed in the environment of the assembly workshop. The manufacturing process and control are extremely important. The requirements of the assembly workshop must reach the 100,000-level purification workshop. Precise assembly processes are planned from the beginning of product design. The modern manufacturing industry has basically completed the automated production process. Through systematic quality control, the output of high-quality products is guaranteed. Quality inspection: Factory inspection methods and items are an important link for the quality assurance and reliable performance of tact switches, such as the inspection of items such as appearance, touch, continuity, resistance, etc., to directly control and ensure yield, and supervise inspection capabilities.
