Explain the repair procedure of the membrane switch button


The following Jiahai Bodian explains the repair steps of the membrane switch button:

    1. First open the membrane switch panel. Then open the top layer of the membrane. Use a multimeter to find out the concatenated positions of each switch point and the circuit board to ensure that the converted switch connection point corresponds to the original one.


    2. Use a positioning cone on each plate of the base film to taper the plate wells on the metal plate. The perforation dimension is slightly larger than the actual size of the emblem type switch by the column. It is appropriate to ensure that the emblem type switch moves up and down in the hole without blocking. If the hole is too small, the elastic effect of the switch will be made to disable the switch.


    3. Compare the distance between each hole of the gold plate. Fix the emblem switch on the pad. Connect the appropriate connection point for each switch and connect the cable. According to the practice space 2 between the metal plate and the display plate, the corresponding plate edge is left to fix the switch plate. Since the new switch board is between the metal board and the indicator board, it is also necessary to make a hole corresponding to the sign board position 2 on the board to ensure that the board's light pipe passes through the board. The panel can see the visible signal. There must be a certain distance between the line and the two boards to prevent short circuits.


    4. The produced printed switch board is embedded in each hole corresponding to the switch and the metal plate, so that the top of the press column is parallel to the gold buttocks surface. If the board surface is too high, the outer layer After the panel membrane recovers, the switch can not be used. If it is too low, the switch cannot be operated when the switch is not pressed. The broken switch board' is embedded and flattened with a rubber pad, and the left glue is affixed to the metal plate. Afterwards, the outer protective film of the panel is recovered. The refitting process is completed after the modification of the switch board. The feel is very good. There is a clear shrapnel buzzing sound when pressed. Gives a very intuitive switch on and off feeling. Long service life, high reliability and convenient protection. If a switch breaks down during use, it can be directly judged by the click sound of the membrane switch button. Replace it.
