1. First untie the film switch panel. And then open the above layer of press film.
Use the universal meter to find out each fit switch point and the line board of the junction t. to ensure that the modified switch junction point corresponds to the original.
2. Tap the dish hole on the metal plate with a positioning cone at each switch point of the base film.
The perforated scale is slightly larger than the standard scale of the emblem type switch, which is slightly larger by the standard of the column. To ensure that the emblem type switch moves up and down the hole according to the pillar and is not blocked. If the hole is too small, the elastic effect of the switch will sound the switch to make the switch fail.
3. Compare the distance of each small hole of the gold moon plate. Fix the emblem switch in the print board. And follow the connector point corresponding to each switch. Together, set aside the corresponding Plate Edge according to the practice space bit 2 between the metal plate and the appearance plate.
Since the new switch board is between the metal plate and the indicator display plate. It is also necessary to have holes on the print plate corresponding to the indicator level 2 of the manifest plate. To ensure that the light-emitting tube of the manifest plate can see the signal from the panel through the printed plate. There must be a definite distance between the line and the two plates to prevent short circuits.
4. The well-made printed switch board. Embedded in each small hole corresponding to the metal plate by each switch. Make the top of the column parallel to the gold fart plate face. If the outer plate surface is too high, the outer plane film will press the switch after recovery can not be applied. If it is too low. The switch is not in place when pressing with your hands. The broken switch board 'embedded after using rubber pad flat and reused, left glue stick on the metal plate. And then the panel outer protective film recovery. Bit after the modification process J modified switch board, the operation feel is very good. Long life- - High reliability - Protection convenience . . . if a switch is broken in use. It can be judged directly by the sound of shrapnel on the film switch button.
