1. First disassemble the film panel and then uncover the upper layer of press button film. Use multimeter to find out the connection position t between each key switch point and circuit board, so as to ensure that the modified switch connection point corresponds to the original one.
2. At each switch point of the lower film, use the positioning cone to taper the good position dish hole on the metal plate. The perforated size is slightly larger than the actual size of the coat type switch according to the quilt column. It is advisable to ensure that the coat type switch moves up and down in the hole according to the healthy column.
3. Compare the spacing of each small hole of the gold moon plate. Fix the emblem switch on the printing plate and connect the connecting line according to the connecting point of each switch. At the same time, according to the actual space between the metal plate and the display plate, set aside the corresponding side of the play plate to fix the switch plate. Because the new switch plate is located between the metal plate and the indicator display plate, holes corresponding to the indicator position 2 of the display plate must also be marked on the printing plate to ensure that the light tube of the display plate passes through the printed plate and the display signal can be seen from the panel. At the same time, there should be a certain distance between the circuit and the two plates to prevent short circuit.
4. Insert the printed switch plate into the holes corresponding to the metal plate. Make the top of the press pillar parallel to the surface of the gold butt plate. After embedding the broken switch board, use it as a rubber pad before using it, and paste it on the metal plate after glue is dead. And then restore the outer protective film of the panel to its original state. Long service life, high reliability, easy maintenance, if a switch caught in use.
