What are the main performance characteristics of the panel key molding structure of the membrane switch and the maintenance methods of the membrane switch?
The panel button forming knot of the membrane switch is formed by punching and shearing a piece of membrane switch sheet into connected sheet buttons arranged with hollow lines that have proper press recovery elasticity. The hollow line cuts adjacent sheet buttons that cannot be linked when pressed Arrangement, the surface of each sheet key is directly hollowed out with words, numbers or symbols, and then a piece of light-transmitting film is bonded to the bottom surface of each key.
1. The main performance characteristics of the panel button forming structure of the membrane switch:
1. The surface of each sheet key is directly hollowed out with numbers, characters or symbols, and then a piece of light-transmitting film is bonded to the bottom surface of each piece of key. Numbers and symbols.
2. A membrane switch panel button forming structure, characterized in that a sheet of membrane switch is formed by punching and shearing into a sheet button shape that is divided and arranged with hollow lines and has proper press recovery elasticity, and the hollow lines cut each phase The arrangement of the adjacent slice keys cannot be linked when pressed.
2. What are the methods of repairing the membrane switch:
1. First disassemble the membrane switch, and then lift the upper layer of the key film, and use a multimeter to find out the connection position between each key switch point and the circuit board, so as to confirm that the modified switch connection point corresponds to the original one.
2. At each switch point of the lower film, use a positioning cone to tap a plate hole on the metal plate. The size of the perforated hole is slightly larger than the actual size of the badge-type switch press pin, so as to determine the position of the badge-type switch press pin. It is advisable that the up and down movement in the hole is not hindered. If the hole is too small, the elastic action of the switch will be affected and the switch will fail.
3. According to the spacing of each small hole on the golden moon board, fix the emblem switch on the printed board, and connect the connecting wire according to the connection point corresponding to each switch. At the same time, according to the actual space position 2 between the metal plate and the display panel, reserve the corresponding printing plate edge to fix the switch plate. Because the new switch board is between the metal plate and the indicator light display board, a hole corresponding to the indicator position 2 of the display board is also required to be drilled on the printed board to ensure that the light-emitting tube of the display board passes through the printed board from the The display signal can be seen on the panel, and there must be a certain distance between the line and the two boards to prevent short circuits.
4. Embed the prepared printed switch board in the small hole corresponding to each button switch and the metal plate, so that the front end of the button column is parallel to the gold fart board surface. If it exceeds the board surface too high, the outer layer After the panel film is restored, it will press the switch and cannot be used. If it is too low, the switch will not be in place and cannot work when pressed by hand. After the broken switch board is embedded, use it again with a rubber pad. The left glue is pasted on the metal plate, and finally the outer protective film of the panel is restored to its original state. After the refitting process is completed, the refitted switch board is operated. It feels good in the hand, and there is a clear sound of shrapnel when pressing the button, which gives people an intuitive feeling of switching on and off. The service life is good, the performance is good, and the maintenance is convenient. If a switch is broken during use, it can be directly judged by the sound of the shrapnel when pressing the button, and it can be replaced.
