What are the maintenance methods of the film switch?

The panel utility model of the film switch relates to a key forming structure of the film panel, so that it can be combined with a corresponding control panel, and the pressing convex body arranged in the center of the bottom surface of the transparent rubber film is relative to the touch switch arranged in the control panel, and the combination for pressing and touching control is composed. It CAN SAVE a LOT OF manufacturing COST AND THE MAN-HOUR COST OF EACH INSTALLATION AND COMBINATION BY USING THE PANEL MADE OF one STAMPING INSTEAD OF EACH KEY. It has multiple economic benefits.

Membrane switch panel key forming junction is a membrane switch chip to hollow out for punching and shearing molding line segmentation he connected with the proper press return elasticity sheet button, hollow out line cutting each adjacent flake not moving and the arrangement of buttons to press, the sheet button directly on the surface of hollow out words, Numbers, or symbols at the bottom, bonding each button again pervious to light film.

A film switch panel key forming structure of the main performance characteristics

1. The surface of each sheet key is directly hollowed out with numbers, words or symbols, and then a transparent rubber film is bonded to the bottom of each sheet key. The hollowed surface of the sheet key is not afraid of water and can show words, numbers and symbols through the transparent rubber film.

2. A panel key forming structure of a film switch is characterized by a thin film switch sheet formed by punching and shearing, which is segmented by hollow lines to arrange the shape of sheet keys with appropriate pressure and resilience, and the adjacent sheet keys cut by hollow lines are arranged in such a way that they cannot be connected when pressed.

Two, what are the methods of maintaining the film switch:

1. At first, disassemble the membrane switch, then uncover the upper layer of healthy film, and use a multimeter to find out the connection position between each healthy switch point and the circuit board, so as to determine that the modified switch connection point corresponds to the original one.

2, in the lower film on each switch point with a positioning cone on the metal plate cone good position dish hole, the perforation size than the seal type switch according to the actual size of the column is slightly larger, to determine the seal type switch according to the column in the hole movement up and down is not blocked, if the hole is too small will be shaped ring switch elastic effect switch failure.

3. According to the spacing of each hole of the gold plate, fix the emblem switch on the printing plate, and connect the connecting line according to the corresponding connection point of each switch. At the same time according to the actual space between the metal plate and the display plate 2 set aside 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, the printed board also needs to be made with a hole corresponding to the indicator light position 2 of the display board, to ensure that the light tube of the display board through the printed board can see the display signal from the panel, and there should be a certain distance between the line and the two boards to prevent short circuit.

The printed switch plate is embedded in the hole corresponding to each press switch and the metal plate, so that the front end of the press column is parallel to the gold butt plate surface. If it is too high beyond the plate surface, the outer panel film will press the switch after recovery and cannot be used. If it is too low, the switch will not work if it is not in place when pressed by hand. The broken switch plate is embedded and then used like a rubber pad. The left rubber is pasted on the metal plate, and the outer protective film of the panel is restored to its original state. After the modification process, the modified switch plate has a good operating feel, and there is a clear shrapnel sound when pressing the button, which gives people an intuitive feeling of switching on and off. Good service life, good sex, easy maintenance, in use if a switch catch bad, can be directly judged by the shrapnel sound when the key, replace it.
