Membrane switch in accordance with the structure can be classified as several
1) Flat touchless type:
Long service life, but no touch;
2) film convex touch type:
Have a good touch, but the service life is relatively short;
3) convex border type without touch:
Beautiful appearance, a strong sense of three-dimensional, but no touch;
4) convex border type touch type:
Beautiful appearance, a strong sense of three-dimensional, and touch;
5) Panel hit convex touch type:
(A) type: improper design, prone to two phenomena, but the surface is damaged, electrical performance also exists;
(B) Type: There are no two phenomena, and the structure of the floor less, more economical, if the panel is damaged, the electrical performance will not exist;
6) metal shrapnel type:
(A) type: the most basic and most commonly used structure. Shrapnel both play the role of touch and play the role of the line;
(B) Type: The structure is complex, it is used in the occasions that the shrapnel is more dense and jumper wire is not required. The shrapnel is put on the upper circuit, the conductive surface of the upper and lower circuits are upward, and the upper circuit is punched. When the structure is turned on, the four feet of the shrapnel are not in the same plane with the center point, and the situation of "two sections" appears. At the same time, the shrapnel is often in the anti-concave over the strong state, over time, the shrapnel will not rebound phenomenon, not recommended;
(C) Type: Shrapnel placed on the line, only play the role of touch, the conductive line on the line down, down the line conductive surface up, there are "two" situation is not recommended;
(D) type: Shrapnel placed in the next line, the upper and lower lines are all traces, shrapnel both from the role of touch and play the role of the upper and lower lines connected; for Shrapnel more dense and do not have to jump Line occasions, compared to (b) -type structure is simple. Design should pay attention to the line alignment to avoid the four legs shrapnel, in order to ensure not short-circuit.
7) luminous body type: be sure to open the bottom plastic mold;
(A) The LED line is the same as that of the lower line. The structure is simple. However, if the height of the selected LED lamp is high, the LED lamp will lift the panel. At this time, the LED window on the panel should be convex, or the thick adhesive layer The thickness of the LED thickness greater than the thickness;
(B) Different layers of LED circuit and lower circuit: The structure is complicated, but the LED window does not have to be convex, but the upper area of the LED lamp must be hollowed out to prevent the light from passing through the LED lamp hole. Note: At this time under the line routing LED lighting holes around the need to avoid routing.
This type of jumper can be avoided and the hole can be perforated so that the conductive surface can be down, the disadvantage of this structure is easy to break the line at the fold easily.
9) waterproof inside and outside the box:
The outer frame is a closed frame, without alignment, the inner frame plays a protective role to prevent moisture from entering the housing from the outlet groove.
