By this way, it is very simple and also economical. But it couldn't get a even lighting effect on surface. For this backlighting method, the LEDs can be assembled under centered buttons also can be assembled beside of the buttons or other areas. For the products need each button be backlighted, usually design the LEDs under the center of the buttons, then use the center holed metal domes and print transparent color on the graphic overlay. By this way the center button will be much brighter than sides of it. But this way is easy to achieve and also its cost is the lowest. This is suitable for those products no very high requirement for the evenness of the backlighting.       Membrane Switches Design Factors  To make a quotation of the membrane switch need the following information: 1) Vectograph drawing, like CorelDraw, Ai, CAD drawing; 2) If no drawing, then we need know the following information:     2.1) How many colors on the graphic overlay layer?     2.2) How many buttons? Are the buttons need embossing or not? Need metal domes or not?     2.3) How many LEDs on the circuit?     2.4) Product outshape size?     2.5) Tail(circuit cable) lenth?     2.6) What kind of connector do you want? Female, male or ZIF? If need female and male connector, how many PINs? 3) If have an original sample it also will be good. We can copy the sample to design the engineering artwork drawings. As to the material and components that you are not familiared with, it doesn't matter, we can suggest the proper material as per our experiences.
