LGF is light guide film. LGF itself is not a light source. It couldn't produce the light. It still need the LEDs assembled on the circuit layer to produce the light source. But LGF can guide the light from the LEDs to top overlay evenly. For this backlighting keypad, it can save the LEDs quantity and it also can get a even backlighting effect with less LEDs. But by this way the difficulty is adjusting the refraction dots on the LGF layer. Adjust the direction of dots, density, position etc. And its tool fees is higher.  LGF Backlighting 0.5mm Pitch ZIF Connector Membrane Switch    4448 Product: Flat Tactile Buttons Waterproof Gasket Membrane Switch/Membrane Keypad/Membrane Keyboard; Waterproof Gasket: meet IP65, IP67, NEMA-4 standards; Application: Industrial Machine, Equipment; Tactile: flat buttons with tactile metal domes; Connector: 1.0mm pitch ZIF; Overlay: soft gray color silicone rubber; No LEDs; Rear Adhesive: 3M467MP; Circuit: silver printed PET circuit, 0.125mm thick;     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.
