LGF is a thin plate that for help the side-firing LEDs illumination the switch. The LGF switch is like a mobile phone, the mobile phone screen can be lighting the whole screen, the LGF switch can be lighting the text/patterns that you want to. Adding the backlighting design to the switch make it easier for users to interact with the membrane switch. It help the membrane design to be more advance、multifunction and beautiful, the users is more like a such kind control switch.
There are several backlighting options with our switch design, the popular choice include: Light Guide Film(LGF), Electroluminescent(EL) lighting, Luminous powder lighting, or Fiber optic lighting. We can check your request and give you the best suggestion.
Our standard LGF switch design use the side-firing LEDs that apply to the printing polyester circuits, or the copper flexible circuits, or the PCBs, then add the LGF plate upon the key buttons. The such design is very easy for the manufactures that assembly the parts to their machine, You don’t need to design your PCBs to be very complex/Add the control ICs, and You also don’t need to design the very high power that work for the such switch.
With the LGF switch controller design, this one of the best and economy way that design your machine superior!
