Embossing Back Light Membrane Switch With 3M 468 Adhesive and LFG


Backlit Membrane Switch


Many working environments and machines will be used in low light or dark conditions. So we will recommend illuminated membrane switches with internal lighting for backlighting in film. Choose EL film as the light guide plate, fiber optics, and the newer light guide film (LGF) structure. Niceone-tech recommends LGF, which uses side LEDs and light guide panels to make the product have a lower loss and longer life relative to the EL membrane switch.


LGF Membrane Switch: The LGF Technology


LGF stands for Light Guide Film that is responsible for directing light generated via right-angle LEDs or side-firing across areas where you need the backlit. It is basically a thin film backlighting technology that industries across the world have been using for backlit purposes.

The great thing about LGF technology is that it provides consistent backlighting regardless of the area shape. It also offers uniform lighting across multiple areas within the switch. It is possible to use multiple LG films within a certain application in order to offer discrete backlighting to different graphic features.


In order to achieve unique lighting effects, you can use different colored LEDs. On the overlay, you can associate different lighting colors with different printed graphics.


Advantages of LGF Lighting

LGF lights are available in almost any shape. Their versatility and flexibility make them the top choice for backlit switches.
LGF membrane switch is very useful for compact and thin devices.
It ensures minimal to almost no impact on the tactility of the switch buttons of the membrane.
With LGF switch, you can enjoy uniform lighting across one or more areas within a switch.
