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.


Membrane switch with LGF :

1.LGF is a thinner construction, without limited to devices thickness.
2.LGF has a limited impact on the tactile feel of buttons.
3.LGF can provide even backlight across larger and small areas.
4.Reliability and long lifetime, Low-Cost
Efficient power consumption and operating on lower voltage
5.Colors: White, Blue, Red, Green is a common choice.
