Back Light Membrane Switch with water-proof and LGF design
As we see the technology evolve, consumers across industries are
looking for thinner and advanced lighting solutions. They want the
backlighting membrane without all the additional hassle. Engineers
are working hard to come up with solutions that are as effective as
the LGF membrane switch.
After the visible shift towards the Human Machine Interface designs
incorporating backlighting systems require sophisticated and
advanced lighting techniques. Engineers are trying to design
technologies that could fill the purpose without compromising on
quality and are cost-effective.
At the moment, the best option we have when it comes to
backlighting membrane switches is the LGF. It is the perfect
solution for uniform lighting, backlight areas, nearness to backlit
areas, multiple colors, and low profile.
In this blog post, we will be focusing on the LFG technology and
along with other custom membrane switch backlighting options.
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.
