Being a cost-effective backlit option, LGF membrane switch is fairly common among a number of industries. For instance, it is perfect for designs that need backlit tactile keys. With the LGF membrane switch, you can either light all the keys are the same time or you can brighten them up individually.
This majorly depends upon the requirement of your product. It is possible to backlit big areas using multiple colors. Thus, making this an amazing technology even for status indicators including the sensors and the batteries, etc.
Below are some other applications that are well suited for LGF technology.
