BACKLIGHTING YOUR SILICONE RUBBER KEYPAD APPLICATION

If you would like to backlight your application, the construction would incorporate either light guides or LEDs for uniform lighting.  Other options for backlighting are fiber optic backlighting and EL backlighting.  Depending on the requirements of your application such as thickness preference, shape, environmental exposure, and other unique specifications, the backlighting options would vary and be selected specifically to fit the function of your device.  Using the latest LED powered lighting can reduce cost and reduce power used by a device.  Since many devices today are portable, this backlighting solution is more relevant than ever.

A variety of applications that use backlighting solutions are: remote controls, laboratory equipment, airplane dashboards, medical devices in dimly lit operating rooms, consumer appliances, such as coffee makers and microwaves, laptop keyboards, and many other applications that we all come in contact with daily or sporadically.

We have various backlighting samples that you can evaluate and consider for your application.  Please feel free to submit a sample request  and we’ll send you a variety of useful samples and tools you can experiment with for your application.
