Guang Dong Backlighting Membrane Switches from ChinaLuphiTouchPrinted ElectronicsQuality service

Backlighting Membrane Switches means that there is a light source from the backside to light the graphic overlay and provide the indication information to users or when the product used in the night or dark environment it can light the graphic and make the users or workers make buttons press operation correctly and avoid pressing wrong buttons.
There are several types of backlighting ways for the membrane switches. They are:
 LED backlighting membrane switches
 EL lamp backlighting membrane switches
 LGF(Light Guide Film) backlighting membrane switches
 Fiber backlighting membrane switches (seldom used nowadays due to their complex manufacturing process and very high cost. It has been replaced by EL lamp backlighting and LGF backlighting technology

For the LED backlighting keypads, the graphic overlay lighted by the backside LEDs assembled on the flex or rigid circuit layer. In this way, it is very simple and also economical.
But it couldn’t get an even lighting effect on the surface. For this backlighting method, the LEDs can be assembled under centered buttons also can be assembled beside the buttons or other areas. For the products need each button to be backlighted, usually design the LEDs under the center of the buttons, then use the center holed metal domes and print transparent color on the graphic overlay.

In this way, the center button will be much brighter than the sides of it. But this way is easy to achieve and also its cost is the lowest. This is suitable for those products with no very high requirement for the evenness of the backlighting.
