Likewise, you can leave room for components on the membrane switch. In case, you involve the backlighting, you need to use different lighting blocking layers. Some of these layers include fiber optics, LEDs, Electroluminescent.

In order to control the direction of the light, you can print the layer behind the overlay. When you do this, it is bound to increase the opacity. To ensure the quality of the membrane switch, you need to focus on the material of overlays.
