Backlit Membrane Switch

Many working environments and machines will be used in low light or dark conditions. So we will recommend illuminated membrane switch with internal lighting for backlighting in film. Choose EL film as the light guide plate, fiber optics, and the newer light guide film (LGF) structure. Niceone-tech recommends LGF, which uses side LEDs and light guide panels to make the product have a lower loss and longer life relative to the EL membrane switch. 

The thickness of the LGF membrane switch provided by Niceone-tech can even be 0.8mm. 
The brightness of buttons and logos is not only uniform and long-lasting but more importantly, we can also make them illuminate each button individually. 
Sometimes you can also use two-color or RGB three-color lights to enter one step makes the product more beautiful.

Three Other Types of Illuminating Membrane Switches Below

Electroluminescent (EL)

EL backlight is driven by high frequency and low power. EL is very thin, it is a substitute for traditional lighting technology, and is widely used in various electronic accessories. The life of EL backlight products mainly depends on the driving voltage, frequency, temperature and humidity. But most EL membrane switches can reach a life of 4000 hours or more. The brightness of the EL membrane switch (to change into Backlit Membrane Switch) will attenuate linearly from the initial power-on. This is also an unavoidable disadvantage relative to other backlight membrane switch panels.

The EL backlit membrane switch provided by Niceone-tech will not cause heat, electricity and EMI problems. Mainly EL is more often a "cold" lighting medium.

Fiber Optics

Fiber optic membrane switches are also a good choice for backlighting. The optical fiber material is very thin and can be used as a fixed layer of the membrane switch. At the same time, tactile feedback is better without adding a touch point. Life expectancy is up to 50,000 to 100,000 hours. The main light source is from LEDs

Through the optical fiber transmission in the membrane switch needs to light up. And can be larger than the surface-mounted LED backlight area. Click Fiber Optics membrane switch (to change into Backlit Membrane Switch) for more information.

LEDs

A common Light Emitting Diodes membrane switch (to change into Backlit Membrane Switch) with relatively low cost. Since LED backlighting techniques for membrane switch cannot meet the lighting of a large area, it is mostly used for indication purposes. It is a relatively old technology. But the service life is long and deep customers love it.

Applications of Backlit Membrane Switches
Niceone-tech's custom-designed membrane switches and membrane switch keypads. Membrane switches are used in many industries. Niceone-tech summarizes several best membrane switch industries:

Medical Equipment and laboratories are the major markets. Niceone-tech provides customized membrane switches with complex requirements for many European and American manufacturers. In the medical environment, based on the standard membrane keypad, the materials sometimes have antibacterial effects and easy cleaning characteristics. At the same time Niceone-tech applies backlit and glue technology to the membrane switch. It can even be produced using digital printing.

Industrial Controls: Because industrial equipment is more demanding moisture resistance and UV resistance, so the product's waterproof requirements and UV resistance performance requirements are relatively high. The choice of materials can refer to the membrane switch design guide (to change into go This page), I believe that the materials compiled by Niceone-tech can help you.

Health & Fitness Equipment: Because it is often corroded by sweat, salt and moisture, the material must be resistant to corrosion. Membrane switches are often used in treadmills. Using membrane switches to optimize performance and control is very important for fitness personnel

What industry are you in?


Normal Structure of Backlit Membrane Switch：
Graphic overlays digitally and/or screen printed on the backside. The effect can be customized according to your requirements including glass, metal, wood, and stone. If the panel is in a more severe environment, we can even use hardened glass and stainless steel as the panel material. It is very important to choose Overlay printing according to requirements.

The window needs raw materials to be transparent, frosted, transparent, or colored. The window of the membrane switch is different, and the choice of materials is also very different. When the window is large, and it is required to clearly see the bottom LCD or touch screen. EBG series is a good choice, the material is scratch resistant. If it is just a panel, then PC or Lexan overlay is also feasible

Selective textures and UV hard-coat surface finishes

Tactile or nontactile, snap dome, or nonsnap dome.

Pillow rim-embossed membrane switch panels

Optically clear adhesive (OCA)，Liquid Optically Clear Adhesive，Air Gap(to change into Optical Bonding in Membrane Switches and User Interfaces)

EMI/RFI shielding

Rigid support backers such as aluminum and FR4 with PEM mounting fasteners

Standard connectors such as CJT, Nicomatic and Molex, etc
