Easy operation: Membrane keypads are regarded as a user interface or human-machine interface, facilitates the inputting communications and commands, thus simplifying the operation of the electronic equipment.

Functions: Membrane keypads are electrical switches that can make the circuit turn on or off by changing the key pressure.

Composed of: Polyester, Lexan, Polycarbonate, adhesive, snap dome, connector, conductive inks, carbon ink, or copper flex circuit.

Features of Membrane Keypad

The reason why the membrane switch keypad is widely used is because of some very superior performances. It can fulfill various requirements of users, from industrial equipment to medical equipment.

Moisture-proof performance

Because the membrane switch keypad uses a good pressure-sensitive adhesive layer and the stable performance of Polyester, Lexan, Polycarbonate one of the materials together. Membrane switch keypad can be designed to meet NEMA 4 and IP 67, some products can even reach IP68.

Thin

First, it is not easy to be invaded by dust, and secondly, it reduces the space of the product.

Easy to clean

Membrane switch keypads are easier to clean the surface than other mechanical keyboards.

Cost-effective

Compared with touch keyboard and silicone rubber keyboard, membrane switch keypad cost will be more affordable.

Graphic interface

The topmost panel of the membrane switch keypad can be the most conventional screen printing or digital printing. Niceone-tech can design the product to achieve the best visual effect. At the same time display the company logo and key functions on the panel.

Protection by design

Through the design of membrane switch keypads can achieve antibacterial, anti-ultraviolet and other effects.

Why Choose Niceone-tech Membrane Keypads?

Niceone-tech can customize membrane switch keypad that are perfect and best suited to customer requirements according to customer needs. In order to let you know how the best and most suitable touch keypad membrane is produced, we must talk about its structure:

Overlay-Polyester

is usually the first choice for membrane switch keypad materials, because its life will be a little longer than Polycarbonate. If it is simply a panel instead of a membrane switch keypad, Lexan and Polyester are also good choices. The overlay is the most intuitive form of human-machine interface. Niceone-tech will screen print or digital print on the back of the material, and they can also be used in combination. Special requirements such as mirror silver effect are also feasible.

Overlay adhesive

As the first layer of adhesive paper under the panel, the Acrylic adhesive is usually used, generally the thickness is between 0.125-0.225mm. If it is LGF membrane switch keypad structure, the thickness sometimes reaches 0.64mm.

Top Circuit Layer (Dome retainer)

This layer usually has three functions: 1. As the Dome Retainer, it ensures that the Snap dome of the circuit layer will not form shrapnel movement due to triggering and closing, resulting in circuit failure and circuit wear. 2. Use 0.1-0.125mm Polyester printing conductive ink, carbon oil, and UV ink as the upper line. This layer structure can also be convex to make tactile feedback better. 3. Can be used as an ESD shielding layer.

Circuit Spacer (switch spacer)

Both upper and lower lines are printed with conductive ink, usually thicker tape is used to separate the upper and lower lines to avoid direct conduction of the membrane switch keypad. If the upper circuit is only used as a fixed layer, then the general thickness of the Overlay adhesive + Top Circuit Layer + Lower Circuit Layer should be greater than 0.4mm, otherwise, the panel will squeeze the shrapnel to make them feel worse. Unless the panel is convex, the four-layer structure is less than 0.4mm.

Lower Circuit Layer

The thickness of this layer circuit is usually 0.1-0.188mm. It can be printed with ink, carbon oil, and UV ink. LEDs can also be installed.  Some membrane switch keypads will choose the copper flex or Printing circuit Board as the circuit. Compared with Polyester, their performance will be more stable. More often applied to the medical and military industries. If it is copper flex or Printing circuit Board as a line, Niceone-tech can even install a variety of components on the line.

Rear Adhesive

There are many choices, but the most commonly used are 3M200MP series or 3M300LSE. According to the different products of membrane switch lamination, Niceone-tech will recommend 3M300LSE if it needs higher viscosity.

Rigid Support Layer

This layer structure is generally used as the last layer of the membrane switch keypad, which can make the structure of the membrane switch keypad component more complete. Usually, the choice of materials is AL, FR4, PC, or steel. If AL is selected, nuts or feet may sometimes be added to the back of the product.

If you are interested in Backlit Membrane Switch, please feel free to contact Niceone-tech, we will send samples as soon as possible.

Custom Membrane Keypad Design

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 keypad is in a more severe environment, we can even use hardened glass and stainless steel as the keypad material. It is very important to choose Overlay printing according to requirements.
