Membrane switches china are simply a part of electronic equipment, and are often regarded as user interfaces or human-machine interfaces, making it easier for operators to input communications and commands to operate electronic equipment, making users more convenient. Membrane switch can also be called membrane panel. Membrane keypad or membrane keyboard is an electrical switch that can make the circuit turn on or off by changing the key pressure. Generally composed of Polyester, Lexan, Polycarbonate, adhesive, snap dome, connector, conductive inks, carbon ink or copper flex circuit.

What can Niceone-tech could do?

Niceone-tech customized microwave membrane switch for different customers are widely used in various industries, empower exceptional product design for other man-machine interface solutions.

Membrane switch constantly updates and upgrades its technology, and its durability is gradually improved. Because of its superior performance and affordable price. As a reliable human-machine interface, it is increasingly favored by home, office and industrial applications.

Niceone-tech strictly customizes products in accordance with ISO9001-2015, and invests a lot of money every year to develop the technology of the membrane switch to improve the added value of products such as performance, life and function. Our membrane switches are exported in large quantities to European and American countries with stable quality and affordable prices. Niceone-tech understands the standards of European and American countries, so the products are always able to meet and exceed customer expectations.

What are the functions and advantages of membrane switches?

The reason why the membrane switch 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 uses a good pressure-sensitive adhesive layer and the stable performance of Polyester, Lexan, Polycarbonate one of the materials together. Membrane switch 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 switches are easier to clean the surface than other mechanical keyboards.

Cost-effective: Compared with touch keyboard and silicone rubber keyboard, membrane switch cost will be more affordable.

Graphic interface: The topmost panel of the membrane switch 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 switches can achieve antibacterial, anti-ultraviolet and other effects.

Why use the membrane keypad made by Niceone-tech?

Niceone-tech can customize products 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 membrane switch is produced, we must talk about its structure:

1. Overlay-Polyester is usually the first choice for membrane switch panel materials, because its life will be a little longer than Polycarbonate. If it is simply a panel instead of a membrane switch, Lexan and Polyester are also good choices. 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.

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

3. 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 ESD shielding layer.

4. 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. If the upper circuit is only used as a fixed layer, then the general thickness of Overlay adhesive + Top Circuit Layer + Lower Circuit Layer should be greater than 0.4mm, otherwise the panel will squeeze the shrapnel to make the feel worse. Unless the panel is convex, the four-layer structure is less than 0.4mm.

5. 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 panels will choose 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.

6. 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.

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

What special features can Niceone-tech membrane switches provide?

Backlighting Membrane Switch with Side-LEDs

Many working environments and machines will be used in low light or dark conditions. At this time, the customer asked us if we could solve this problem. At this time we will recommend the use of membrane switches with internal lighting. 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 lower loss and longer life relative to EL membrane switch. Also available in different colors.

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.

*If the customer wants the product to be more novel and beautiful, then we can sometimes use Epoxy in combination with the keys. Makes it an Epoxy LGF membrane switch

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

There are three other types of illuminating membrane switches below.

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 for more information.
