Rubber Keypads

Because it has good insulation, heat resistance, high mechanical strength, transparency, and air tightness. Especially, it has flexural resistance and high elasticity is the ideal material of making a custom membrane keypad. The main function of the graphic adhesive is to closely connect the membrane overlay with the upper circuit layer. In general, this layer requires a thickness of between 0.05 and 0.15 MM. In the production, the switch manufacturer always uses a special membrane switch double-sided tape. However, some membrane switches are required to be waterproof and resistant to high temperatures.

Size, design and colour can be designed individually by you for all our membrane keypads. For some applications, the use of a keypad in combination with a front panel or a PCB offers definite advantages. In addition, front panels can also be fitted with simple front membranes and short-stroke keys. A custom graphic overlay / front fascia makes a powerful first impression of your company and your equipment. The graphic overlay is the first thing users see when they interact with your equipment. We can produce custom graphic overlays in customize size & shapes. We used high quality standard raw material like LEXAN PC film, Autotype Coated Polyester films & wide range of 3M adhesive. For machine-actuated applications, a “non-tactile membrane switch” may be a more economical solution. Tougher and completely sheltered from the outside environment, non-tactile membrane switches are rated for three times as many actuations as a tactile membrane switch.

Membrane Switch factory

Although membrane switches have been around for many years, they have proven to be very versatile and easily adaptable to new technology. As a membrane switch and keypad manufacturer, Quad Industries offers a wide range of modern features. Very thin and light can be assembled on many different materials surface, like plastic, metal, rubber etc. Waterproof and anti-UV for outdoor application, and also can use antifungal material for medical special application. Multicolored can be silk screen printed or digital printed graphic,Can be friendly interface and also can be designed backlit to convenient of the night or dark environment using. Membrane Switch keypad is an interface between man & machine, also called as User Interface or Human Machine Interface. A membrane switch is a simple electro mechanical device used to direct the flow of low voltage, low current electricity through an electrical circuit for turning a circuit on and off. A membrane switch contains a circuit, printed on special coated polyester films or used glass epoxy printed circuit board . We can provide durable and high-quality overlays to complete the branding and improve the quality of your product. We can provide embossing and windows, using the strongest 3M adhesive to ensure the longevity of your overlay.

Even better, they work seamlessly with other Hoffmann + Krippner products, including touchscreens and input devices. With our partners OKW and TES-Frontdesign, we can also incorporate an extensive portfolio of beautifully-designed, cost-effective enclosures – including stainless steel or aluminum. Ltd. is a prominent name in the field of membrane keypads, flexible membrane keyboards and polycarbonate stickers. As a leading membrane keypads manufacturer, supplier and exporter, we meet exact technical and design requirements of our customers. We serve the needs of many sectors like instrumentation, medical, security and aviation etc. Established in 1990, we are able to provide a perfect solution, giving total freedom in design, finish and quality. But on the other hand, there are also some potential disadvantages associated with membrane keypads. Unlike traditional mechanical keypads, membrane keypads have little-to-no tactile feedback. The good news, however, is that some membrane keypads are now being designed with tactile feedback mechanisms, such as vibration.

Flexible circuits allow a product form which is not possible with rigid PCB. Modern PC keyboards are essentially a membrane keyboard mechanism covered with an array of dome switches which give positive tactile feedback. Membrane keyboards work by electrical contact between the keyboard surface and the underlying circuits when keytop areas are pressed. These models were used with some early 1980s home computers, enjoying wide adoption in consumer electronics devices. The keyboards are quite inexpensive to mass-produce, and are more resistant against dirt and liquids than most other keyboards. However, due to a low or non-existent tactile feedback, most people have difficulty typing with them, especially when larger numbers of characters are being typed. Chiclet keyboards were a slight improvement, at least allowing individual keys to be felt to some extent. Under the leadership of experienced workers, we have experienced 3 years rapid development. Till now, we have been a professional membrane switch manufacturer. Always, we continuously learn advanced management experience in the industry.

The interacting layers are sealed together with adhesive to create a self-contained, low-voltage circuit in a tiny package. A membrane keypad can be combined with adjacent components and developed as a single operating unit. Electroluminescent lamps consist of foils with partially screen printed phosphor that glows when power is connected. For panels 1–3 mm in thickness, the technology can be used to highlight complex patterns that need to be visible in low light. For automatic adjustment between day and night lighting, photodiodes can be integrated directly into the membrane keypads. The special focus on materials means that a membrane keypads has a relatively long life with more than 10 million activations. When microorganisms encounter the surface of your user interface, their cell walls are penetrated by the protective agents within the membrane. Cell functions are interrupted, which prevents further growth and cell reproduction.

Keeping the track of latest development in this domain, we provide clients with Flexible Membrane Keyboard. Dyna-Graphics’ innovative “K-Motion” membrane switch technology is a cost-effective solution for a broad range of applications. Our K-Motion membrane switches are engineered to meet our customers’ most demanding requirements. We have extensive experience and expertise in the design, engineering, and manufacture of advanced membrane switch and HMI technology. Our innovative products—from touchscreen terminals to PCB assemblies to custom membrane switch panels—have helped make us an industry leader. Programmers once used to a mechanical keyboard, would not prefer membrane over mechanical keyboards. The typing experience offered by the mechanical keyboards is perhaps one of the prime reasons that should make it a great experience in programming as well. However, the right choice of the mechanical keyboard for programming would be dependent on the switch you choose.

Screen printing beautiful patterns and texts on the raw material, then the graphic overlay is finished. Usually, In general, the membrane switch manufacturer uses PET, PC or other colorless transparent sheets, which thickness is less than 0.25mm. As we all know, the main function of graphic overlay is to play the role of mark and button. It always acts as a touch screen not only in membrane switch keyboards but also membrane switch panels. Therefore, the material should have features of high transparency, high ink adhesion, high elasticity, and high toughness. Of course, according to the needs of customers and application scenarios, we HuaiSong Industrial can change the material to engineer and manufacture cost effective products.

Assemble the membrane overlay with the die cut semi-finished product. During the assembly process, we must ensure that there is no misalignment between each layer. 70% of the company’s customers come from the United States, Australia, Austria, the United Kingdom, Germany, Italy, Belgium, Sweden, South Africa, Japan and other countries and regions. We are familiar with the requirements and business processes of foreign customers. On this basis, we have established a complete set of business development, engineering R&D, design, production and quality control processes within the company. This slim, 16-button keypad provides a useful human interface component for microcontroller projects. It is well-supported for use with the Propeller microcontroller by BlocklyProp blocks and projects, as well as a C library and tutorial; see the links under Additional Resources. These membrane keypads work well for adding key input for a project.
