Keyflex is a reputable supplier and membrane keypad manufacturer, specializing in providing comprehensive solutions for custom labels, graphic overlays and switching applications that perfectly complement your equipment design while enhancing its functionality. As a leading membrane keypad manufacturer, we understand the demands of the industry and prioritize using high-quality materials such as polyester, polycarbonate, and polyurethane in the production of our membrane switches and graphic overlays. We carefully select these materials to ensure optimal performance and durability, meeting the rigorous requirements of various applications.
At our facility, we offer a complete range of design and supply services, including meticulous artwork and mechanical drawings for all our decal and membrane products. Our experienced team collaborates closely with clients to understand their specific needs and provide tailored solutions that meet their unique requirements. In situations where time is of the essence, we offer the added convenience of creating prototypes using cutting-edge digital output and laser cutting technologies. This approach eliminates the need for costly production tooling until the final design has been confirmed, saving valuable time and resources.
As a supplier of keypads, Keyflex membrane switches are renowned for their versatility and performance. These switches not only provide a reliable interface for users but can also incorporate tactile switches that offer tactile feedback, thereby enhancing the overall user experience. Additionally, our keypads can be equipped with LEDs, enabling intuitive visual feedback and enhancing visibility in various environments.
To cater to different installation requirements, we supply Keyflex membrane keypads and switches with terminating connectors or ZIF contacts, facilitating easy integration into your equipment or system. We understand the importance of visibility in certain applications, which is why our switches can be designed with clear windows tailored specifically for liquid crystal displays (LCDs). Furthermore, we offer electro-luminescent backlighting options, ensuring that your membrane panel or front panel decal remains visible even in low-light conditions.
In our commitment to continuous innovation, we have developed a cutting-edge integrated LED light guide film. This groundbreaking technology allows us to provide a thin film integrated backlight solution for graphics incorporated into your membrane panel or front panel decal. This innovative approach ensures seamless integration of the backlighting into the panel, maintaining a uniform and visually appealing appearance. Moreover, this new development enables us to achieve a similar thickness to standard membrane switch panels, ensuring ease of integration into your equipment design.
As a distinguished membrane keypad supplier, we are dedicated to delivering exceptional products that meet the highest standards of quality and functionality. With our Keyflex Membrane switches and graphic overlays, you can expect superior performance, durability, and design flexibility. Whether you require a customized solution or a large-scale production order, our dedicated team of experts is ready to assist you throughout the entire process, from design to delivery. Discover the difference our expertise can make and explore the endless possibilities that Keyflex Membrane switches and graphic overlays offer for your equipment design needs.

LGF (Light guide film) Membrane Keypads with integrated backlight
Backlit membrane switches
The light guide film (LGF) brings integrated LED backlighting to membrane switches and front panel decals allowing text and full key illumination. Our LGF provides even light distribution across the keypad/decal front panel while keeping the thickness similar to standard membrane switch panels.
Outstanding Reliability for membrane switches
We test our membranes, materials and components for operational lifespan to give you peace of mind

Membrane design - Material characteristics
Circuit layers
There are two basic types of circuit layers that are used in membrane switch assemblies, PET and FPC. PET is a polyester where the circuit is laid out in silver ink and applied to the base material using a screen-printing process.
It is suitable for circuit pitches of 1mm and upwards.
FPC or flexible printed circuit
FPC is a polyimide (Kaptron) base with a copper etch for the circuit, similar to traditional PCB manufacture but in a much thinner format and allows for soldering of components and connectors.
It is best suited for circuit pitches under 1mm (eg 0.50mm)
Graphic Overlay materials
Graphic overlays for membrane switches are commonly made from polyester material. This choice of material is essential because it provides the necessary flexibility for seamless membrane switch operation, ensuring that the overlay does not fracture or break under pressure. In contrast, polycarbonate is often preferred as a base material for decals, overlays, and labels where movement is not a factor. However, when it comes to membrane switch applications, polycarbonate is not the ideal choice due to its limitations.
Polyester films offer various advantages for graphic overlays, including the ability to have a gloss or textured hardcoat finish directly embedded onto the film itself. This feature enhances the aesthetic appeal of the overlays while also adding a layer of protection. Additionally, it is possible to incorporate texturing and gloss finish areas using UV silk screening techniques applied to the base polyester.
When considering outdoor applications, it is crucial to prioritize UV stability to ensure longevity and durability. In this regard, Autotex XE stands out as a recommended option due to its excellent UV stability properties. By utilizing Autotex XE for outdoor graphic overlays, you can be confident that the overlays will resist the damaging effects of prolonged sun exposure, maintaining their vibrant appearance and functionality over time.
For medical applications, a specialized option known as Autotex AM is available. Autotex AM offers an additional layer of protection by incorporating an embedded antimicrobial agent within the surface coating of the overlay. This feature helps inhibit the growth and spread of harmful microorganisms, making it an ideal choice for medical environments where cleanliness and hygiene are of utmost importance.
In conclusion, the choice of materials for graphic overlays is crucial in ensuring optimal performance and longevity. Polyester films provide the necessary flexibility, while options such as Autotex XE and Autotex AM offer additional benefits such as UV stability and antimicrobial properties, respectively. By considering these technical details and selecting the most suitable material for specific applications, manufacturers can create high-quality graphic overlays that meet the diverse needs of their customers.
