To make connector pitch 0.5mm or less, we suggest adopt FPC circuit with ZIF type connector or PCB circuit with soldered FFC/ FMC cable. Membrane switch supports several kinds of media connector to meet your demands. A ZIF type ribbon cable is the most economic solution for connection purpose; print carbon on pin contacts will effectively prolong the durability of the cable. For a plug-in connection, we shall crimp metal pins, female contact or male tab, on cable end and protect the metal pin with plastic housing. Customer shall specify the dome height or stroke distance and actuation force wanted. The life time of a metal dome switch is at least 1 million click cycles, and metal dome made by specific manufacturer could be durable up to 5 million cycles. After checking the environment, the lamination process is carried out. The membrane switch is then placed in the appropriate position and a portion of it is laminated, then the remaining centrifugal paper is slowly removed.
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. Made of polyester or polycarbonate, it can be screen printed or digitally printed to your specifications to tell users how and where to press. The overlay typically will have letters, symbols, and icons printed on to indicate where to press. Embossed domes may be designed under the icons for a more intuitive button interface. Thirdly, the heat stabilized polyester has good elasticity and temperature resistance. But the surface of raw material is difficult to be processed into a matte texture, and it’s mostly transparent. At the same time, for most plastic inks, if use them to get polyester printed, it’s hard to get satisfactory affect. In general, graphic overlay manufacturers need to use special and exclusive inks.
Selective textures and scratch-resistant hard coat coatings can be added to the overlay surface to provide unique appearances and enhance functional performance. Tactile domes provide the functional actuation you need with physical feedback in a durable and reliable package.

A membrane switch is a user interface device that is made up of several layers and used as a switch to turn a device on or off. Polyester, polycarbonate and polyurethane typically make up the components of a membrane switch panel. Internally, the switching mechanisms are via metal domes or conductive shorting pads. Further enhancements include surface mount LEDs, water clear widows, dead fronts, back-lighting with optic fibre orelectroluminescenceand solid mounting plates. Terminations to the PCB can be via Berg connectors and Nicomatic connectors or designed to fit Ziff connectors. Membrane switches, also known as membrane panels or keypads, are electrical switches with a user interface to control equipment and machines. The top layer is typically the graphical interface, also known as a graphic overlay, which identifies the functions being controlled using icons or text. Dyna-graphics is a trusted waterproof membrane switch andrubber keypadmanufacturer.
It can meet the requirements of most membrane switch panels, and the high transmittance of PC can meet the requirements of LCD window. Single-sided membrane switches are often more susceptible to electrostatic discharge , as they are forced to push traces farther into the perimeter, increasing the risk of ESD escaping outside the edge of the circuit. As D/SPC allows for traces to be printed on both sides of the circuit substrate, enabling a wider outer perimeter between the traces and the switch edge, you may be able to avoid shielding all together. With D/SPC, you can also eliminate the need for a tab or slot that connects the shield to the ground, as the shield layer can be connected to the circuit through the use of a printed thru-hole. If your membrane switch will be exposed to excessive ESD or radio frequency interference , Reliaswitch can be designed with a carbon or silver shield for extra protection. In addition to thoroughly inspecting and 100% performance testing each product, we also provide value added assembly services. We can provide you with a fully assembled and turn-key solution for your user interface so it is ready to hit the assembly line and streamline your manufacturing process. We can source and assemble sheet metal, injection molded plastics, control boards, and displays to combine with our products to provide a complete solution. Many machines and work stations operate in low light conditions, which mandates internally illuminated membrane switches. An ingenious combination of side-LED and light diffusing panels improves upon electroluminescent film technology to offer extensive color options, low power consumption, flat design, and long lifespan.
A membrane switch offers numerous advantages over a tradition mechanical switch. Rigid Support Layer – This backmost layer offers support for free-standing membrane assemblies. A membrane keypad integrated into a larger product may not need this layer. If you need a membrane switch product quickly, count on the experts at Tekra to get it to you. If you have any questions when selecting the right product, contact us or check out the3M™ Converter Markets Selection Guidefor more product details. Understanding the difference between a membrane switch and a mechanical switch is actually quite simple, as the difference has more to do with the build and form of the switch rather than its functionality. When you consider it in terms of actual operation, both utilities essentially work the same.
Membrane switch panels are made of several layers of polyester printed and assembled together. They allow to create a custom human-machine interface at a reasonable price with low investment cost. This type of membrane switches is the most reliable and economical one. However, note that non-tactile membrane switches don’t give users direct feedback from the switch. You can address this problem by using a display change or LED indicator. Another advantage of non-tactile switches is that they allow to easily create custom shapes and sizes of the active keypad area. One of the best ways to enhance customer experiences with your products is to add simple backlighting solutions to your designs. Bulky, problematic systems with hundreds of fiber optics are now a thing of the past. Xymox backlighting kits help you save space with the LEDs and conductive screen printing all on one sheet of polyester.
Such multi-layered switches may include a type of ESD, EMI, or RFD shielding, as well as embedded components like LEDs, resistors, or light sensors. To make all of these work together, our experts use copper flex or PCBs to develop the circuit layer. The PCB Membrane Switch construction utilizes a printed circuit board which can serve a dual purpose in your membrane switch design. PCB Switches are typically more costly than Silver Flex membrane keypads, but can accommodate dense circuit patterns and more complex circuit patterns compared to Silver Flex membrane keypads. This switching technology combines the ability to accommodate the complex circuit patterns of a FR4 rigid printed circuit board with the flexibility of a membrane switch. Copper Flex keypads also have the advantage of being able to “hard” solder both active and passive components into the assembly, making it a good choice in high-vibration environments. Non-tactile membrane switches are typically used when low cost is the primary driver of design considerations. Although this type of membrane switch is rated for higher actuations, it lacks the physical “snap” feedback of a tactile membrane switch, requiring the incorporation of sound or visual cues to indicate activation. Providing a responsive and intuitive interface can help your product stand out.
In some cases, they even last three times as long as their tactile counterparts. Position the membrane switch at 30° & peel the rest of the adhesive liner. However, you can add a sound or light component to indicate their activation. Depending on your design, you might need to add an electronic shielding technique. Tactile feedback is the feeling users experience when they push a button. You can choose from different materials and sizes for your buttons, and these choices will require different actuation forces for activating the switch.
Compared to a traditional manual switch, membrane switches are thinner and have fewer limitations. Because of their greater design flexibility, membrane switches are excellent for creating user-friendly, modern-looking control panels. How to provide audible and tactile feedback – We can employ a physical contact in the form of a plated metal contact disc, commonly referred to as a dome.

Our success has been based on our understanding of the demands and nature of promotional and marketing deadlines. Classification of endocytic pathways has been a challenge ever since the discovery of clathrin-independent uptake processes. In this review, we have argued that a limited set of physical principles can be used to group biochemical machinery into functional modules. We anticipate that individual modules will be shared between different endocytic events, and that specificity within a given uptake process arises from defined cocktails of modules. Such classification of endocytic events would thus consist of a chain of defined module identity, rather than a reductionist limitation to one functional element. Biological membrane scission is another example for which the from-simple-to-complex paradigm appears to apply.

Since many devices today are portable, this backlighting solution is more relevant than ever. Plastic Injected molded cases have the advantage of a molded cavity to receive a membrane switch that allows the membrane to be flush with the case surface. The color and texture of the case can tie into the membrane switch and appear as one piece. This type of membrane switch panel is common in the medical industry where esthetics is of high importance. Parting lines, bosses, and injector pin marks should be avoided in any switch button locations to prevent switch actuation problems. We provide OEM/ODM service, custom membrane switches, a total solution from design, production, brand design, packing, marketing and the suggestion of distribution channel. Membrane switches are printed electronic circuits which are used to turn circuits on and off. Further, these circuits use conductive inks made of silver, granite, and copper. They are a part of various electrical devises and appliances and have double based touch-screens, push-buttons, toggle-rocker etc.
The PCB can also be used to for soldered components allowing the side opposite of the graphic layer to used for mounting displays, backlighting, or interface electronics. Keys can be made to provide either a tactile sensation or no sensation at all . Metal domes,formed polyester domes or elastomer snap can be used to provide a tactile response to the keys. Elastomer membrane switches can have a flex static layer or rigid static layer . The simplest elastomer membrane switch is made with two layers using a decorative elastomer internally tactile over a PCB. Moreover, manufacturers can use embossing together with non-tactile or tactile membrane switches. Note that pillow embossing doesn’t give the membrane switch a tactile response.
