ZIF connectors may have anywhere from 2 to 30 positions on a single row, and distances of between 1mm and 2.54 mm are available. Cubbison can offer aluminum, polycarbonate and acrylic material options for a rigid subpanel. It is usually advisable for the subpanel to be slightly smaller than the membrane switch. Conversely the holes and cutouts should be slightly larger than those on the membrane in order to conceal the sub panel. LED – Surface mount LED’s can be embedded into the membrane switch. LED’s are mounted onto the circuit layer using our pick and place unit. This is the least expensive backlighting option, and it is used primarily for indication and single point illumination.
LED Backlighting – Custom backlighting solutions for your product can include; led light guide films, EL Lamps, and fiber optics. While LED light guide films can provide the most even lighting options, each application has its advantages and we can help guide you to the best solution for your project. Membrane switches also offer a high level of protection against moisture and other liquids. Although they can be designed in different ways, most membrane switches feature a sealed top layer that’s made of silicone rubber or a similar soft and elastic material. The presence of this layer prevents moisture and liquids from reaching the underlying circuit.

The circuit layer is the next layer moving inward and resides between the spacer layers and the membrane switch rear adhesive. The circuit layers primary responsibility is to carry the switches electrical signals and provides the most critical functionality of the membrane switch.
Non-tactile switches also have the advantage of easily creating custom shapes and sizes of the active keypad areas. These types of connectors are considered to be more reliable against heavy shock and vibration. With a much larger connection, male, female, and solder connectors have pins crimped to the circuit and are available with many different housing features. Keep in mind that ZIF connections degrade with insertions, so the maximum number of insertions should not exceed 10 cycles. It’s also important to remember to take care when placing the tail die but in relation to the printed traces, since resistance in the circuit may increase in spacing of less than 1mm where the circuit traces are thinner. LUPHITOUCH’s inner testing room can do the salt spray test, waterproof test, buttons life test, temperature and humidity test, etc to assure our manufactured keypads quality.
After the customer requirements form is completed, our design exerts can get to work. The following blueprint shows an example part with all of the details noted for the switch and faceplate. It’s typical of what a finished blueprint would look like for a custom membrane switch. Graphic Overlay– Graphic overlays are typically constructed of polyester, the material of choice due to its superior chemical resistance and flex life compared to polycarbonate. CSI can either digitally print, screen-print, or employ a combination of both methods to insure you get the right colors, textures, and finishes your Silver Flex membrane switch design requires. In fact, advanced technologies in Hoffmann + Krippner membrane switches open completely new avenues for product design in these areas, including antimicrobial surface preparation . Additionally, due to its high voltage and frequency, EL lighting is often not permitted in medical technology, while H + K’s LED-based keypad lighting can be used freely.

It is the most ideal substrate for making thin film switch circuit. Textured pet is the preferred material for membrane switch panel. Reliatrace offers a wide range of both stainless steel and polyester domes to provide tactile feedback. High-quality metal snap domes are recommended for most applications, which give more solid tactile feedback, and provide higher reliability in the extreme temperature ranges of harsh environments. Stainless steel domes are available in a wide range of options, with sizes ranging from 4mm to 25mm, and a variety of thicknesses and actuation forces. Custom options are also available, which can be produced with minimal lead time. Depending on industry and application, membrane switches are also referred to as membrane keyboards and membrane keypads. Consequently, our custom membrane switches can be incorporated into full turnkey solutions that solve almost any technical need or challenge, complete with expert design and engineering from Hoffmann + Krippner.
SCHURTER has been a leader in the design and manufacture of membrane switches since the introduction of the membrane keypad technology was first introduced in the late 1970’s. We use nanotechnology to create dirt-repelling overlays that protect against any kind of contamination and mechanical damage. The front foil of every Hoffmann + Krippner membrane switch is printed from the back side. The upper layer of the membrane switch, with its sandwich construction, offers effective protection and the overlay can be easily cleaned and disinfected. Double contact membrane switches offer enhanced security and maximum reliability through keys with two switch levels. A speed function (slow/fast) controlling a crane, for example, requires two distinctly different switching functions. Hoffmann + Krippner has developed membrane switches with double contact functions specifically for such requirements. For example, the first switching level is activated at a pressure of around 7N, and the second level at about 13N. A membrane switch, also called a membrane keyboard or membrane keypad, is a momentary switching device comprised of a series of flexible layers of polymer films and adhesives.
The membrane switch assembly system generally has a total thickness between 1.0 and 1.5 mm. it is only equivalent to the thickness of an ordinary aluminum panel. The main eight different types of membrane switches include these as below. Of any of these three HMI options, membrane switches offer the best price point. Again, since they are so much easier to produce , they prove the lowest per-piece price and also the lowest tooling costs. Another main reason we see membrane switches all over the place in medical facilities and gyms has to do with how hygienic they are. Crevices between buttons on mechanical switches traps contaminants and germs.
Available in different textures, finishes & colors with holes, windows & embossing. Capabilities include flexographic printing, sub-surface printing, thermal imprinting, painting, engraving, embossing, bar coding, UPC coding, die cutting, butt cutting & short production runs. All these features culminate in multiple types of feedback while typing. There are typically both audible and an increased resistance when a keystroke is successfully actuated. While this will greatly benefit an experienced touch typist, even those learning to touch type will find their speed and accuracy improved. Of course, the time that is wasted looking at the screen to ensure that the correct characters are displaying will be regained. About the only person that doesn’t benefit from a mechanical keyboard is a hunt and peck typist . Sytek Enterprises Inc is a global leader in the design and manufacture of innovative human-machine interface products such as labels, membrane switches, force sensing resistors and much, much more.

Here is a brief overview about how to install a membrane switch correctly. You can also download the pdf file for step-to-step installation guidance. Graphic overlays to resemble a wider surface, including glass, metal wood, etc. The circuit also uses various layers including polyamide, polyester as well as rigid PCB layers. One way to distinguish between two different methods of creating a tactile response is whether or not the tactile layer is caused by the elastomer itself or from something beneath the rubber layer. Even though the entire switch package is made from flexible materials there are many options available. In general, polyester is more robust and has superior lifecycle and chemical resistance properties. For example, in lifecycle testing, polyester shows no signs of wear after even 1 million cycles. Due to its memory properties, polyester often requires hydroforming rather than embossing.
Electroluminescent is a traditional backlighting solution that uses EL bulbs to illuminate the switch’s buttons from behind. In addition to EL, light-emitting diode is a common backlighting solution for membrane switches. EL and LED backlighting can even be used with optical fiber to distribute their respective light more evenly across the membrane switch. This is an accelerated environmental test, accomplished by the continuous exposure of the test specimen to high relative humidity at an elevated temperature. Absorption of moisture by many materials results in swelling, which destroys their functional utility, causes loss of physical strength, and changes in other mechanical properties. Insulating materials which absorb moisture may suffer degradation of their electrical properties. The switch actuation force was measured using a calibrated force gauge. Both membrane switches required the same force to close the dome switch. Since the dome switch itself and the overlay/spacer layers drive the keypad’s tactile response, it’s no surprise the two membranes have the exact same tactile response. For machine-actuated applications, a “non-tactile membrane switch” may be a more economical solution.

And the maximum line screening is 230 LPI for process printing and graduated halftones. Membrane switches are often used in microprocessor-based control systems that you find in communication, appliance, instrumentation, and medical products. Custom membrane switches should add to your machine’s aesthetics, make them safer for users, and ensure that operators can get the most out of every feature. However, to work most effectively, this backlighting must entail the right light quality, intensity, color, and coverage for the specific environment in question. Graphic Overlay – This is the interface operators will interact with when using your machines. We make these out of polyester instead of polycarbonate because it is a much more chemically resistant material and offers superior flex life. This capability inherently eliminates the risk of fracture, providing you with greater flexibility in the design and location of your tail exit.
