More common on digital versions of these appliances, the control panel is often made up of a membrane switch assembly. Some gym equipments like the treadmill also has these type of controls which are often used ruggedly but stays reliable for a long time. UV cure surface textures and glosses can be applied to further enhance the appearance and functionality of membrane keypads. Gloss enhances clarity for displays while anti-glare and matte conceal fingerprints.In certain applications an anti-microbial finish may enhance product performance. These are the basic layers of a membrane switch, meaning it will be touched and activated by users. The response is typically a ‘snap’ or ‘click’ when the switch is depressed. This is usually a function of the dome switch that is selected for the application. You can design the size, force, and snap required to activate the switch. The same function can usually be achieved with a traditional toggle switch but constructed from bulky metal or plastic parts.
These assemblies have three parts, the electrical switch , the plastic locking nut , and the button . Rubber keypads provide a weather-resistant interface, and they are capable of withstanding exposure to moisture, dust, vibration, and shock. This makes them ideal for demanding environments and rugged applications. At PrintApp we can create circuit and front facia design out of almost anything including films, drawings, paper design or the keyboard itself. We have developed a systematic process to make sure that the features of the keyboard are double checked and replicated without error. With the consolidation of the field of Membrane Switches, many of our customers find themselves needing to order boards but they don’t have the design of the board or the circuit or both. Their previous supplier may have gone out of business or the keyboard supplied by them is too much costly.
Normally, keypads are designed with individual keys, each of which is a separate moving part. But membrane keypads take a step in a different direction by featuring pressure pads on which the key outlines and symbols are printed. This keypad has 4 buttons, and since every key has its own wire line, no matrix code is required – just treat these like every day switches. The membrane is soft and has a removable paper backing to expose a strong adhesive so you can stick this on an enclosure and feed the cable through a slot. We include a 5-pin extra-long header strip so you can plug this into a breadboard with ease. Quad industries offers a fully customized solution in the process of developing membrane keypads and switches.
In addition to normal protection against dust and moisture, the integrated acrylic inlay also protects the snap dome against possible deformation. Not even heavy point-specific pressure can damage the key areas. The electrical performance of these switches can also be varied depending on the specifications set for a particular device. The most common are that the loop resistance should be be less than 100 Ohms, while the open circuit resistance should be set at the minimum of 50 mega Ohms. The membrane switch should be able to function within the standards -20 °C to +75 °C as its operating temperature. The contact rating should stay within 100 Milli-amps at 28 VDC Maximum, while the contact bounce should be 5 milliseconds nominal. Modern membrane switches have also adapted to become water/moisture proof, heat/cold resistant and the front panels are designed so that they are easier to clean. Membrane keypads can have non-tactile, metal dome tactile and polydome tactile keys or buttons. And a combination of different tactile effects and forces can be combined in one membrane keypad product. The same is true for embossing where membrane keypads can combine pillow, rim or dome embossing with flat non-embossed keys.

These switches are resistant to shocks and vibrations so any moving device can perform normally without breaking the facility of the switch. The designs now also allows the addition of electronic components into the flexible switch substrate so it can adapt to some special attributes needed for a specific control panel system. Compared to the most common switches we see at home — the light switch, membrane switches are operated by generating a finger tip force in the keys within its panel. Often used with microprocessor based control systems, membrane switches have become an essential part of modern instrument, machine and appliance panels that have specialized functions in our daily lives. Using a membrane keypad can mean the switch circuit moves from the interior of the product to the outer surface. In the same way leds can be shifted from a PCB inside the device to the membrane keypad .
Silicone Rubber The most common remote control keypad material is silicone rubber. Different types of silicone can be used for different button feel . Most silicone rubber keypads provide a softer button press for the user. The silicone rubber keypads can also include silk screen printing. Silicone keypads can be colored to fit your design requirements. There are many components in designing a membrane switch but none more important than the graphic overlay. The overlay is typically the first part of the device that the user notices and helps the user identify how to control the device. Graphic overlays are one of the top-notch components of membrane switches that offer robust benefits.
Can you store any profiles on the keyboard and if so at least 3 to 5 profiles at any given time. Look for extra keys if you are buying for gaming as they will enhance your in-game experience. All keyboards come with backlighting nowadays but it is most sought after by gamers who need to be able to see the keys even in the dark. The mouse is unique in its own way; it has additional keys that enhance your gaming experience and you can customize the weight of the mouse to suit your style of use. This full-size keyboard with a 104-key layout improves your productivity. The ambidextrous mouse allows free and easy usage of the keyboard. The only negative in this keyboard is its price which is on the higher side, almost in line with the more adept and higher end keyboards. It is a full sized stylish keyboard with separate keys for volume and to control backlight which incidentally has three levels. This sleek keyboard from Logitech is good to look at and better to work with. Though the chassis is made of plastic it is sturdy and well built.
A membrane keypad with no embossing has a completely smooth surface. For keyboards with flat keys without embossing, it is often an advantage that the key provides the user with feedback when activated. With unlimited graphic design possibilities, customised membrane keypads and switches support both product expression and brand value of the overall solution. This innovative membrane switch material combines antimicrobial properties with a hard, durable surface. The antimicrobial protection is directly integrated into the hard-structured coating to ensure an even distribution of the antimicrobial agent across the entire overlay for the product’s service life. 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.
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.
