Membrane switch is also called Touch Keypad, it utilizes PET, PC, FPC and other flexible materials and screen printing technology, which is an entirely sealed plastic electronic product that combines graphics, keys, signs, conductivity, and switch function. 1ï&frac*4;Membrane switch has below main advantages. ãããã1ï&frac*4;Small and portable. Generally a membrane switch is several or dozens ããããã grams, it is quite convenient to carry or disassemble. ãããã2ï&frac*4;Aesthetic appearance. It adopts advanced silk screen printing technology, ããããã with special design; we can provide any custom solution you need. ãããã3ï&frac*4;Sealing. To meet customer&#**9;s unique needs of the program, we can design ããããã the membrane switch to be water- proof, grease proofing, dust-proof, and ããããã ***** with unique technologies, the membrane switch can endure a ããããã high voltage. ãããã4ï&frac*4;Good conductivity. The circuitry is printed with carbon, silver, copper foil and ããããã so on, it can be freely folded, and the resistance can be limited according to ããããã customer&#**9;s specification. ãããã5ï&frac*4;Low cost. Membrane switch is low price, some even costs only cents. ããããã Compare to other electronic components which have same function, it is ããããã exactly cheap price. ãããã6ï&frac*4;Long lifetime. The materials are with high isolation, thermal resistance, fold ããããã resistance and rebound resilience. Moreover, the graphic can not be ããããã damaged because of its second surface printing; the lifetime is usually ããããã above 3 years. 2ï&frac*4;Product&#**9;s direction: ããTo analyze products in current market, most of them are getting to be short, small, ããlightweight and thin. Membrane switch is just in accordance with this design, which ããis an electronic component that in combination of art and technology. 3ï&frac*4;Type of membrane switch: ããMain types: There are many different types and layouts of membrane switch, its ããããããããbasic function like travel, operating force, life time mainly depend on ããããããããtype of key and material. The main types can be sorted as follows: ããããããããMembrane switch with flat keys, membrane switch with embossed keys ãããããããã(rectangle or dome), membrane switch with metal dome or polydome, ããããããããtactile or non-tactile, membrane switch with LCD window or embedded ããããããããLED, and so ***** 4ï&frac*4;According to the tactile feeling, it can be classified to 3 types. ã* Metal dome keypad: it has metal domes inside, with contacts above them, the ãããããããããããelectric loop is generated by finger operating. ãããAdvantage: 1) Good tactile feeling. ããããããããã2) Long lifetime even being used in high temperature condition. ã* Polydome keypad: Poly dome is an embossed dome in the circuitry layer of ããããããããããmembrane switch, it is quite durable, and the travel is a ããããããããããlittle shorter than metal dome keypad. In some applications, ããããããããããthe polydome can be processed in top overlay layer, this reduces ããããããããããnumbers of layer. Operating force is influenced by material ããããããããããthickness, diameter and height of the keys. ãããAdvantage: 1) Quite durable. ããããããããã2) It can be well operated for millions of times. ã* Non-tactile keypad: no tactile feeling, for non-tactile membrane switch, it generally ããããããããããããutilizes other way to show what the Keysâ status is. ãããAdvantages: 1) Available in big area. ããããããããã2) Lowest cost among all kinds of membrane switches. 5ï&frac*4; At TCF, we manufacture complete line of membrane switches, our experienced ããdesign team are ready to work with you to design membrane switches to meet ããyour unique needs of your project. ãã1) Graphic overlay with or without embossing. ãã2) Tactile with metal dome or polydome or non-tactile ãã3) Embedded LED or other surface mount components. ãã4) Waterproof or UV resistant. ãã5) Electroluminescent backlighting. ãã6) ESD shielding (Aluminum foil or whole layer with silver and carbon coated). ãã7) Tail with or without connector (male or female pin).
