Membrane switch is also called Touch Keypad, which made by flexible insulation layer compaosed of a multiayer structure (plane). Due to aesthetic appearance, long lifetime and simple struture, it's widely used in mechanical equirements, instrument, medical equirements and other lines.Type of membrane switch:
Main types: There are many different types and layouts of membrane switch, its basic function like travel, operating force, life time mainly depend on type of key and material. The main types can be sorted as follows:
Membrane switch with flat keys, membrane switch with embossed keys (rectangle or dome), membrane switch with metal dome or polydome, tactile or non-tactile, membrane switch with LCD window or embedded LED, and so on...Membrane switch has below main advantages.
1)Small and portable. Generally a membrane switch is several or dozens grams, it is quite convenient to carry or disassemble.
2)Aesthetic appearance. It adopts advanced silk screen printing technology, with special design; We can provide any custom solution you need.
3)Sealing. To meet customer's unique needs of the program, we can design the membrane switch to be water- proof, grease proofing, dust-proof, and static-free...With unique technologies, the membrane switch can endure a high voltage.
4)Good conductivity. The circuitry is printed with carbon, silver, copper foil and so on, it can be freely folded, and the resistance can be limited according to customer's specification.
5)Low cost. Membrane switch is low price, some even costs only cents. Compare to other electronic components which have same function, it is exactly cheap price.
6)Long lifetime. The materials are with high isolation, thermal resistance, fold resistance and rebound resilience. Moreover, the graphic can not be damaged because of its second surface printing; The lifetime is usually above 3 years.Supporting products:
