1: 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.
7) Tail with or without connector (male or female pin).
2: Product's direction:
To analyze products in current market, most of them are getting to be short, small, lightweight and thin. Membrane switch is just in accordance with this design, which is an electronic component that in combination of art and technology.
3: 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...
A. Excellent flexibility
B. Reducing the volume
C. Weight reduction
D. Consistency of assembly
E. Increased reliability
F. Controllability of electrical parameter design
G. The end can be whole soldered
H. Material optionality
