What are the material types of membrane switches?

Polyvinyl chloride, PVC\60, \0.175~0.5/, smooth, acid, base and salt stability at room temperature. Good wear resistance, fire resistance, self extinguishing, noise elimination, shock insulation, good electrical insulation. Poor thermal stability. Cheap ordinary signs, panels.

Polycarbonate PC\-60~120 C \0.175~1.0\ smooth high transmittance, low water absorption, good dimensional stability, bending, tensile and compressive strength is excellent heat resistance, cold resistance, electrical insulation and excellent resistance to atmospheric aging. The drug resistance is bad, and the fatigue resistance is poor, and it is easy to produce stress

Thin film switch

Thin film switch

Split, output interface terminal circuit is generally made of carbon materials, printing, and no protective coating, by air oxidation gradually formed abscission layer, to finally lead to open circuit and end of life, this is the most prone to failure of the thin film switch, mainly depends on the environment, regardless of whether or not the physical damage time is 3-10. Generally applicable to the most extensive, in addition to meet the requirements of most of the membrane switch panel, of which the smooth PC high transmittance can meet the requirements of LCD window.

Sand surface polyester (PET) \-30~120 DEG \0.1~0.2, smooth surface, good drug resistance, insoluble in general organic solvents, no alkali resistance. With excellent mechanical properties, electrical properties, rigidity, hardness and thermoplastic maximum strength and toughness, low water absorption, wear resistance, good friction resistance, high dimensional stability. The tensile strength is comparable to that of aluminum film, much higher than that of PC and PVC. Low because the surface is hard to be processed into Matt type, so it is the most expensive texture PET substrate making ideal film switch circuit. Among them, texture PET is suitable for products with high surface requirement or liquid crystal display window.
