The faceplate material for membrane switches predominantly utilises polyester-based materials, primarily comprising polyvinyl chloride (PVC), polycarbonate (PC), and polyethylene terephthalate (PET). Each material possesses distinct advantages and disadvantages, allowing selection based on specific requirements. Factors such as flex life, chemical resistance, abrasion resistance, insulation properties, window transparency, embossing clarity, temperature rating, and UV resistance may serve as reference criteria for selection. Regarding the classification between plastic films and sheets, no unified standard currently exists. Based on thickness, they can be categorised as films, sheets, or plates. According to the German DIN 55405 standard, materials thinner than 1.5mm are termed films, while those exceeding 1.5mm are designated as plates. In China, it is customary to refer to materials under 0.3mm as film, those between 0.3-0.7mm as sheet, and those over 0.8mm as plate. Given the limited thicknesses typically employed in nameplate manufacturing, it is common practice to collectively term both film and sheet as film.
1. Compact and lightweight: Typically weighing between a few grams and several dozen grams, membrane switches are highly portable and easy to install or remove;
2. Aesthetically pleasing: Modern, sophisticated screen printing techniques combined with impeccable design enable the creation of any desired pattern;
3. Sealed construction: Utilising proprietary technology, membrane switches can be engineered to be waterproof, oil-resistant, contamination-proof, and shielded against electrostatic interference;
4. Superior Conductivity: Switch circuits can be printed using carbon paste, silver paste, or copper-platinum, with conductive layers capable of being freely folded. Resistance values are controllable to meet any required specification. Moreover, employing proprietary techniques, the resulting membrane switches can withstand high-voltage shocks exceeding hundreds of thousands of volts without functional impairment;
5. Low cost: Some membrane switches retail for mere pence. For an electronic component offering such multifunctionality, its price advantage remains unmatched by comparable products.
6. Extended service life: The materials employed in membrane switches exhibit excellent insulation, heat resistance, flexural strength, and high resilience. Furthermore, reverse printing techniques are used for pattern application, safeguarding the silk-screen patterns from damage. Consequently, membrane switches typically achieve a service life exceeding three years.
Clear Patterns: Screen printing delivers exceptionally crisp results, enabling high-precision pattern reproduction.
Superior Wear Resistance: Screen-printed inks exhibit high abrasion resistance, ensuring long-term durability for membrane switches.
Vibrant Colours: Screen printing offers a rich palette of inks, facilitating multi-colour printing capabilities.
