Advantage of membrane panel
1. Beautiful appearance, rich and bright in color, design can be arbitrary, the products can fully reflect the individual style of the product itself and designer.
2. Panel can wash, good protection of durable color, characters, logos and other panel contents without injury.
3. Small size, light weight, thin thickness, good tactility, abrasion resistant, installation and connection convenience.
4. Tightness is good, moisture-proof, dust-proof, waterproof, anti-oil, anti-corrosion and erosion of harmful gases proof, acid and alkali proof, quakeproof.
5. Low cost, high lifespan, membrane switchs design and manufacture are using the keyboard as a whole way, whether on the material or mold charges, the costs are lowest, the life expectancy of different types of membrane switch is more than 100 million times.
6. Easy to operate, intuitive, safe and reliable, In-house 100% functionally tested, components are guaranteed without any intermittent problem.
