The smart door lock membrane panel features a compact size, lightweight construction, excellent sealing properties, a novel appearance, extended service life (up to one million cycles), and high reliability.
Slim and Portable: Typically measuring 0.3–1.0mm in overall thickness and lightweight, it facilitates installation on smart door locks without adding excessive bulk or weight.
Waterproof and Dustproof: Employing a fully sealed construction with an IP67 protection rating, they effectively prevent ingress of water and dust, adapting to diverse operational environments.
Extended Lifespan: Contact points endure over one million cycles, with metal spring-loaded variants achieving up to five million cycles, meeting the demands of prolonged, frequent use in smart locks.
Aesthetic Customisation: Panels can be produced in various colours and patterns through processes like silk-screen printing, seamlessly integrating with the overall appearance of smart locks. Key shapes and tactile feedback can also be customised to specific requirements.
Strong Anti-Interference Capability: Possesses excellent resistance to electromagnetic interference, maintaining stable operation in complex electromagnetic environments to ensure accurate signal transmission.
The material selection for membrane switch panels in smart door locks directly impacts their durability, tactile feel, and service life.
PC film exhibits excellent high-temperature resistance (-30°C to 130°C), high transparency, and impact resistance, making it one of the most widely used materials for electrical panel switches. Its high dielectric strength and strong processing adaptability render it suitable for applications requiring high transparency and impact resistance.
PET film excels in household appliance panels, offering good switch key longevity, corrosion resistance, abrasion resistance, and insulation properties. Its high toughness and tensile strength make it suitable for high-frequency use devices (such as washing machines), effectively extending product lifespan.
PVC film offers a lower cost, excellent chemical resistance, and superior insulation properties. However, its limited elasticity generally precludes its use in membrane switches or tactile panels requiring frequent operation. It is more commonly employed in signage-type panels.
