PET membrane switches are flexible circuit control panels manufactured from polyester (PET) film, offering advantages such as lightweight construction, high sensitivity, and robust environmental adaptability. They find extensive application across medical, domestic appliance, and industrial control sectors.
Superior Mechanical Properties
Features a rocker-style dual-contact design with spring-return mechanism, delivering over 5 million press cycles. Exhibits high flex resistance and tensile strength.
Exceptional Environmental Adaptability
Resistant to chemical reagents and household cleaners, with waterproof and dustproof capabilities (IPX4 rating). Operates within a temperature range of -20°C to +70°C, suitable for humid or dusty environments.
Compatibility with Printing and Surface Finishes
Printable surfaces support screen printing with strong ink adhesion. Compatible with liquid window printing for transparent areas and sand-finish screen printing processes, delivering an aesthetically pleasing and wear-resistant appearance.
Structural and Cost Advantages
Utilising PET film as the circuit substrate ensures lightweight construction and cost-effective production, ideal for mass manufacturing. Compared to traditional switches, it offers superior sealing, waterproofing, and extended service life.
Industrial instrument membrane switches employ a multi-layer sealed structure achieving IP67 protection, effectively isolating against moisture, oil contamination, dust, and corrosive gases. Suitable for demanding environments such as high humidity and dust, they occupy only 60% of the volume of traditional mechanical switches with significantly reduced weight. Flexible circuits can conform to curved panels, simplifying installation and saving equipment space.
Waterproof and Dustproof
Featuring a sealed structural design, it effectively prevents ingress of water, dust, oil contamination, and harmful gases, making it suitable for diverse harsh environments.
Exceptional Durability
With a service life exceeding one million operations, the switch action is achieved through vertical elastic deflection of the membrane, ensuring stable and reliable structural performance.
Rich Colour Palette
Screen printing technology supports customised pattern designs, enhancing the visual appeal of instrument panels.
