100% Electrical Inspection Enterprise Overview · Since 1990
Three Decades of Precision Membrane Switch Engineering
TAVO Electronic Information Technology Co., Ltd. was established in 1990, dedicated to the professional research, development, and high-precision manufacturing of custom membrane switches, membrane keypads, and graphic overlays. Over more than 30 years of continuous growth, flexible copper FPC membrane switches, LED backlit membrane switches, and membrane switches with rigid backers have evolved into our core competencies.
Our human-machine interface (HMI) products are widely specified across industrial automation, household appliances, analytical apparatus, medical equipment, and harsh outdoor operating environments. Guided by a core principle of customer-centered solutions, uncompromising integrity, and rapid delivery at competitive total costs, our facilities operate in strict compliance with the ISO 9001 quality management system.
Through sustained investment in automated manufacturing and technical engineering, our products have earned comprehensive recognition across the international market. Backed by nearly ten years of close technical and commercial collaboration with OEM partners in the United States, Germany, and across European countries, our custom switches have successfully served mission-critical engineering initiatives, including high-speed railway locomotive control systems, the Three Gorges Project, aerospace equipment, and key international industrial developments.
