Three Decades of Precision HMI & Membrane Switch Manufacturing
TAVO Electronic Information Technology Co., Ltd. was established in 1990 as a pioneer concentrated on the design, processing, and advanced material research of custom membrane switches, membrane keypads, and graphic overlays. Over more than three decades of continuous technical expansion, flexible copper FPC membrane switches, LED backlit membrane switches, capacitive touch panels, and membrane switches with rigid backers have evolved into our core competence.
Our products are widely integrated across high-reliability sectors including industrial automation, medical diagnostic apparatus, intelligent household appliances, precision instrumentation, and aerospace systems. Operating under a customer-centered, integrity-based philosophy, we uphold the operational principles of high quality, rapid response, and optimized total cost of ownership.
All manufacturing facilities and procedures strictly conform to the ISO 9001 international quality management framework, verified by independent on-site audits conducted by Intertek.

Full Environmental, Life-Cycle & Electrical Testing
To guarantee field durability, our on-site inspection laboratory replicates harsh operational climates, prolonged physical fatigue, UV degradation, and chemical exposure prior to shipment.
Computer Tester
Performs 100% automated electrical checks across all circuit traces, verifying loop resistance, contact bounce (≤5ms), short circuits, and open isolation.
Button Life Cycle Test Unit
Automated pneumatic actuators exert controlled displacement and force curves to validate tactile metal dome switches exceeding 1,000,000 actuations.
Humid & Temp Programmable Tester
Simulates continuous temperature (-40°C to +150°C) and relative humidity cycles up to 98% RH to evaluate layer adhesion, ink curing, and trace stability.
Xenon Lamp Aging Test Chamber
Full-spectrum solar UV simulation evaluates colorfastness, anti-yellowing behavior, and graphic overlay substrate embrittlement under outdoor exposure.
Auto Salt Fog Chamber
Continuous ASTM B117 neutral salt spray testing verifies perimeter seal integrity and prevents trace corrosion on maritime and outdoor equipment panels.
Visual & Dimensional Inspection Station
High-resolution optical magnification stations check alignment registration (±0.05mm), window clarity, surface embossing height, and edge finish.
Modern Workshops & Advanced Machining Centers
With zero outsourcing of critical manufacturing steps, TAVO maintains total control over design conversion, precision screen/UV printing, cleanroom assembly, and laser cutting.
