II. Product Features
Ultra-Miniature & Ultra-Slim Design for High Space Utilization
Adopting an ultra-compact 2mm×3mm×0.65mm package, only one-third the thickness of conventional thin-film switches, making it one of the thinnest specifications in the miniature switch field. The lead-free SMT surface-mount design allows direct mounting on the PCB surface without reserved via space, perfectly meeting the high-density integration requirements of ultra-small devices such as smart wearables, micro sensors and ultra-thin medical probes, providing ample margin for lightweight and miniaturized equipment design.
High-Temperature SMT Process for Strict Welding Standards
The switch base uses high-temperature resistant polyimide film, and the conductive layer is printed with nano-silver paste, capable of withstanding 260℃ reflow soldering without deformation, warping or conductive layer detachment. It fits tightly with the PCB after soldering with no residual stress, meeting high-reliability welding requirements for automotive electronics and industrial control, adapting to large-scale automated SMT production lines and improving assembly efficiency.
Silent Tactile Feedback for Precise & Delicate Operation
Key travel is precisely controlled at 0.1–0.2mm, with operating force as low as 80–150gf. The pressing process is silent and noise-free, with soft and clear tactile feedback, and a trigger response time as short as 3ms to avoid false triggering. The thin-film contacts are treated with an anti-oxidation coating, maintaining stable contact resistance ≤80mΩ for delay-free and crosstalk-free signal transmission, suitable for scenarios with strict requirements for silence and precise control such as medical equipment and portable audio devices.
High Stability & Excellent Environmental Adaptability
The switch operates stably in a wide temperature range of -40℃ to 85℃, resisting thermal cycling shocks. It features excellent moisture and corrosion resistance, maintaining performance in 10%–95% relative humidity and mild dust/oil environments. Withstanding over 200,000 bending cycles, it supports bending installation on flexible PCBs, ensuring long-term stable operation under complex working conditions.
III. Product Advantages
Digital Manufacturing Control for Excellent Quality Consistency
Equipped with an MES digital production management system that monitors film printing thickness, key travel, mounting accuracy and other key parameters in real time, with deviations controlled within ±0.005mm. A high-precision visual inspection system accurately identifies 10 types of defects including contact offset, conductive layer damage and mounting skew, with a defect rate below 0.08%, ensuring stable and consistent mass production quality.
Standardized Compatible Design for Lower Adaptation Costs
Package dimensions and pad definitions comply with industry common standards, compatible with Altium, Cadence, KiCad and other mainstream PCB design software, requiring no additional board modification. The SMT structure allows synchronous soldering with micro components such as resistors and capacitors, reducing production line changeovers and lowering labor and material costs.
Flexible Production Response for Efficient Customization
A modular production system supports customized requirements for special operating force, key travel and dimensions with a response speed 50% faster than the industry average. Standard models are in stock and deliverable within 72 hours. Relying on in-house mold development and thin-film printing technology, customized products offer one-stop service from structural design and prototyping to mass production, with a minimum sample lead time of only 2 working days.
Full-Lifecycle Service Support for Worry-Free Cooperation
Backed by a professional technical team providing selection guidance, soldering process optimization and troubleshooting, with an after-sales response time within 24 hours. Products support forward material traceability and reverse defect tracing, with full-process production data accessible in real time, fully complying with strict automotive, medical and industrial automation compliance requirements.

V. FAQ
Q1: How to quickly select the suitable model for 2×3×0.65 SMT high-temperature miniature thin-film tact switch?
A1: Confirm via three core dimensions: ① Required operating force and key travel; ② PCB pad size and reflow soldering temperature profile parameters; ③ Operating environment (temperature, humidity, bending requirement) and pressing frequency. Our technical team will provide accurate selection suggestions within 1 hour.
Q2: How to solve unresponsive buttons or unclear tactile feedback?
A2: First disconnect power and check for cold solder joints or detachment on pads; re-solder for reinforcement if needed. If soldering is normal, gently wipe the switch surface with anhydrous alcohol and an ultra-fine cotton swab to remove dust or oil, then test after full drying. If the problem continues, the thin-film contacts may be damaged by external compression; replace with a high-quality equivalent high-temperature miniature thin-film switch.
Q3: What key parameters are required for customization?
A3: Please provide: ① Basic specifications (dimension modification, key travel, operating force); ② Structural requirements (key pattern, waterproof requirement, pad position); ③ Performance requirements (temperature resistance grade, bending cycles, operating temperature range); ④ Installation requirements (PCB pad size, maximum reflow soldering temperature); ⑤ Order quantity and delivery schedule. We will issue a detailed customization plan and quotation accordingly.
