II. Product Features
5.8×5.8mm Flat Head Horizontal Design for Space Saving
Adopting a 5.8×5.8mm micro square package with a flat head button structure, the switch features a smooth and concise surface that can be directly mounted on the PCB surface without reserved protruding space. The horizontal installation allows the switch to be arranged parallel to the PCB, and the compact layout of single-row 3 pins greatly reduces board space occupation. It is perfectly suitable for high-density integration of ultra-thin and narrow-body electronic devices, especially compact instruments and smart wearable products with limited space.
Single-Row 3-Pin Structure for Flexible Functional Adaptation
The single-row 3-pin design enables single-circuit on-off control. The combination of common terminal, normally open and normally closed contacts flexibly meets the control needs of different circuits, eliminating the need for additional adapter circuits and simplifying equipment circuit layout. Pin spacing complies with industry universal standards for clear identification and precise positioning during soldering, effectively reducing difficulties in manual assembly and automated SMT placement.
SMT Compatibility for Automated Production
Featuring standard SMT pin design, the switch is fully compatible with automated SMT production lines. It can complete feeding, printing, placement and soldering synchronously with other SMT components without separate production line adjustments, greatly improving mass production efficiency and reducing labor costs. The switch housing is made of high-temperature resistant flame-retardant engineering plastic, capable of withstanding 260℃ reflow soldering without deformation, softening or cracking, ensuring stable product performance after placement.
High-Sensitivity Press Feedback and Excellent Durability
Built with precision beryllium copper alloy elastic reeds, it delivers uniform and moderate actuation force, clear and rapid rebound feedback without jamming or lag. The flat head surface offers a smooth touch, reducing fatigue even under high-frequency operation. The contacts are made of high-purity silver alloy with low contact resistance and excellent electrical conductivity, effectively avoiding poor contact and signal fluctuation. The mechanical life of the switch reaches over 1 million cycles, meeting long-term high-frequency usage requirements.
III. Product Advantages
Precision Manufacturing for Stable and Reliable Quality
Introducing an MES digital production management system, we monitor key process parameters such as injection mold temperature, stamping precision and contact plating thickness in real time, with parameter deviation controlled within ±0.005mm. Equipped with a multi-camera linked visual inspection system, it accurately identifies defects including insufficient flatness, skewed pins and offset contacts, keeping the product defect rate below 0.05% and ensuring consistent quality in bulk delivery.
Standardized Design for Lower Adaptation Costs
Product pin spacing and pad definitions conform to industry universal standards, compatible with library files of mainstream PCB design software such as Altium and Cadence, eliminating the need for customers to adjust board designs or customize stencils. It directly matches mainstream SMT reflow soldering process parameters without additional temperature zone adjustments, significantly reducing selection and production adaptation costs and accelerating project progress.
Flexible Production with Efficient Customization Response
We have established a modular production system, with a 50% faster response speed than the industry average for customer requests such as actuation force adjustment, button travel customization and pin length modification. Regular specifications are kept in stock for delivery within 72 hours. For customized products, we provide one-stop services from structural design and sample prototyping to mass production, with a minimum sample lead time of only 2 working days.
Full-Cycle Service for Worry-Free After-Sales Support
Staffed with a professional technical service team, we provide early selection guidance, mid-term soldering process optimization support and post-sale troubleshooting services, with an after-sales response time of no more than 12 hours. The product supports full-process quality traceability, fully meeting stringent compliance requirements in automotive electronics, medical devices and other fields, providing comprehensive cooperation guarantees for customers.

V. FAQ
Q1: What key parameters need to be confirmed for product selection?
A1: Three core points shall be confirmed: ① Actuation force and travel requirements to match equipment operation feel; ② PCB thickness, pad size and reflow soldering temperature profile; ③ Application environment (temperature, humidity, operation frequency) and circuit control requirements. Our technicians will provide a precise selection proposal within 1 hour.
Q2: How to deal with insensitive button rebound during use?
A2: First, cut off power and check for dust or debris jamming on the switch surface; dry compressed air can be used to gently blow the button gaps. For soldering issues, confirm if excessive soldering temperature caused reed deformation, and re-solder after adjusting soldering parameters. In case of mechanical structure damage, replacement with the same specification product is recommended.
Q3: Does the product support waterproof customization?
A3: Waterproof rating upgrade customization is supported. By adding waterproof silicone rings and optimizing housing sealing structures, the product protection rating can be upgraded to IP65, meeting special application scenarios such as outdoor equipment and waterproof instruments. Detailed waterproof application requirements and bulk order quantity shall be provided.
