II. Product Features
Dual Structure for Flexible Adaptation & High Space Utilization
Integrating both through-hole push and submerged reset core designs. The through-hole version features sturdy pins for through-hole mounting; the submerged SMT version adopts an ultra-low-profile structure, 30% thinner than conventional tact switches, allowing embedded installation inside the PCB. It perfectly fits the ultra-thin, miniaturized design trend of modern devices and greatly saves layout space.
Precise Press & Reset with Clear Tactile Feedback
Key travel is precisely controlled at 0.2–0.4mm, with operating force selectable from 100–500gf. The pressing action is smooth without jamming or sluggishness, and trigger response is instant. Built-in high-elasticity reset spring ensures even rebound force and a reset time as short as 5ms, returning to the original state immediately upon release, ideal for high-frequency, high-precision on-off control.
High-Reliability Contact Design for Long Service Life
Internal contacts are made of silver-palladium alloy with excellent conductivity, oxidation resistance and arc erosion resistance, effectively lowering contact resistance and ensuring stable, interference-free signal transmission. The service life reaches 1,000,000 to 10,000,000 presses, far exceeding industry standards, resisting poor contact or failure even under long-term heavy use.
Wide-Temperature Weatherability for Strong Environmental Adaptability
Housing uses high-temperature resistant flame-retardant PC engineering plastic with outstanding mechanical strength and anti-aging performance, operating stably from -40℃ to 120℃ and resisting thermal shock. It features excellent moisture and corrosion resistance, maintaining performance in 10%–95% relative humidity and mild dust/oil environments, suitable for harsh working conditions across industries.
III. Product Advantages
Digital Manufacturing Control for Excellent Quality Consistency
Equipped with an MES digital production management system that monitors stamping pressure, mold temperature, key travel and other key parameters in real time, with deviations controlled within ±0.1kN and ±1℃. A multi-camera visual inspection system accurately identifies 12 types of defects including skewed pins, contact oxidation and housing deformation, with a defect rate below 0.1%, ensuring consistent mass production quality.
Standardized Compatible Design for Lower Adaptation Costs
Pin spacing and package dimensions comply with universal industry standards and are compatible with mainstream PCB design software such as Altium and Cadence, requiring no design modifications. The through-hole version supports wave soldering, while the submerged SMT version is compatible with automatic SMT assembly, enabling synchronous production with other components and reducing customer matching costs.
Flexible Production Response for Efficient Customization
A modular production system supports customized requirements for special operating force, key travel, pin length and submerged depth with a response speed 45% faster than the industry average. Standard models are in stock and deliverable within 72 hours. Customized products offer one-stop service from structural design and prototyping to mass production, with a minimum sample lead time of only 3 working days.
Full-Cycle Service Guarantee for Worry-Free Cooperation
Supported 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, fully meeting strict compliance requirements in automotive, medical and other high-end industries.

V. FAQ
Q1: How to quickly select the right model for through-hole push switch & submerged reset SMT tact switch?
A1: Confirm via three core dimensions: ① Specify type (through-hole push / submerged reset SMT), operating force, key travel, pin length (through-hole) or submerged depth (SMT); ② Provide PCB mounting hole diameter & pitch (through-hole) or pad size (SMT) and soldering process requirements; ③ Describe operating environment (temperature, humidity, vibration frequency) and pressing frequency. Our technical team will provide accurate suggestions within 1 hour.
Q2: How to solve button failure or slow reset during use?
A2: First disconnect power and check for cold solder joints or insufficient solder on pins/pads; re-solder if needed. If soldering is normal, gently wipe internal contacts with anhydrous alcohol and an ultra-fine cotton swab to remove dust or oil, then test after full drying. If the problem continues, the internal spring may be damaged by overuse or impact; replace with a high-quality equivalent product.
Q3: What key parameters are required for customizing this switch?
A3: Please provide: ① Basic specs (type, key travel, operating force, pin length / submerged depth); ② Structure (keycap shape, color, waterproof/dustproof requirement, positioning posts); ③ Performance (temperature range, service life, vibration resistance); ④ Installation (PCB hole/pad size, soldering process); ⑤ Order quantity and delivery time. We will issue a detailed customization plan and quotation accordingly.
