II. Product Features
Dual-Process Compatible Design for Flexible & Efficient Installation
Innovatively integrating SMT surface-mount and vertical through-hole structures, the pins adopt a composite design of “SMT pad + through-hole pin”, allowing flexible installation according to PCB layout requirements. The SMT part supports automatic high-speed placement and synchronous soldering with other micro components to improve production efficiency. The vertical through-hole structure greatly enhances bonding strength, with significantly better vibration and shock resistance than single-process switches, perfectly adapting to complex assembly scenarios.
High-Temperature Resistant Materials for Harsh Soldering & Working Conditions
The switch housing is made of high-temperature resistant flame-retardant modified LCP engineering plastic, and pins are made of high-purity nickel-plated brass, capable of withstanding 260℃ reflow and wave soldering without deformation, softening, oxidation or detachment. The switch operates stably in a wide temperature range of -40℃ to 125℃, resisting thermal cycling shocks, meeting high-reliability standards for automotive electronics and industrial control.
Precise Press Feedback & Long-Life Stable Performance
Key travel is precisely controlled at 0.3–0.8mm, with operating force selectable from 160–500gf. The pressing process delivers clear tactile feedback, fast rebound and no sluggishness, with a trigger response time as short as 5ms to avoid false triggering. Internal silver-palladium alloy contacts provide excellent conductivity, oxidation resistance and arc erosion resistance, with contact resistance ≤50mΩ. The service life reaches 1,000,000 to 5,000,000 presses, far exceeding industry standards.
Compact Vertical Structure for High Space Utilization
Adopting a miniaturized vertical package with industry-standard dimensions, it occupies little front PCB space and can be vertically mounted on board edges or functional gaps. It perfectly meets high-density integration needs of consumer electronics, micro industrial control devices and other compact products, greatly improving layout flexibility.
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 stable and consistent mass production quality.
Standardized Compatibility for Lower Matching Costs
Pin spacing and package dimensions comply with industry common standards, compatible with Altium, Cadence and other mainstream PCB design software, requiring no additional board modification. The dual-process structure adapts to different production line processes, reducing equipment transformation costs caused by process changes and accelerating project progress.
Flexible Production Response for Efficient Customization
A modular production system supports customized requirements for special operating force, key travel and pin length 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.

V. FAQ
Q1: How to quickly select the suitable model for SMT high-temperature resistant vertical through-hole tact switch?
A1: Confirm via three core dimensions: ① Required operating force, key travel and pin length; ② PCB pad size (SMT part), mounting hole diameter & pitch (through-hole part) and soldering process requirements; ③ Operating environment (temperature, humidity, vibration frequency) and pressing frequency. Our technical team will provide accurate selection suggestions within 1 hour.
Q2: How to solve button failure or slow rebound during use?
A2: First disconnect power and check for cold solder joints or insufficient solder on through-hole pins or SMT pads; re-solder for reinforcement 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 dome may be damaged by overuse or impact; replace with a high-quality equivalent high-temperature resistant switch.
Q3: What key parameters are required for customization?
A3: Please provide: ① Basic specifications (key travel, operating force, pin length); ② Structural requirements (keycap color & shape, waterproof/dustproof requirement, positioning posts); ③ Performance requirements (temperature resistance grade, service life, vibration resistance grade); ④ Installation requirements (PCB pad size, mounting hole diameter & pitch, soldering process type); ⑤ Order quantity and delivery schedule. We will issue a detailed customization plan and quotation accordingly.
