At the heart of electronic control systems, every switch actuation carries the critical task of precise command transmission. Shenzhen Kinghelm Electronics Co., Ltd. presents the Kinghelm KH-6X6X12H-TJ through-hole tactile switch—a 6mm×6mm×12mm compact solution that integrates high electrical performance with mechanical durability, delivering trusted tactile control for industrial equipment, household appliances, and communication devices.

Featuring a classic black circular button, this SPST (Single Pole Single Throw) switch is engineered for DC 12V/50mA circuits. Its through-hole PC pins ensure secure PCB mounting, while the scientifically calibrated 260±30gf operating force delivers crisp tactile feedback—preventing accidental triggers while minimizing operational fatigue. Compatible with both manual soldering (350°C max) and automated reflow processes (270°C max), the housing withstands thermal stress without deformation, guaranteeing production consistency.

Electrical safety defines Kinghelm's core engineering principles. The Kinghelm KH-6X6X12H-TJ achieves an ultra-low contact resistance of ≤30mΩ (tested at 100mA), minimizing signal loss. Its 100MΩ insulation resistance (DC100V/1min) creates robust circuit isolation, while AC250V/0.5mA withstand voltage testing eliminates breakdown risks. Mechanical integrity is rigorously proven: terminals endure 150gf lateral static loads without damage, and after 100,000 no-load cycles (20 cycles/minute), contact resistance remains stable below 200mΩ with uncompromised responsiveness.

The switch excels in harsh environments. From -25°C storage to 70°C operation, through 96-hour dry heat aging at 85°C and high-humidity exposure (40°C/96% RH), the silver-plated contacts and engineering plastic housing maintain consistent performance. This thermal resilience supports applications like microwave control panels, industrial instrument switches, and router reset buttons in automotive cabins, dusty factories, or humid households.

Notably, its 6mm×6mm footprint and 12mm profile optimize space utilization in compact layouts. At just 0.336g, it reduces device payload and logistics costs, with bag packaging streamlined for production efficiency.

To ensure full lifecycle reliability, Kinghelm engineers advise: always disconnect power before installation to prevent electrostatic discharge; avoid exceeding 300gf operating force to protect internal springs; and consider sealed enclosures in corrosive atmospheres. Every switch undergoes multi-stage electrical testing and mechanical stress screening, adhering to eco-friendly materials and plating processes.
