Space-Optimized Vertical Design

The KH-6X6X12H-STM reflects Kinghelm’s expertise in spatial efficiency. Its 6mm×6mm square base suits high-density PCB layouts, while the 12mm functional height provides sufficient travel for precise actuation without protrusion. The matte-finished black circular button aligns with modern device aesthetics. Featuring gull-wing pins for SMT mounting, it increases solder joint area for enhanced mechanical stress resistance and reduces soldering defects in automated assembly.

Verified Long-Term Reliability

This switch meets industrial-grade standards:

Electrical Performance: SPST structure ensures clear signal paths; 12V rated voltage and 50mA contact current support mainstream low-voltage applications

Mechanical Life: Validated 80,000 actuation cycles via 2,000 presses/minute endurance testing (equivalent to 2+ years at 100 daily presses)

Environmental Suitability: Silver-plated contacts resist oxidation; stable contact resistance within -25℃ to 70℃ operating range

Engineered User Experience

Kinghelm’s design optimizations include:

Staged spring plate structure delivering distinct two-stage tactile feedback (0.25±0.1mm travel)

Calibrated spring rate maintaining 300±30gf actuation force to balance anti-mishandling and comfort

R0.3mm rounded button edges for smooth fingertip contact

Multi-Industry Application Validation

The KH-6X6X12H-STM performs in demanding scenarios:

Smart Home: HVAC control panels and smart switches handling frequent operation

Industrial Control: PLC cabinets and instrumentation with ESD 8KV resistance

Automotive Electronics: In-car entertainment systems compliant with GMW3172 mechanical shock standards

Telecom Equipment: 5G testing modules maintaining signal stability under EMI

Kinghelm Quality Assurance

Every batch undergoes full-process controls:

Material Traceability: PC housing with UL94 V-0 flame rating

Process Monitoring: Pre-SMT X-Ray pin coplanarity inspection

100% Testing: Contact resistance/insulation resistance (>100MΩ) verification

Reliability Validation: Periodic 85℃/85%RH damp-heat testing

Usage Guidelines:

Recommended soldering: 260±5℃ for ≤3 seconds

Avoid prolonged exposure to sulfur/chloride corrosive environments

Maximum actuation force not to exceed 500gf
