In the wave of miniaturization and intelligent development of electronic devices, tactile switches, as core components of human-machine interaction, directly impact the user experience of end products. The KH-12X12X6H-SMT tactile switch, launched by Shenzhen Kinghelm Electronics Co., Ltd., provides a high-precision, high-reliability solution for modern electronic designs with its compact 12×12×6mm dimensions and SMT (Surface Mount Technology) process.

Outstanding Electrical Performance and Mechanical Stability
The KH-12X12X6H-SMT adopts a single-circuit output design, with contact resistance strictly controlled below 100mΩ (tested at 1kHz/50mA), ensuring efficient and stable signal transmission. Its insulation resistance reaches 100MΩ (tested at DC250V), and its withstand voltage performance can endure harsh conditions of AC250V/1mA, effectively preventing breakdown risks. In terms of mechanical performance, the switch's actuation force is adjustable from 160±30gf to 260±50gf, while the precise 0.40±0.1mm travel distance, combined with a tactile feedback value of 30%-70%, provides users with clear haptic feedback, making it suitable for high-frequency operation scenarios.

Industrial-Grade Environmental Adaptability
This product has passed wide-temperature storage certification from -40℃ to 85℃, with an operational temperature range covering -20℃ to 70℃. In salt spray tests (5% concentration, 35℃, 4-hour cycles), it maintains a contact resistance of ≤200mΩ, meeting the requirements of coastal or high-humidity environments. It has also undergone 96-hour extreme tests under high temperature (80℃), high humidity (60℃/95% RH), and low temperature (-40℃), as well as five thermal shock cycles from -40℃ to 85℃, verifying its stability under extreme conditions.

Automated Production and Eco-Friendly Compliance
The KH-12X12X6H-SMT is optimized for SMT processes, supporting reflow soldering at 260℃±5℃ (3 seconds) and hand soldering at 350℃±5℃. Terminal strength tests show no mechanical damage under a 300g static load for 1 minute, ensuring high yield rates in PCB assembly. The product complies with RoHS standards and uses a PPA button combined with an iron cover plate, balancing durability and environmental requirements.

100,000-Cycle Lifespan Validation and Versatile Applications
After 100,000 no-load lifespan tests (100-120 cycles per minute), the switch's contact resistance remains below 200mΩ, with actuation force variation not exceeding 30% of the initial value. This characteristic makes it widely applicable in household appliances (microwave ovens, rice cookers), consumer electronics (TV control panels), and industrial equipment control modules, establishing it as the preferred component for engineers seeking reliable control in compact spaces.

Kinghelm KH-12X12X6H-SMT Specification

Backed by Kinghelm Electronics' rigorous quality control system (each batch undergoes 12 tests including withstand voltage, insulation, and salt spray) and 20 years of electronic component R&D experience, the KH-12X12X6H-SMT receives full lifecycle technical support. This product not only represents a technological benchmark for surface-mount switches but also sets a new standard for the miniaturization and durability of smart devices.
