金航标KH-6X6X4.3H-STM SMD轻触开关产品概述

金航标(Kinghelm)KH-6X6X4.3H-STM是一款6×6mm规格的立贴式(SMD)轻触开关,采用单刀单掷(SPST)电路结构,专为低压小电流控制场景设计,兼具小尺寸、高可靠性与易安装性,广泛适配消费电子、智能家居等领域的高密度PCB布局需求。

一、产品核心定位与典型应用

该开关属于小型化SMD轻触开关,核心定位为低压小电流场景下的高频操作控制元件,重点满足设备对“紧凑空间+可靠触发”的双重需求。其典型应用场景包括:

  • 便携式电子设备:智能手环、蓝牙耳机、便携式充电宝等小型穿戴/手持设备的功能按键(如电源键、模式切换键);
  • 消费类电子:电视遥控器、空调遥控器、计算器、小型游戏机等日常高频使用的按键组件;
  • 智能家居设备:智能开关面板、智能门锁、传感器节点(如温湿度传感器)的配置按键;
  • 小型工业控制:小型PLC、传感器模块、工业遥控器等低功耗控制设备的操作按键。

二、关键参数与结构设计

2.1 基础规格参数

  • 尺寸:开关主体长×宽×高=6mm×6mm×4.3mm,属于6×6mm标准轻触开关规格,适配紧凑PCB布局;
  • 安装方式:立贴式(SMD),无支架设计,进一步节省安装空间;
  • 引脚样式:鸥翼型引脚,符合SMD回流焊工艺要求,焊接可靠性高;
  • 按钮设计:圆形按钮,黑色盖帽,耐脏且视觉辨识度清晰。

2.2 电气性能参数

  • 触点电流:50mA(直流),满足低压小电流控制需求;
  • 额定电压:12V(直流),适用于常见低压电路(如5V、12V供电系统);
  • 电路结构:单刀单掷(SPST),即“常开”型,触发时闭合,释放时断开,符合大多数轻触开关的功能需求。

2.3 结构设计优势

  • 紧凑无支架:不带支架设计减少了安装占用空间,同时降低了整体重量,适合便携式设备;
  • 鸥翼引脚:相比直插引脚,鸥翼型引脚更适配表面贴装工艺,回流焊时不易出现虚焊,且抗振动性能较好;
  • 圆形按钮:按压手感舒适,触发行程稳定,减少误触概率。

三、安装与兼容性

该开关采用立贴SMD封装,适配主流电子设备的PCB设计:

  • 焊接工艺:支持标准回流焊、波峰焊(需适配立贴工艺),鸥翼引脚与PCB焊盘接触面积适中,焊接可靠性高;
  • 布局兼容性:6×6mm标准尺寸,可与同规格SMD元件并排布局,适合高密度PCB设计(如多层板、迷你型PCB);
  • 无支架设计:无需额外支架固定,直接贴装于PCB表面,简化安装流程,降低装配成本。

四、可靠性与耐用性

  • 工作寿命:额定8万次操作寿命,满足日常高频使用需求(如遥控器每天按压100次,可使用约2.2年);
  • 触点稳定性:50mA触点电流设计,避免大电流导致的触点烧蚀,保证长期使用中的接触可靠性;
  • 环境适应性:黑色按钮盖帽耐脏、抗常规环境紫外线,不易褪色;立贴结构抗振动性能较好,适合移动设备使用。

五、选型与使用注意事项

  1. 选型匹配:仅适用于直流50mA/12V以内的电路,禁止用于大电流(如超过100mA)或高压场景,否则会导致触点损坏;
  2. 安装规范:回流焊温度需符合SMD元件标准(通常峰值温度≤260℃,回流时间≤30秒),避免高温损坏开关内部结构;
  3. 使用限制:禁止超过额定操作寿命使用,避免长期按压导致弹簧疲劳失效;
  4. 清洁要求:安装前需保持PCB表面清洁,避免焊锡残渣或灰尘影响焊接质量。

综上,金航标KH-6X6X4.3H-STM轻触开关凭借小尺寸、高可靠性、易安装等优势,成为低压小电流控制场景下的优选元件,广泛适配消费电子、智能家居等领域的多样化需求,是设计师实现紧凑空间内可靠按键控制的理想选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
