KH-4.5X4.5X6.5H-SMT 轻触开关产品概述

KH-4.5X4.5X6.5H-SMT是金航标(Kinghelm)推出的一款微型贴片式轻触开关,专为空间受限的电子设备设计,凭借紧凑的4.5×4.5×6.5mm尺寸、稳定的SMD封装及可靠的性能,广泛适配消费电子、智能穿戴、小型家电等领域的按键控制需求。

一、产品核心规格参数

该型号轻触开关的基础参数清晰明确:

  • 物理尺寸:开关主体长×宽×高为4.5mm×4.5mm×6.5mm,属于微型方形封装,体积小巧;
  • 封装类型:SMD(表面贴装),支持自动化贴装生产,兼容无铅回流焊工艺;
  • 品牌与认证:金航标原厂出品,符合RoHS、REACH等环保标准,部分定制批次可提供UL/VDE认证;
  • 可选拓展参数:操作力提供160±20gf(轻触型)、260±20gf(重触型)两种规格,触点采用银合金材质,提升导电稳定性与耐磨寿命。

二、封装与尺寸设计优势

  1. 紧凑尺寸适配窄空间:4.5×4.5mm的方形底座占板面积仅20.25mm²,6.5mm的高度低于多数同规格开关,可嵌入智能手环、蓝牙耳机充电盒等超薄设备内部;
  2. SMD封装提升生产效率:贴片引脚采用标准间距设计(常规0.5mm或1.0mm),兼容主流贴片机,贴装精度高,减少人工焊接成本;
  3. 结构稳定性:底座采用耐高温PC/ABS合金塑料,引脚为黄铜镀锡,焊接牢固且抗腐蚀,避免长期使用后引脚脱落。

三、电气性能指标

该型号电气参数满足多数电子设备的控制需求:

  • 额定电压/电流:常规为DC 12V / 50mA,可定制DC 24V / 100mA规格;
  • 接触电阻:初始≤100mΩ,经10万次寿命测试后≤500mΩ,保证信号传输无延迟;
  • 绝缘电阻:≥100MΩ(DC 500V,1min),防止相邻引脚短路;
  • 耐电压性能:AC 250V(50Hz,1min)无击穿、无飞弧,适配低压控制电路。

四、机械性能特性

  1. 清晰操作手感:触发行程0.2±0.1mm,回弹时间≤10ms,按压时具有明确“咔嗒”声,避免误触;
  2. 长寿命设计:银合金触点配合不锈钢弹片,常规寿命10万次,定制高寿命版本可达50万次以上(适配高频操作);
  3. 抗机械应力:可承受10~500Hz振动(1.5mm振幅)及1000m/s²冲击(6ms),无功能失效,适配工业环境。

五、典型应用场景

因尺寸小巧、可靠性高,该型号适配以下场景:

  1. 智能穿戴:智能手环、手表的功能键(模式切换、心率监测),适配超薄机身;
  2. 小型家电:加湿器、空气净化器的电源/模式键,耐日常温湿度;
  3. 消费电子配件:蓝牙耳机充电盒、无线遥控器的配对键,满足便携需求;
  4. 医疗器械:小型血糖监测仪、雾化器的操作键,符合医疗设备可靠性要求;
  5. 工业控制:小型PLC、传感器的辅助设置键,抗振动性能适配工业环境。

六、使用注意事项

  1. 贴装工艺:遵循无铅回流焊曲线(峰值230~250℃,时间≤30s),避免过温导致底座变形;
  2. 清洗要求:用中性清洗剂清洗,避免腐蚀性溶剂,清洗后烘干(≤60℃);
  3. 存储条件:存于干燥通风环境(-30℃~+85℃,湿度≤60%),避免潮湿暴露;
  4. 选型匹配:高频操作选50万次寿命版本,敏感操作选160gf轻触型。

该型号轻触开关凭借金航标的成熟工艺与稳定性能,成为小型电子设备按键控制的优选方案,可根据客户需求定制操作力、寿命及认证规格。

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
