金航标KH-4.5X4.5X5H-STM轻触开关产品概述

一、产品基本定位

KH-4.5X4.5X5H-STM是金航标(Kinghelm)针对超小型电子设备推出的一款SMD立贴轻触开关,核心为单刀单掷(SPST)电路结构,聚焦“小空间、高可靠、易集成”需求,广泛适配便携式、薄型设备的功能触发场景。

二、核心参数与规格解析

该产品参数精准匹配小型化应用痛点,关键信息如下:

  1. 电路功能:单刀单掷(SPST),默认常开状态,按下时实现单路通断切换,适用于电源开关、模式切换等基础触发需求;
  2. 尺寸规格:长宽均为4.5mm,高度5mm, footprint仅4.5×4.5mm,是轻触开关中的超小型封装,可节省30%以上PCB空间;
  3. 安装方式:立贴(SMD)+ 鸥翼型引脚,兼容主流回流焊工艺,焊接时引脚与PCB贴合紧密,虚焊率低于0.1%;
  4. 外观细节:圆形黑色按钮(无额外盖帽突出),不带支架设计,进一步压缩整体高度至5mm,适配0.5cm以内的超薄设备;
  5. 品牌与合规:Kinghelm(金航标)原厂封装,符合RoHS环保标准,满足出口及绿色制造要求。

三、结构设计与工艺优势

  1. 鸥翼引脚可靠性:引脚采用鸥翼式折弯,回流焊时应力分散均匀,避免焊接变形;SMD立贴无需插件孔,简化PCB设计,提升生产效率;
  2. 圆形按钮触感优化:按钮为圆形凸起设计,操作时触感圆润,回弹力度适中(1-2N),减少误触概率,适合频繁操作场景(如手环模式切换);
  3. 触点寿命保障:内部采用银合金触点,抗氧化性能强,触点寿命可达10万次以上,满足便携式设备3年以上使用需求;
  4. 无支架轻量化:不带支架减少额外占用空间,产品重量仅0.1g左右,适配智能手环、蓝牙耳机等轻量设备。

四、典型应用场景

KH-4.5X4.5X5H-STM的超小型化特性使其成为以下场景的优选:

  1. 便携式消费电子:智能手环(功能切换键)、TWS耳机充电盒(配对键)、蓝牙耳机(电源键);
  2. 小型家电与遥控器:迷你电视遥控器(频道切换)、智能音箱(音量调节)、小型加湿器(模式键);
  3. 工业/车载微型模块:传感器节点(触发采集)、车载氛围灯控制器(模式切换)、微型PLC辅助键;
  4. 穿戴设备:智能手表侧键(功能唤醒)、运动手环模式键。

五、产品价值与市场适配性

  1. 空间适配性:4.5×4.5mm最小 footprint,解决超薄设备“无空间放开关”痛点(如厚度仅6mm的智能手环);
  2. 生产兼容性:SMD立贴+鸥翼引脚,可融入自动化SMT生产线,单台贴片机每小时可贴装10万+个,降低人工成本;
  3. 品牌可靠性:金航标作为国内电子元器件头部品牌,产品一致性好,批量采购良率达99.8%;
  4. 成本效益:性价比高于进口同类产品(如欧姆龙同类产品的60%价格),适合中低端便携式设备批量采购。

该产品以“小尺寸、高可靠、易集成”为核心竞争力,已成为国内便携式电子领域的主流轻触开关选型之一。

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
