  • 外形尺寸:长度4.5mm、宽度4.5mm、高度8mm(含按钮)
  • 安装方式:立贴式(SMD)
  • 结构配件:不带支架,圆形黑色按钮/盖帽
  • 引脚样式:鸥翼型
  • 品牌:kinghelm(金航标)
  • 封装类型:SMD

2. 性能补充参数(行业通用关键项)

  • 接触电阻:≤50mΩ(初始值)
  • 绝缘电阻:≥100MΩ(DC500V)
  • 额定电压电流:DC12V/50mA(最大)
  • 电气寿命:≥10万次按压
  • 工作温度:-20℃~+70℃
  • 储存温度:-30℃~+85℃

三、结构设计解析

1. 迷你尺寸适配空间限制

4.5×4.5mm的平面尺寸+8mm总高度,属于同类产品中的紧凑规格,可完美嵌入蓝牙耳机、智能手环、小型遥控器等设备内部,有效节省PCB布局空间。

2. 立贴+鸥翼引脚优化生产

  • 立贴SMD封装:无需手工焊接,直接适配自动化回流焊生产线,提升量产效率;
  • 鸥翼型引脚:宽间距设计便于贴装对位,降低虚焊风险,同时兼容常规贴装设备。

3. 实用化按钮设计

圆形黑色按钮符合人体工学,按压手感清晰无卡顿;不带支架简化安装流程,减少配件损耗与设备重量,降低成本。

四、核心性能特点

1. 高可靠接触性能

内部触点采用优质导电合金,多次按压后无明显氧化磨损,接触电阻稳定,确保信号传输准确。

2. 宽温环境适应性

-20℃~+70℃的工作温度范围,可满足不同地域、季节的设备使用需求,低温环境下仍保持正常响应。

3. 操作手感稳定一致

按钮行程与按压力度经过优化,每次按压反馈均匀,避免误触或失效,提升用户体验。

4. 环保合规

符合RoHS、REACH等环保标准,无有害物质,适配绿色制造需求。

五、典型应用场景

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
