KH-4.5X4.5X6H-STM轻触开关产品概述

KH-4.5X4.5X6H-STM是金航标(kinghelm)推出的超小型立贴式单刀单掷轻触开关,针对紧凑空间内的操作控制需求设计,兼具小型化、高可靠性与易装配性,广泛适配消费电子、小型家电及物联网终端等场景。

一、产品核心定位与典型应用

该开关定位于微型设备的功能控制核心,以4.5×4.5×6mm的超小尺寸解决了便携/迷你设备的空间限制问题,同时通过立贴封装与SPST结构满足常规开关的动作需求。其典型应用场景包括:

  • 消费电子便携端:智能手环/手表的模式切换键、蓝牙耳机的音量调节键、迷你MP3的播放控制键;
  • 小型家电控制面板:电视迷你遥控器的频道/音量键、加湿器的启停/模式键、香薰机的定时调节键;
  • 工业物联网终端:温湿度传感器的校准触发键、微型PLC的辅助功能键、智能门锁的应急操作键。

二、关键参数与规格详解

(一)电路与功能结构

采用单刀单掷(SPST) 电路结构,动作逻辑为「按下导通→松开断开」,无自锁功能,符合常规轻触开关的操作习惯,可满足单次触发、脉冲控制等基础功能需求。

(二)安装与封装方式

  • 安装方式:立贴式(SMD立装),无需额外插件孔,直接贴合PCB表面;
  • 引脚样式:鸥翼型引脚,兼容常规SMT生产线(回流焊/波峰焊),焊接后牢固性强;
  • 支架设计:无支架,进一步压缩安装空间,简化装配流程。

(三)尺寸与外观参数

  • 整体尺寸:长4.5mm×宽4.5mm×高6mm(含按钮高度),属于超小型轻触开关范畴;
  • 按钮细节:圆形黑色按钮/盖帽,直径适配手指操作,视觉辨识度清晰,避免误触。

(四)电气与机械性能(行业常规参数补充,符合金航标同类产品标准)

  • 触点寿命:≥10万次(常温常压下);
  • 工作温度:-20℃~+70℃;
  • 接触电阻:≤50mΩ(初始状态);
  • 绝缘电阻:≥100MΩ(500V DC);
  • 额定电压/电流:12V DC/50mA(常规轻触开关标准)。

三、工艺特点与可靠性保障

  1. 触点工艺:采用银合金触点(部分批次镀金),降低接触电阻,提升耐磨损性,延长开关寿命;
  2. 结构稳定性:立贴式鸥翼引脚设计,焊接时与PCB贴合紧密,无支架情况下仍能保证机械强度,避免松动;
  3. 环境适应性:外壳采用耐高温工程塑料(如PBT),可承受SMT焊接温度(260℃以下3秒),同时耐轻度油污、灰尘,适合复杂应用场景;
  4. 一致性管控:金航标标准化生产流程确保每颗开关的尺寸、动作力度(常规1.5-2N)一致性,适配批量生产需求。

四、应用优势总结

  • 空间高效:4.5×4.5×6mm超小尺寸,适配便携设备的紧凑布局;
  • 装配便捷:立贴封装+鸥翼引脚,兼容SMT自动化生产,降低人工成本;
  • 可靠性强:银合金触点+工程塑料外壳,满足10万次以上寿命与宽温需求;
  • 操作舒适:圆形黑色按钮,手感适中,避免误触,提升用户体验。

五、选型与使用注意事项

  1. 选型确认:需确认PCB安装空间是否匹配4.5×4.5mm的占位面积,以及功能需求是否为SPST单动作;
  2. 焊接规范:焊接温度不超过260℃,焊接时间≤3秒,避免高温损坏外壳;
  3. 存储要求:存储于干燥通风环境(温度15-35℃,湿度40-60%),避免长期暴露于潮湿/高温环境;
  4. 操作限制:避免过度按压(超过5N),防止触点磨损或外壳变形。

以上为KH-4.5X4.5X6H-STM轻触开关的核心概述,可根据具体应用场景进一步确认参数匹配性。

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
