KH-2435-CAJ是Kinghelm(金航标)推出的超小型卧贴式单刀单掷轻触开关,专为对尺寸空间、自动化生产适配性要求高的电子设备设计。产品聚焦“小型化+稳定安装+低功耗控制”核心需求,填补了超薄设备中紧凑操作键的选型空白,广泛适配消费电子、工控仪器等领域的小型化场景。
产品参数围绕“紧凑设计+可靠性能”展开,核心参数及应用价值如下:
参数类别 具体参数 应用价值 电路结构 单刀单掷(SPST) 实现“通/断”基础控制,满足单功能键切换需求 尺寸规格 长4.6mm×宽1.8mm×高3.5mm 超小型化,适配智能手环、蓝牙耳机等厚度≤4mm的超薄设备 电气参数 触点电流50mA、额定电压12V 满足低功率电路控制(如传感器触发、设备状态切换),避免过载风险 工作温度 -20℃~+70℃ 覆盖常规室内外环境(如车载常温、室内电子设备),稳定性可靠 结构细节 带支架、矩形黑色按钮 支架固定焊接位置,按钮操作手感清晰,黑色外观适配多数设备配色 封装/引脚 SMD接片引脚、表面贴装 适配回流焊自动化生产,提高贴装效率,降低人工成本产品结构针对小型化设备的痛点优化,核心优势体现在:
传统轻触开关多为立贴,占用PCB垂直空间;KH-2435-CAJ采用卧贴式布局,仅需3.5mm高度,同时搭配金属支架,焊接时可固定开关位置,避免回流焊过程中偏移,生产良率较无支架款提升15%以上。
按钮采用1.8mm宽×2mm高的矩形设计,既保证指尖操作的清晰反馈(按压行程适中),又不额外增加设备尺寸,适合智能穿戴、小型遥控器等频繁操作的场景。
引脚采用SMD接片式设计,贴合回流焊工艺要求,可通过贴片机批量高速贴装,单台贴片机每小时可贴装超10万颗,大幅降低生产周期。
触点采用镀金工艺,在50mA低电流下接触电阻稳定(≤50mΩ),避免因接触不良导致的误触发,寿命可达10万次按压(符合行业标准)。
KH-2435-CAJ的参数与结构特性,使其适配以下核心场景:
Kinghelm(金航标)作为国内电子元器件领域的成熟品牌,KH-2435-CAJ具备以下品质优势:
KH-2435-CAJ轻触开关以“超小型卧贴+带支架稳定+自动化适配”为核心竞争力,精准匹配消费电子、工控等领域的小型化设备需求,是替代传统立贴开关、解决紧凑空间操作键选型的优选方案。其可靠的电气性能与成熟的工艺,为设备提供稳定的控制体验,同时降低生产与采购成本。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
