TS342A2P-WZ 产品概述
本产品为 SHOU HAN(首韩) 系列轻触开关 TS342A2P-WZ，属于表面贴装小型单刀单掷（SPST）轻触开关，常用于便携式电子设备的按键输入。外形小巧、结构可靠、触感明确，适合对空间和成本有较高要求的应用场景。
一、主要参数一览
- 产品型号：TS342A2P-WZ
- 结构形式：单刀单掷（SPST）
- 尺寸（长×宽×高）：3.9mm × 2.9mm × 2.0mm
- 按钮形状：圆形塑胶按钮（黑色）
- 安装方式：表面贴装（SMD）——两脚接片（两脚小龟，不带柱）
- 触点电流：50mA
- 额定电压：12V DC
- 操作力：2.5N（约250gf）
- 寿命：50,000 次（典型）
- 工作温度：-20℃ ~ +70℃
- 是否带灯：否
- 是否带支架：否
二、产品特点
- 极小封装：3.9×2.9×2.0mm 的超小体积，便于高密度布局和轻薄化设计。
- 稳定手感：250gf 的动作力提供明显触感回馈，适合常用按键场景。
- SMD 贴装：适合再流焊工艺，便于自动化贴装与批量生产。
- 长寿命与可靠性：50,000 次寿命满足多数消费类和工业类按键周期需求。
- 宽温适应：-20℃至+70℃的工作温度范围，支持常见室温与轻工业环境。
三、电气与机械性能
- 额定工作条件下的最大开关电流为 50mA，额定电压 12V DC，适用于低电压低电流信号开关场合（如按键扫描阵列、开机/复位等）。
- 机械尺寸与结构设计保证在有限行程内有明确的接触与断开动作，避免接触抖动对信号识别的影响。
四、典型应用场景
- 移动终端（遥控器、小型手持设备）
- 家电控制面板（小按键选项）
- 电子玩具、手持仪器
- 工业控制面板中的低电流信号输入
- 各类需要微型 SMD 触点的消费电子产品
五、使用与焊接建议
- 建议采用标准 SMD 贴装流程与 Pb-free 再流焊参数，严格控制回流曲线以保护塑料件和内部触点结构。
- 焊盘设计请参考厂方推荐 PCB 贴片尺寸，保证两脚接片充分焊锡覆盖且维持元件定位稳定。
- 焊接后建议进行功能检测（通断、接触电阻）与外观检查，确认无虚焊或移位。
- 在设计按键布局时预留足够的按压力分散空间，避免相邻元件受力或干涉。
六、存储与可靠性注意事项
- 建议在干燥、常温环境下存放，避免长时间暴露于潮湿或强腐蚀性气体环境。
- 防静电防冲击包装可延长出厂前储存可靠性。
- 在长期库存后进入生产前，建议先做外观与功能抽检。
七、包装与订购信息
- 封装形式：SMD 卷带包装，适配自动贴片机（请按需向供应商确认卷带单位长度与配带件）。
- 购买时请确认型号、批次与规格（尤其是操作力、引脚样式与是否带柱），以免因外形修改导致贴装不兼容。
如需详细的 PCB 推荐焊盘图、回流焊曲线或样品测试报告，可向供应商索取 TS342A2P-WZ 的产品资料与工程支持。若有具体应用电路或贴装工艺问题，也可提供进一步的现场建议。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
