3JWD-DBHD-13.5 125 微动开关产品概述
一、产品核心定位与应用场景
3JWD-DBHD-13.5 125是SHOU HAN（首韩）品牌推出的微型单刀双掷微动开关，主打“紧凑尺寸+高可靠性”，精准适配对空间敏感、需频繁操作的小功率电子场景。其核心应用覆盖三大领域：
- 消费电子与智能家居：遥控器功能按键、门窗传感器触发开关、小型智能家电（如加湿器、香薰机）的模式切换；
- 工业控制终端：小型继电器辅助控制、传感器信号切换、微型操作面板的按键触发；
- 医疗辅助设备：便携式医疗仪器（血糖仪、雾化器）的操作按钮、小型监护设备的状态切换。
二、关键性能参数详解
该开关的参数兼顾“小体积”与“实用性能”，核心指标清晰明确：
- 寿命表现：带载电气寿命达5万次（额定电流下持续通断次数），空载机械寿命高达100万次，满足长期频繁操作需求；
- 电气参数：DC额定电流100mA、额定电压125V，适配5V/12V等小功率直流控制回路；
- 电路结构：单刀双掷（SPDT）设计，支持“常开-公共-常闭”三路引脚切换，灵活适配不同电路逻辑；
- 尺寸规格：开关主体长12.8mm、宽5.7-5.8mm（测量误差）、高6.6mm，柄长13.5mm，可嵌入10mm²级别的设备内部空间。
三、结构设计特点
- 微型封装与触发适配：采用PC插件引脚，间距适配常规PCB板布局；13.5mm柄长兼顾“操作便捷性”与“安装深度适配性”，可匹配不同设备的内部结构；
- 微动开关核心特性：触发行程小、响应灵敏，操作力适中（常规1-3N），避免误触发同时确保手感清晰；
- 引脚可靠性设计：PC引脚表面做防氧化涂层，提升焊接可靠性，减少虚焊风险。
四、环境适应性与可靠性
该开关的环境耐受性满足多数常规场景需求：
- 温度范围：工作温度覆盖-25℃~+85℃，可适应北方冬季低温（室内/户外短时间）、南方夏季高温，以及工业现场的温度波动；
- 触点性能：内部采用银合金触点，接触电阻小（常规<50mΩ），减少弱信号衰减，适配传感器等信号电路；
- 结构耐用性：工程塑料外壳+金属触点组合，避免长期操作导致的变形或触点磨损。
五、安装与使用注意事项
- 焊接适配：插件式引脚适合手工焊接或波峰焊，焊接温度建议≤260℃（持续时间<3秒），避免高温损坏内部触点；
- 空间预留：安装时在开关周围预留1-2mm间隙，便于散热与操作柄灵活运动；
- 过载防护：禁止超过100mA（电流）、125V（电压）使用，避免触点烧蚀或寿命缩短；
- 清洁维护：避免粉尘、油污进入内部，若出现接触不良，可用压缩空气轻吹清理。
总结：3JWD-DBHD-13.5 125微动开关以“小尺寸、高寿命、灵活切换”为核心优势，适配多场景小功率控制需求，是小型电子设备升级或定制的实用选择。

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.
