DPL-03RP 产品概述

一、产品简介

DPL-03RP 为 XKB Connectivity(中国星坤)推出的一款 3 位琴键式开关,采用单刀单掷(SPST)电路结构,面向小型控制面板、音响设备、家用电器及工业仪表等需要明确位置切换的场合。该产品为插件式(through‑hole)封装,红色外观,适用于标准 2.54mm 网格的 PCB 布局,兼顾手感、可靠性与安装便捷性。

二、主要参数

  • 类型:琴键式开关(Piano/key style)
  • 电路结构:单刀单掷(SPST)
  • 开关位数:3 位(3-position)
  • 引脚样式:PC 引脚(适用于通孔焊接)
  • 脚间距(Pin pitch):2.54 mm
  • 额定电流:25 mA
  • 额定电压:24 V(DC)
  • 工作温度范围:-20 ℃ ~ +70 ℃
  • 工作寿命(机械):约 3,000 次切换
  • 颜色:红色
  • 品牌:XKB Connectivity(中国星坤)
  • 封装形式:插件(through‑hole)

三、结构与外形特点

DPL-03RP 采用典型的琴键(平板或凸起按键)机构设计,操作行程明确,三位切换对应三种不同的接通状态(例如:位置 1、位置 2、位置 3)。外壳与按键均采用耐用工程塑料成型,表面颜色为标准红色,便于在面板上识别和配色。引脚以 PC 引脚形式出线,适配直插式安装,方便波峰焊或手工焊接。

四、电气与机械特性

  • 电气性能:额定承载为 25 mA / 24 VDC,适合小电流信号控制与低压逻辑电路切换。
  • 机械寿命:结构寿命约 3,000 次切换,适用于周期性切换但不建议用于高频反复切换的重负载场合。
  • 环境适应性:工作温度范围 -20 ℃ 至 +70 ℃,可满足常见消费电子与部分工业环境的温度要求。
  • 接触与绝缘:为保证长期稳定性,建议在关键设计中参考供应商的接触材料和抗氧化处理方案(具体接触电阻、绝缘电阻、耐压值请以出厂规格书为准)。

五、PCB 布局与安装建议

  • 网格与孔位:产品引脚采用 2.54 mm 步距设计,便于与标准插接件、排针或面板开孔对接;PCB 布局时建议按厂方提供的尺寸图纸制作焊盘和孔位,以确保可靠插装与焊接。
  • 焊接方式:支持手工焊与波峰焊(插件封装);为避免热损伤,焊接工艺应遵循通用通孔元件的温度-时间限制并以供应商焊接指南为准。
  • 固定与支撑:在面板安装时建议结合定位孔或卡位使用,以减轻焊点应力并提高长期可靠性。按键所在区域应保持适当的开孔或凸台空间,避免干涉操作行程。
  • 去抖动处理:在电路设计层面,建议对开关输入信号做去抖(硬件 RC 滤波或软件去抖)处理,以确保数字电路的稳定响应。

六、典型应用场景

  • 家用电器的模式切换与功能选择(例如小型控制面板)
  • 音响、调音台与乐器设备的通道或功能切换
  • 小型仪器仪表与测试设备的面板控制
  • 消费类电子终端的用户输入与设置切换
  • 教育类或演示用设备的控制单元

七、可靠性与储存建议

  • 使用寿命与可靠性:机械寿命为约 3,000 次,适合中低频率的手动操作场合。
  • 工作环境:推荐在无腐蚀性气体、相对湿度受控的环境中长期使用。高温、高湿或酸碱环境会加速触点劣化与机械磨损。
  • 储存:存放时避免阳光直射与潮湿环境,长期储存前建议密封包装并放置于干燥、常温环境。

八、订购信息与注意事项

  • 型号示例:DPL-03RP(红色、3 位、单刀单掷、PC 引脚、2.54 mm 步距)
  • 品牌:XKB Connectivity(中国星坤)
  • 包装:插件(through‑hole)批量包装,具体包装数量与出货方式请咨询供应商。
  • 定制与测试:如需特殊颜色、延长寿命版本或详细电气参数(如接触电阻、绝缘电阻、耐压值等),建议联系供应商提供样品和详细规格书以作功能验证与可靠性测试。

DPL-03RP 以简洁的三位琴键结构与标准化 PCB 接脚布局为设计出发点,适合对空间、成本与可靠性有平衡需求的面板控制场合。在设计导入阶段建议参考厂方尺寸图与焊接指南,同时在样机阶段进行去抖、耐久与环境测试以确保产品长周期运行的稳定性。

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
