EVPAVAA1A 产品概述
一、产品简介
EVPAVAA1A 为松下（PANASONIC）微型触觉开关（Microswitch TACT），单刀单掷（SPST）结构，圆形按键，卧贴式表面贴装封装（SMD），黑色按帽。该器件以小体积、可靠触感和长期寿命为设计目标，适用于对体积、手感和耐久性有严格要求的便携及消费类电子产品。
二、主要参数
- 开关类型：单刀单掷（SPST），触点数：1
- 额定电流/电压：0.02A / 15VDC（信号级）
- 操作力：1.6 N（约合160 gf）
- 外形尺寸（封装）：2.8 × 2.65 × 1.95 mm（长×宽×高）
- 引脚样式：J型引脚（SMD）
- 安装方式：卧贴（无支架）
- 工作寿命：300,000 次操作
- 工作温度：-40 ℃ ~ +85 ℃
- 按钮颜色：黑色
三、结构与封装特点
EVPAVAA1A 采用超小 SMD 封装，J 形引脚便于回流焊接与 PCB 固定。无支架设计减小占位面积，适合高密度布局。圆形按键提供明确的触觉反馈，1.6N 的动作力在便携设备上兼顾误触防护与用户体验。
四、典型应用场景
- 移动终端按键、遥控器、蓝牙耳机控制键
- 可穿戴设备与健康监测终端的操作键
- 小型工业控制面板、仪表按键（信号级）
- 家电面板、消费电子产品的功能切换键
五、设计与焊接建议
- PCB 布局时为 J 形焊脚预留适当焊盘与通孔位置，建议参考厂商封装图纸以保证机械强度与焊点可靠性。
- 采用标准回流焊工艺，遵循松下推荐的温度曲线以避免过热影响寿命与触感。
- 由于额定为低电流信号开关，若用于更高电流或感性负载，需外接继电器或使用限流/保护电路。
- 在按键周围留出机械回流空间，避免遮挡按帽导致手感受限。
六、可靠性与环境适应
该开关在-40 ℃ 至 +85 ℃ 的温度范围内能稳定工作，额定寿命 30 万次，适合长期重复按压场景。触点电流限制（20mA）说明其更适合信号切换而非电源切换，使用时注意环境湿度与污染物对触点的影响。
七、使用注意事项与替代建议
- 避免超过额定电流与电压；如需更高功率，请选用额定更高的微动开关或机械继电器。
- 表面贴装后如需手工调整，请避免用力撬动引脚以免损伤内部机构。
- 若需要带支架或更大行程/不同按压力的型号，可参考松下其他 TACT 系列以匹配具体设计需求。
如需 PCB 尺寸图、回流曲线或 3D 模型，可提供更详细的技术资料以便布局与制造验证。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
