TS2306A 320GF SX 8R轻触开关产品概述

一、产品核心定位与典型应用场景

TS2306A 320GF SX 8R是SHOU HAN(首韩)品牌推出的一款小型化SMD立贴轻触开关,定位于低压小电流信号控制场景下的高可靠性基础开关,核心优势在于紧凑尺寸、稳定操作手感与批量生产适配性。

其典型应用覆盖三大领域:

  1. 便携式消费电子:智能手环、蓝牙耳机的功能切换键(配对/模式切换)、移动电源的电量显示键、MP3播放器的播放控制键;
  2. 小型工控与家电面板:智能家居控制器(如温湿度传感器、智能插座)的设置键、小型家电(如加湿器、台灯)的功能调节键;
  3. 车载微型部件:车载USB充电器的状态切换键、车内氛围灯的控制辅助键(适配车载常规温度范围)。

二、基础规格参数详解

TS2306A 320GF SX 8R的参数设计围绕“小型化+可靠性”核心,关键参数如下:

1. 电路与操作特性

  • 电路结构:单刀单掷(SPST),仅提供“通/断”两种状态,结构简单无冗余,故障概率低;
  • 按钮形态:圆形按钮,直径适配小型PCB布局,操作面积均匀,触感无死角;
  • 操作作用力:3.2N(±0.3N),经人体工学优化——既避免口袋碰撞等误触发,又不会因力度过大造成长时间操作疲劳。

2. 尺寸与封装

  • 封装类型:SMD立贴封装,适配自动化贴片生产线,焊接效率是插件式的2-3倍;
  • 核心尺寸:开关长度3.3mm、高度0.6mm(行业同类产品中属于紧凑级),宽度约2.5mm,可实现PCB高密度布局(1cm²内可容纳10+个开关);
  • 引脚样式:SMD接片式引脚,焊接面积大,回流焊后虚焊率低于0.1%(SHOU HAN工艺标准)。

3. 电气与环境性能

  • 电气参数:触点电流50mA(DC)、额定电压12V(DC),仅适用于低压信号控制(严禁用于大电流负载,如超过100mA的直流电机、继电器线圈);
  • 工作温度:-20℃~+70℃,覆盖我国大部分地区的室内外常规环境(如冬季北方室内、夏季南方户外);
  • 寿命与功耗:工作寿命30万次(无负载测试),按每日按压100次计算可稳定使用8年以上;无灯设计降低0.5mA静态功耗,适合电池供电设备。

三、结构设计与工艺特点

TS2306A 320GF SX 8R的结构针对“小型化+稳定性”做了针对性优化:

  1. 回弹结构:内置弹簧片设计,回弹速度≤0.1s,操作响应及时,无卡顿;
  2. 触点材料:银合金镀层触点,初始接触电阻≤50mΩ,镀层厚度≥2μm,长期使用无明显氧化;
  3. 外壳防护:耐高温ABS塑料外壳,可承受回流焊260℃峰值温度(10s以内),无变形;
  4. 防误触设计:按钮高出外壳0.2mm,避免PCB表面元件遮挡,同时防止误触。

四、安装与使用注意事项

为保障开关性能与寿命,需注意以下要点:

  1. 焊接要求:采用回流焊工艺,温度曲线需符合:预热区150-180℃(60s)、回流区220-260℃(10s)、冷却区≤100℃(30s);禁止手工烙铁直接焊接(易损坏外壳);
  2. PCB布局:引脚焊盘需预留0.5mm以上间距,避免相邻元件短路;按钮正上方需留1mm以上空间,防止按压干涉;
  3. 负载限制:严格遵循50mA/12V电气参数,超负载会导致触点烧蚀、寿命骤降;
  4. 存储环境:存储温度0-35℃、湿度40%-60%,避免接触硫化物等腐蚀性气体,防止引脚氧化。

五、产品优势总结

TS2306A 320GF SX 8R相比同类小型轻触开关,核心优势体现在:

  • 尺寸紧凑:0.6mm高度适配超薄设备(如5mm厚度的智能手环);
  • 手感稳定:3.2N作用力一致性好,批量产品手感无差异;
  • 可靠性高:30万次寿命满足8年以上使用周期,银合金触点抗氧化;
  • 生产适配:SMD立贴封装适合自动化生产,降低人工成本。

该产品是小型电子设备中“信号控制+空间紧凑”需求的高性价比选择,尤其适合电池供电的便携式产品。

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
