金属复合触头产品具有以下特点：
①复合电触头焊接面为纯铁材料，并带有小凸点，以增加焊接性能，能使电触头与双金属片及不锈钢片等铁基合金焊接牢固。
②焊接部位是通过熔融金属接合，其电气稳定性优于铆接型触点而且定位性好，焊接美观，若采用铆接方法，铆接过紧造成双金属变形，铆接过松造成系统电阻增大，均将造成温控器的误差。
③与钎焊型触头相比，加热时间短，作业环境清洁，适合于微小部件接合加工，尤其适用微细机构场合使用。
对金属复合触头，可根据电器通过的电流大小，选择不同的银合金材料，适用于脉冲焊接方法与触桥联接，可制备电器接触零件及双金属触桥，广泛用于继电器、微型开关、温控器、按键、温度控制器和断路保护器中。
对金属复合触头产品的生产，现有扎机、挤压机、点焊机、自动冲压机、平片机、液压机、金相显微镜、硬度计、投影仪、工具显微镜等生产、检测设备 100台套，可根据用户的具体要求进行开发生产，已形成年产2亿粒的生产能力。
适用于脉冲焊接方法与触桥连接，广泛用于微型开关/温控器/按键和断路保护器中。
银触点有哪些功能？ 银触点的最大优点是增加了导体的使用频率，增加了接触效果，增强了导体的性能。银触点广泛用于电子电器的生产，如开关、继电器、温控器、导电电路中的交叉点支点等，主要用银点机铆接在各种配件的端子上。 所以我们生活中的很多东西都有银触点。银触点等原厂配件广泛应用于各种高低压电器、电子电器、翘板开关、电源开关、继电...
