    • A circuit protection device including a housing, a metal oxide varistor disposed within said housing, a terminal having a contact lead at a first end electrically attached to said metal oxide varistor by solder and having a second end extending outside of said housing, an arc shield disposed within said housing between said contact lead and said metal oxide varistor, a micro switch housed in a pocket portion of the housing, said micro switch having a trigger portion and an indicator portion disposed at least partially outside of said housing, said arc shield positioned against said trigger portion, and a spring configured to bias said arc shield away from said pocket portion and to move said arc shield away from said trigger portion when said solder is melted to provide a barrier between said metal oxide varistor and said contact lead, whereby the indicator portion is retracted into the housing.
    • 一种电路保护装置,包括壳体,设置在所述壳体内的金属氧化物变阻器,具有在第一端处的接触引线的端子,所述第一端通过焊料电连接到所述金属氧化物变阻器,并且具有延伸到所述壳体外部的第二端, 设置在所述壳体内的所述接触引线和所述金属氧化物变阻器之间,微型开关,其容纳在所述壳体的凹部中,所述微型开关具有触发部分和至少部分地设置在所述壳体外部的指示器部分, 以及弹簧,其构造成在所述焊料熔化时使所述电弧罩偏离所述袋部,并使所述电弧护罩远离所述触发器部分移动,以在所述金属氧化物变阻器和所述接触引线之间提供阻挡层,由此 指示器部分缩回到壳体中。
