摘　　要：介绍了一种研究电触头电寿命的实验方法 ,由实验结果分析比较了五种触头材料对称和非对称配对时的电寿命 ,并得到了有意义的结论。另外 ,实验后的触头表面大部分出现了裂纹 。This paper introduces a test method studying the electrical life of electrical contact first,then by experimental results the electrical life of five kinds of contact materials are analyzed and compared when they are symmetrically matched and asymmetrically matched,and some meaningful conclusions are reached.In addition,cracks appear on the surfaces of contacts after experiments,which illustrates the resistivity of the materials against cracks is weak.
