| Abstract: | Surface hardness, contact resistance, adhesion force and electric arc energy are all important parameters that can represent the electrical contact behavior of contact materials used in electrical apparatus. In order .to investigate the failure mechanism of MEMS switch, a new test equipment for measuring electrical contact behaviors of contact materials with super slow velocity by introducing piezo motor was designed. The contact force characteristics ,hysteretic characteristics, contact voltage characteristics and arc characteristics of typical contact materials under loading and unloading process were observed and discussed. |
