In this paper, the burn-out failure of contact of relay used in air-conditioner has been discussed. By ana-lyzing the material, size and construction of contact of relay, and considering the operating principle of relay, the failure causes have been investigated. It has been found that the thickness of contact plating and times of bounce have significant influences on the life of relay. In addition, the noise interference caused by bounce has an effect on the reli-ability of circuits. By means of controlling the size of contact and decreasing times of bounce can effectively improve the life of relay.
