The relay used is gradually increased. Because it is possible to easily control the high voltage and current. Bounce phenomenon is generated in contact during operation relay. As the result, arc is generated at the contact, thereby shortening the contact lifetime. In this study, we analyzed the bouncing phenomenon due to deterioration. It can be seen from the experimental results, and it is minimized at about 100,000 times. Bouncing phenomenon to increase again after the minimization. Consequently, the bouncing related to contact weight and shape of contact surface.
