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