It is expected that "chatter-vibration" of the switching relay may be reduced, if a damping force is applied to the relay spring. The present paper describes the result of an experiment, in which the free end of a cantilever under a damping force was collided with a rigid wall and the relation between the number of "make and break" and the damping coefficient was empirically determined. In order to apply the damping force to the cantilever, the principle that the Joule loss is caused by the electromotive force, which is induced by the vibration of the cantilever due to the magnetic field applied perpendicularly to the direction of vibration, was utilized. The result of theoretical analysis of the frequency response of the vibrating system is also described in the present paper. As a result, it has been clarified that the number of "make and break" markedly varies depending on the damping force applied to the relay spring.
