Patent
CA 2018344
A contact device is provided with an additional mass member secured to a movable contactor carrying a movable contact capable of opening and closing contacts with a stationary contact, for providing to the movable contactor a mass acting in a direction perpendicular to longitudinal axis of the contactor. A rolling motion is thereby caused to occur in the movable contactor upon contact closing motion so that the movable contact can be prevented from being fusion-bonded to the stationary contact.
