Abstract
An electrical wiring device includes dampening member placed in contact with a stationary contact. The dampening member absorbs and thus decreases at least a portion of the vibration that occurs in the stationary contact when it is impacted by a movable contact in the electrical wiring device. Thus, the noise associated with the impact is lessened. In certain exemplary embodiments, the dampening member is a bumper cap which partially encases a portion of the stationary contact. In certain exemplary embodiments, the dampening member is a bumper pad intimately disposed between an edge of the stationary contact and a wall of the housing, such that movement or vibration of the stationary contact is lessened.
