Abstract

An electrical contact system includes a static contact having a static contact point, a movable contact having a movable contact point, a rotating member on which the movable contact is mounted, and an arc extinguishing device having an arc extinguishing sheet. The movable contact is rotatable with the rotating member between a switch-on position and a switch-off position. When the movable contact is rotated to the switch-on position, the arc extinguishing sheet is rotated beyond a contact area between the movable contact point and the static contact point, allowing electrical contact of the movable contact point with the static contact point. When the movable contact is rotated to the switch-off position, the arc extinguishing sheet is rotated into the contact area between the movable contact point and the static contact point, electrically isolating the movable contact point from the static contact point and cutting off an electric arc.
