Abstract

A switch suitable for DC applications includes: two fixed conductive contacts with first contact areas; a movable conductive bridge with two second contact areas for being connected to the two first contact areas in the on-status and for being disconnected from the two the first contact areas in the off-status; and two arc-extinguishing units configured to extinguish electric arcs occurring between the first and second contact areas after disconnecting the second contact areas from the first contact areas. First conductive arc-guiding elements extend from each first contact area into the corresponding arc-extinguishing unit and at least one second conductive arc-guiding element extends into the arc-extinguishing units suitably shaped to guide the electric arcs from each of the second contact areas of the movable bridge into the arc-extinguishing units.
