The invention relates to a short-circuit device for medium and high-voltage switching devices, in which at least one moving contact is moved onto a fixed contact by means of a propelling charge. In order to ensure that a higher dielectric strength is produced, it is proposed that the short-circuit device comprises two contacts connected in series, wherein a fixed and a moving contact are provided in each case, and that the first fixed contact contains a mechanical ignition device for the propelling charge of the second moving contact in such a way that when the first moving contact reaches the first fixed contact this mechanically ignites the propelling charge for the second moving contact at this point. |
