    摘要: The present invention relates to an electric switch (1) for high currents, in particular with a high short circuit withstand performance in the kA-range. Electric switches of this type are known and in use, but the electrical contacts in these switches are liable to separate due to blow-off or induced electro-magnetic forces during the passage of high short circuit or fault currents. The present invention provides an electric switch (1) that maintains a high mechanical contact force (F) but requires a lower mechanical force to open and close the switch and vice-versa.
