Abstract: Disclosed is a high-current switch comprising a first fixed contact, a second fixed contact spaced apart from the first fixed contact, and at least one contact bridge that is movable relative to the two fixed contacts and an advancing device for transferring the contact bridge from an open position, in which the two fixed contacts are not connected to one another, to a closed position, in which the contact bridge electrically connects the two fixed contacts to one another. The advancing device is configured such that it is non-resilient, the stiffness of the contact bridge and of the advancing device corresponding to a value of at least 50,000 kNmm2 in the direction of the pressing force, and the lowest natural frequency of the system, which consists of the contact bridge and the advancing device, being higher than 2,000 Hz in the direction of the pressing force.
