High-voltage switch with a first terminal contact connected to a first fixed contact, a second terminal contact connected to a second fixed contact, a bridge contact arranged between the first fixed contact and the second fixed contact and connecting the first fixed contact to the second fixed contact, the bridge contact being pressed against at least one of the fixed contacts with a contact pressing force and being able to be released from at least one of the fixed contacts with a pull-off force, and a drive acting on the bridge contact in the direction of the pull-off force. A measuring circuit senses a voltage drop between the fixed contacts in case of levitation between at least one fixed contact and the bridge contact and depending on the sensed voltage drop controls the drive in such a way that the drive acts on the bridge contact with a force in the direction of the pull-off force.
