A circuit breaker with a first contact sleeve ( 3, 14 ), a second contact sleeve ( 4, 16 ), an insulating sleeve ( 5, 18 ) disposed between the first contact sleeve ( 3, 14 ) and the second contact sleeve ( 4, 16 ) has a switching piston ( 6, 20 ) with at least one contact section ( 8 ) and an isolating section ( 7, 19 ), which is disposed at the side of the contact section ( 8 ), whereby the switching piston ( 6, 20 ) is movable between a closed position in which the contact section ( 8 ) of switching piston ( 6, 20 ) connects the first contact sleeve ( 3, 14 ) with the second contact sleeve ( 4, 16 ) so as to be electrically conductive, and an open position in which the contact section ( 8 ) of the switching piston ( 6, 20 ) does not connect the first contact sleeve ( 3, 14 ) with the second contact sleeve ( 4, 16 ), in which the first contact sleeve ( 3, 14 ), second contact sleeve ( 4, 16 ) and insulating sleeve ( 5, 18 ) is movable. The isolating section ( 7, 19 ) is elastically deformable and in the insulating sleeve ( 5, 18 ) exerts a surface pressure force on the surface thereof due to elastic deformation. The circuit breaker according to the invention is reclosable.
