The circuit-breaker (1) has a sliding contact (7) moveable over a contact path (5), and a bi-metal spring (3) pushing the sliding contact on the contact path. The sliding contact is arranged on an annular carrier (6), which has contact surfaces (8) on the contact path. The carrier is symmetrically formed, and the bi-metal spring is formed as a torsion spring. A thermal contact is provided between the bi-metal spring and the sliding contact, and the carrier is arranged parallel to a board (4), which is arranged in a housing in a rotationally fixed manner.
