Abstract
A miniature circuit breaker is disclosed with a latch for continuously opening and closing a contact point with a contact lever on which the moving contact member is molded. A toggle lever gear with a link connected to a switching handle and a coupling element are provided, the coupling element connecting the link with the contact lever, which toggle lever gear can be brought from a first stable position (switched-on position) into a second stable position via a dead-center position by a tripping mechanism. The contact lever can be rotated and the contact point can be permanently opened. A compression spring is provided which acts on the link, the force of which acts approximately in a direction of the longitudinal extent of the link in the switched-off position, and thus at the beginning of the switching-on process, and transversely thereto in the switched-on position.
