Electrical service switching device

Electrical service switching device, such as a circuit breaker, having a magnetic release with a magnet armature, a thermal release, a fixed and moving contact piece, a switching mechanism which can be tripped by the thermal and magnetic release and has a latching point which is formed by a tripping lever and a catch lever which is mounted in a fixed position such that it can rotate and has an elongated hole in order to guide a clip, wherein the magnet armature can act on the contact lever, to which the moving contact piece is fitted, in order to open the contact point in the event of a short, and the switching mechanism can hold the contact lever permanently in the open position, having a switching toggle for manual operation of the switching mechanism, and having an intermediate lever which is articulated at one of its ends with the contact lever and at its other end on the clip, wherein the clip is articulated with at least one limb on the switching toggle, wherein the contact lever forms a first assembly, which can be inserted in a prefabricated form into the housing of the service switching device and, after insertion into the housing, is mounted such that it can pivot on a rotation shaft which is connected to the housing at a fixed position, and wherein the switching toggle, together with the tripping lever, the catch lever, the intermediate lever and the clip forms a second assembly, which can be inserted in a prefabricated form into the housing and, after insertion, is connected in an articulated manner at a separation point to the first assembly.
