Abstract:
1. An electrical service switching device comprising: a housing including a separation point having a first end and a second end; a rotation shaft arranged in the housing at a fixed position; a first assembly configured to be arranged in the housing at the first end of the separation point, the first assembly including a contact lever configured to pivot on the rotation shaft; a second assembly configured to be arranged in the housing at the second end of the separation point independently of the first assembly, the second assembly including a switching toggle, a tripping lever, a catch lever, an intermediate lever, and a clip; a fixed contact piece; a moving contact piece arranged on the contact lever; a magnetic release including a magnet armature configured to act on the contact lever to separate the fixed contact piece from the moving contact piece during a magnetic tripping; and a thermal release configured to separate the fixed contact piece from the moving contact piece during a thermal tripping, wherein the tripping lever and the catch lever are configured to separate when the moving contact piece is separated from the fixed contact piece and latch together when the moving contact piece is connected to the fixed contact piece, wherein the catch lever includes an elongated hole configured to guide the clip and is mounted in a fixed position such that the catch lever is configured for rotation, wherein the switching toggle is configured to enable manual connection of the moving contact piece to the fixed contact piece and enable manual separation of the moving contact piece from the fixed contact piece, wherein the intermediate lever includes a first end articulated with the contact lever and a second end articulated on the clip, wherein the switching toggle includes at least one limb articulated with the clip, wherein the separation point comprises a coupling point between the first end of the intermediate lever and a free end of the contact lever, wherein the clip includes two U-limbs so as to be approximately U-shaped, the U-limbs each including a respective free end, wherein the clip further includes a clip web which connects the two U-limbs, and guide projections which are integrally formed at the free ends of the U-limbs, wherein the clip web is configured to be guided for movement in the elongated hole in the catch lever, wherein the switching toggle includes a switching handle and two projections diametrically opposite the switching handle, wherein the projections are integrally arranged in the form of a fork having opposed projection surfaces and an accommodation area between the opposed projection surfaces, which is open on one side of the switching toggle, and wherein one of the guide projections of the clip is held so as to be pivotable in each of the two projections.
