Patent ID: 7579933

Claim:
An electrical service switching device, comprising: a switching mechanism with a latching point which can be unlatched manually by a switching toggle or by an electromagnetic or thermal release the switching toggle including a switching handle; a tripping lever operable by the electromagnetic or thermal release, the tripping lever interacting with a rotatable latching lever which forms one element of the latching point; and a movable contact lever, which pivots, is acted on by the electromagnetic or thermal release in the event of a short-circuit and is moved to a disconnected position by the switching mechanism in the event of a short-circuit or overcurrent; wherein the latching lever together with the tripping lever forms the latching point, the tripping lever is mounted such that it rotates on the same rotation axis as the switching toggle, a projection which holds a first limb of a U-bracket is integrally formed on the switching toggle, opposite the switching handle, and a second limb of the U-bracket is guided such that it can move in an elongated hole in the latching lever and is connected in an articulated manner to a connecting lug, whose other end is connected to the contact lever, and wherein the latching lever runs approximately parallel to the connecting lug and alongside it, the connecting lug together with the latching lever forming an obtuse angle which is open in the direction of a front face of the switching device, only in a connected state, and the connecting lug being moved approximately parallel to the latching lever and approximately parallel to the front face in the direction of the latching point during a disconnection switching operation.
