Abstract
The disclosure relates to an electrical installation switching device, having a switching mechanism with a latching point which can be unlatched manually by means of a switching toggle or by means of an electromagnetic or thermal release, having a tripping lever which can be operated by the electromagnetic and thermal release and acts on the latching point, having a latching lever which forms one element of the latching point, and having a movable contact lever, which can pivot, is acted on by the electrical release in the event of a short-circuit and is moved permanently to the disconnected position by the switching mechanism in the event of a short-circuit or overcurrent. The latching lever (which is mounted in the enclosure such that it can rotate) together with the tripping lever forms the latching point. The tripping lever is mounted such that it can rotate 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, diametrically opposite the switching handle, and its other, second limb is guided such that it can move in an elongated hole in the elongated latching lever and is connected in an articulated manner to a connecting lug, whose other end is connected to the contact lever, which is mounted such that it can rotate.
