Abstract:
A burn-up switching arrangement, with a first switching piece which, in a switch-on position, is connected to a first electrical terminal and which comprises a contact bell with a plurality of contact fingers, and with a second switching piece which, in the switch-on position, is connected to a second electrical terminal and which comprises a switching pin which can be moved relative to the first switching piece, along a switching axis, between the switch-on position, in which the contact fingers of the contact bell touch the switching pin on its outside, so that the burn-up switching arrangement closes a current path between the first terminal and the second terminal, and a switch-off position, in which the switching pin is at a distance from the first switching piece, the contact fingers of the contact bell being connected to the first electrical terminal via a flexible lead which allows a change in an angle between a longitudinal axis of the contact fingers and the switching axis, and at least one supporting face being provided for supporting at least part of the flexible lead, wherein the at least one supporting face is formed by a continuous outside of a supporting body, in that the supporting body includes electrically insulating material at least in the at least one supporting face, and in that an inside of the supporting body is an insulating nozzle widening in the switch-on direction, said supporting body being positioned so as to prevent inward elastic action of the contact fingers toward the switching axis.
