ABSTRACT:
The present invention relates to a device for fixing a shield in a switch, said switch being housed in an enclosure comprising a cylindrical part closed by two end parts forming covers, said cylindrical part being connected at its two free ends respectively to the two end covers and comprising one or more cylindrical insulators mechanically connected to one another, at least one shield for protection of the insulators being supported by a cylindrical ring fixed between two of the above-mentioned mechanically connected parts of the enclosure, at the level of the mechanical connection between these two parts. This device is characterized in that the above-mentioned shield comprises on its external surface at least one localized material spinning point, arranged in such a way as to form at least one bearing point of the shield on the ring, so as to achieve stopping of the shield in translation in a direction parallel to the axis of the enclosure.
