Abstract

A medium voltage operating-isolating switch with three positions insulated in sulphur hexafluoride comprising a set of three poles, each pole comprising a fixed contact (14) and a mobile contact (26), the fixed contact carrying an associated male arcing contact (17) and the mobile contact being arranged on a pivoted arm (25) rotatable between a first closed position in engagement with the fixed contact, a second isolated position and a third earthed position. The mobile and fixed contacts of the set of three poles are arranged on three insulating base support elements (11) fixed to a single support beam (12), a relative cylinder (13) which pumps the sulphur hexafluoride into the insulating nozzle (15) being associated via an insulated lever with each of the arms carrying the mobile contacts, a metal draining element (44) being provided between each of the insulating support elements and the pumping cylinders.
