摘要：A multiplicity of mobile contact levers 13 is thrust by the same contact pressure spring 21 against fixed contacts 24 placed at the end 72 of a contact rod 71 placed coaxially with the spring, and capable of moving axially in order to effect a controlled opening, whilst magnetisable means 31 associated with the levers assist in their automatic opening and an insulating case 79 is propelled rapidly between the contacts by virtue of the gas pressure developed in the presence of arcs, this case assuming, at the end of travel, a working position for which the required insulation is effected. <IMAGE>
