Abstract
The arc extinguishing unit of the switch comprises a body of insulating material (20) and two packs (21, 21') of superposed laminae (23, 23') insulated from one another. Each pack of laminae has an arc splitting side and a gas discharge side, and is arranged beside the other with the interposition of a substantially flat portion (28) of the body. In order to obtain compactness, efficiency of extinguishing of the arc, and discharge of the gases without dispersions within the switch, means (31-34) are provided for channelling the gases formed, partly inside the body (20) and partly by conjugate surfaces of the body and of at least one of the shells (5, 5') which together constitute the housing of the switch. Said channelling means extend from a region adjacent to the discharge side of each of the two packs of laminae as far as apertures (15) provided on one side of the housing. <IMAGE>
