Abstract

Switch comprising, for each pole, a blade-shaped double moving contact (24) cooperating under rotation with a plurality of stationary contacts (14 - 22) in order to occupy a first closing position in which the first and third stationary contacts (14, 18) are interconnected by the blade, a second opening position in which the blade engages with a fourth stationary contact (20), and a third position for earthing the exit cable (28) thanks to the interconnecting of the second and fifth stationary contacts (16, 22) by means of the blade. The second and third stationary contacts (16, 18) are permanently joined together by an electrical connection (32). The same is true for the fourth and fifth stationary contacts (20, 22), thanks to an earth connection. The moving contact (24) is associated with a metal shield (36) advantageously arranged as a guard ring in the second opening position. The presence of this shield ensures an isolating function making it possible to retain the isolation between the input and output terminals (26, 28). Application: electrical panel for a medium-voltage distribution station. <IMAGE>
