摘要 A current limiting switch is provided comprising two mobile levers subjected to the action of springs which apply, one against the other, separable contact pieces placed at the respective ends thereof; a thin electrically insulating screen placed between the levers so that its edge is inserted between the contact pieces while maintaining complete insulation between the levers when these latter move away from each other, following short circuit currents flowing in the switch, wherein the ends of the levers, where the contact pieces are placed, are situated in the immediate vicinity of an insulating surface of the case, so that the path of the arc is essentially tangential with respect to the movement of the mobile contacts, the movement of said edge towards and against said insulating surface causing constriction of the arc and completely insulating from one another the two opposite and sealed chambers which the screen separates within the internal volume of the case.
