Abstract
A finless current limiting switch apparatus is disclosed, in which the cut-off chamber, containing a fixed contact and mobile contact, has opposite converging walls which lead to a narrow slit where the arc is subjected to narrowing of its section after natural or assisted development thereof along a conducting deflection piece which is connected to the fixed contact and has an end located in the slit or in the vicinity of the slit. The conducting deflecting piece defines a conductive path of movement for the arc.
