Abstract
An electric switch is provided using an isolating screen for destabilizing the arc. The pieces supporting the contacts are equipped with conducting extensions whose conformation and orientation allow the feet of the arc to circulate there without becoming stationary or coming back towards the contacts when the end of the screen moves towards a slot which receives it and when the mobile support effects an appropriate travel.
