Abstract: Improvements in a quick-break attachment, for a pole-top air-break switch, wherein said attachment is of the type including a whip engaged in a catch to maintain a protective, anti-arcing shunt across the switch until the latter opens, whereupon the whip disengages and quick-breaks from the catch; the improvements consisting of instrumentalities which, firstly, assure of substantial acceleration in speed of the whip after its disengagement but before actual electrical separation occurs, and, secondly, prevent rebound of the disengaged whip into arcing contact with the catch.
