Abstract
A disconnectable current tapping device is provided having clips engageable on onmibus bars and disengageable therefrom by translation of a clip carrying slide controlled by a rotary shaft, which is rotated by a plug which is mounted for translation on the shaft while being urged by a return spring, and which is subjected to the action of a control member such as an operating key. By an axial thrust exerted on the plug, a transmission piece provided with a spur in engagement in an annular groove formed in the plug, is drawn in translation so as to actuate a prebreak microcontact; at the end of rotation of the shaft controlling the disconnection, the piece is retained by a resilient retractable member, whereas the plug is returned only through a ramp provided at the edge of the groove so as to allow release of the spur.
