Improved electrical connection device, of the type composed of an insulating box, internally provided with mobile contact lamellae that come into contact with other fixed according to the drive received from cams set on a fundamental axis of control, essentially characterized in that said lamellae movable contacts are elastic and are riveted rigidly on their outgoing terminals to the outside, and each of them has two intermediate angular appendices and directed in opposite directions to receive indistinctly the action of two cams that, stacked superimposed on the fundamental axis, have three differentiated diameters to obtain as many absolute positions of each mobile contact, capable of being combined with those of the other mobile contact to obtain a plurality of connection states with respect to the two pairs of fixed contacts faced with those mobile, including intermediate positions.
