- This screed 123; 223 is in the form of a profile whose section has a V shape. This profile extends substantially parallel to the support plane PS ( Figures 1, 9, 10, 13, 15, 16) located at the rear of said base 110; 210. Its longitudinal axis defines a pivot axis Al; B1 for broom 124; 224 (figures 1, 9, 10, 13, 15, 16).
- Each broom 124; 224 is in the form of an L-shaped plate, one branch of which is received by its edge in the yoke 123; 223 so as to establish electrical contact and the other branch carries at its free end a movable contact grain 124A; 224A ( Figures 2 and 13).

- each trainer 126; 226 drives the movement of the spring, which drives the movement of the brush 124; 224 correspondent.
- each trainer 126; 226 controls the tilting of each trainer 126; 226 towards one of its positions, which causes the tilting of the elastic tilting means 129; 229, and therefore of the broom 124; 224 associated, so as to put in contact or out of contact the movable contact element 124A; 224A with the fixed contact element 132; 232.
- the two positions of each trainer 126; 226 correspond to the two extreme positions of the brush 124; 224.
- each trainer 126; 226 thus drives the movement of the spring, which drives the movement of the brush 124; 224 so as to allow rapid and precise tilting of the brush between the two extreme positions while avoiding the formation of electric arcs.
- the same base therefore has mounting means making it possible to accommodate a single trainer in the case of a single control or two different trainers in the case of a double control.
