A selecting device for cross-point switches which have a first group and a second group of parallel bars crossing each other. The bars are individually displaceable between two outer positions and in the crossing points there are contact means and selecting elements for operating the contacts. Each bar included in said first group activates upon displacement selecting elements located along said bar and each bar included in the outer group activates upon displacement by means of said selecting elements, contact means located in the crossing point. Each of the selecting elements includes a leaf spring fastened at one of its ends on a bar in said second group and having at its free end a lifting stud projecting towards the bar in said first group. The bars of the first group have a sloping surface and said stud can slide on said surface and lift the leaf spring so as to operate the contact. The position of the sloping surface is such that a displacement of a bar in one of said groups is necessary to bring said sliding surface into engagement with said stud and a displacement of a bar in the second group is necessary to bring the stud to slide along said surface and to lift the contact.
