Summary:The frog of the switches and switch constructions, wherein its wing rails (1, 2) are removably connected with the vee-piece toe (3) and continuing toe rails (4) by screws (5) via hollow trunnions (6) embedded in a recession of rotation shape (7) coaxially placed in relation to holes (8) for the screws (5), placed in wing rails (1, 2) and the vee-piece toe (3) connected with the toe rails (4). The method of production of the frog of switches and switch constructions, wherein wing rails (1, 2) and the vee-piece toe (3) with toe rails (4) are connected in crude form using the screws (5) and hollow trunnions (6) via the holes (8) and the recession (7) of rotation shape and then it is machined as one unit to final shape.
