FIELD: construction.SUBSTANCE: switch comprises a crosspiece (1), a spike (1a) of which moves between the first position of adjacency to the first counter-rail (2) and the second position of adjacency to the second counter-rail (3). The crosspiece has a support surface (4) for support of the spike (1a). The spike is arranged on the bracket (5), resting beyond the limits of the counter rails (2, 3) onto rollers (9a, 9b) to lift the spike of the crosspiece during displacement. Rollers move in guides (11a, 11b). Besides, one of the guides has lowered end sections (12a, 13a, 12b, 13b). The spike of the crosspiece interacts with the counter-rails at the bottom, the bracket has a base (6), comprising a receiving part (8) in the middle area for the crosspiece and lowered relative to the support sections (7a, 7b) that adjoin at the sides.EFFECT: higher reliability due to simplified design of a switch.6 cl, 3 dwg |
