Abstract (en)
A device (1) for manually actuating a railroad switch (100) comprises an operating tie-rod (20) that s able to translate along a translation direction in a first, or second, displacement direction, in order to displace a first and a second switch points (101, 102) between two limit positions. The device (1), furthermore, provides a displacement group (50) for causing the operating tie-rod (20) to translate along the translation direction in the first, or the second movement direction and an actuation member (55), which is operated by an operator for actuating the displacement group (50). The actuation device (1), furthermore, comprises a push element (40) rotatably engaged at a first end portion (41) in such a way to be able to rotate about a first rotation axis (140) orthogonal to the translation direction (120). The push element (40) moves from a first working configuration in which it exerts a pushing force, which opposes the translation of the operating tie-rod (20) from a limit position to an intermediate position, and a second working configuration in which it exerts a pushing force, which, instead, helps the above mentioned translation.
