Switch machine for a railroad switch equipped with: - a movement group configured to translate along a movement direction in a first displacement direction, or in a second displacement direction opposite to the first, to alternatively move, at least a switch point (101,102) between two limit positions in which switch point is, respectively, closed to, or spaced from, a respective rail stock; - an actuation group configured to actuate said translation of said movement group along said movement direction, said actuation group comprising at least a hydraulic actuator having a hollow main body provided with a longitudinal cavity and slidingly mounted on a fixed stem configured to define in said longitudinal cavity a first and a second opposite pushing chambers (77,78), said movement group being caused to slide in said first direction, or in said second displacement direction, according to the pressure exerted by a working fluid in said first, or in said second pushing chamber (77,78); - a feeding group comprising a pumping device and configured to alternatively and selectively feed a predetermined constant flow of said working fluid in said first, and in said second pushing chamber (77,78), through a hydraulic feeding circuit, said feeding group being arranged to feed said working fluid at a predetermined initial pressure pi corresponding to a pushing force Fi; - a locking/unlocking group arranged to move from a locking configuration, in which is arranged to impede said translation of said movement group, to an unlocking configuration, in which is arranged to allow said translation of said movement group; said switch machine further providing: - a control group configured to reduce said initial pressure pi of said working fluid within said first, or said second, pushing chamber, up to a predetermined value p*, in such a way to correspondingly reduce the pushing force exerted by said hydraulic actuator up to a predetermined value F* in order to prevent said actuation group from further sliding if an external force greater than said pushing force F* acts; characterised in that an operating group (231,232) is, furthermore, provided configured to operate said control group when said actuation group, during said motion of said movement group along said movement direction, reaches a predetermined actuation position at which said switch point is positioned at a predetermined distance d* from the respective stock rail (111,112), with d* less than a predetermined threshold distance, in such a way to reduce said pressure of said working fluid up to said predetermined value p* in proximity of said limit position. - a movement group configured to translate along a movement direction in a first displacement direction, or in a second displacement direction opposite to the first, to alternatively move, at least a switch point (101,102) between two limit positions in which switch point is, respectively, closed to, or spaced from, a respective rail stock; - an actuation group configured to actuate said translation of said movement group along said movement direction, said actuation group comprising at least a hydraulic actuator having a hollow main body provided with a longitudinal cavity and slidingly mounted on a fixed stem configured to define in said longitudinal cavity a first and a second opposite pushing chambers (77,78), said movement group being caused to slide in said first direction, or in said second displacement direction, according to the pressure exerted by a working fluid in said first, or in said second pushing chamber (77,78); - a feeding group comprising a pumping device and configured to alternatively and selectively feed a predetermined constant flow of said working fluid in said first, and in said second pushing chamber (77,78), through a hydraulic feeding circuit, said feeding group being arranged to feed said working fluid at a predetermined initial pressure pi corresponding to a pushing force Fi; - a locking/unlocking group arranged to move from a locking configuration, in which is arranged to impede said translation of said movement group, to an unlocking configuration, in which is arranged to allow said translation of said movement group; - a control group configured to reduce said initial pressure pi of said working fluid within said first, or said second, pushing chamber, up to a predetermined value p*, in such a way to correspondingly reduce the pushing force exerted by said hydraulic actuator up to a predetermined value F* in order to prevent said actuation group from further sliding if an external force greater than said pushing force F* acts;
