A switch lock device of a railway switching actuator (1) connected to a switching slide (16) and a tie bar/locking slide (2) of said actuator (1), said switching slide (16) and a tie bar/locking slide (2) being slidable one over the other so as to lock a blade of a railway switch in a closed position, the switch lock comprising an oscillating catch unit (8) articulated at the end of the tie bar (2) in an oscillating way between two positions wherein it engages respectively a stationary step (26) of a casing of the actuator (1) and a head surface (28) of the switching slide (16),characterized in that the oscillating catch unit (8) is linked to the end of the tie bar (2) by means of a spring actuated mechanism (30) arranged to block the oscillation of the oscillating catch unit (8) in an unlocked position corresponding to the engagement of the switching slide (16) so that, when during a switching maneuver the tie bar (2) exercises a compression on the spring actuated mechanism (30), the oscillating catch unit (8) is made free to oscillate towards a locking position in which it engages the step (26) of the casing of the actuator.
