<p>An electromechanical device (10) for locking/releasing a mechanism (11) for the manual operation of an actuation shaft (12), particularly of an electrical disconnector, comprising - a detent (13) for locking the rotation of the actuation shaft (12) which can perform a translational motion with respect to the shaft in order to engage therein, so as to lock its rotation, and disengage from it, in contrast with a return spring (14), to release its rotation, - an electrical contactor (15) with a movable element (16), which is coupled in a cam-like arrangement to the detent (13) and is adapted to be arranged, with respect to the detent, in two alternative configurations, respectively a configuration for preventing and a configuration for enabling the disengagement of the detent (13) from the actuation shaft (12), in order to prevent or release its rotation.</p> |
