Device for interrupting electric current with simplified structure

摘要

The device has a shoulder (61) connected to a housing, and a retaining unit (6) including a pawl (62) pivotingly mounted on a carriage (3) around a pivoting axle (X). The pawl has a support surface (623) engaged with the shoulder for maintaining the carriage in a retaining position. A connecting rod has an end (522) engaged with a cam to pivot the pawl in a disengagement direction (D) around the axis when an actuating unit (5) passes from an engagement position to an escape position. The surface escapes the shoulder from the housing when the actuating unit crosses the escape position.
