Abstract

A ratchet and replacement device in switch disks driven by the pulse wheel thereof, for telecommunication, particularly telephone equipment, whose device carries said ratchet, after actuating the switch disk to its starting position for the pulses, characterized by a helical spring (7) prestressed in radial and axial direction, slid on an extension of the axle 8 of the pawl (1) and the ends (12 and 13) of said spring project in radial direction always touching one of the stops connected to the movable pawl when it actuates the commutator disk and during the return of the pulse wheel alternately touch a stop (14, 15) provided on the base plate (2) and the support plate (3) respectively.
