Abstract
A electromechanical programmer with smooth program preselection having a rotating main cam unit for executing several operating programs, a first cam for allowing step passage with the main cam unit driven in rotation by a micromotor through a speed reduction system, and a second cam for smooth program preselection. The programmer comprises a retractable mechanical drive device for assuring a mechanical connection between the rotating main cam unit and first cam for allowing step passage under a control of the second cam for smooth program preselection.
