The cyclic electromechanical program control comprises an electric motor (6), a gear train (7) driven by the motor and having an impulse gear (26) and an output gear (5) which is engaged with at least one driving rack (3, 4) for an element (1) having a programmable shifting cycle, a driven gear (9) cooperative with the gear train (7) for receiving from the gear train impulses controlling the cycle of the programmable element (1), an electrical circuit (12, 13, 17, 18) associated with the driven gear (9) and adapted to transmit to the motor (6) instructions corresponding to the nature of the impulses received by the driven gear (9). The control further comprises a mechanism for causing th impulse gear (26) to deliver impulses solely in predetermined useful zones of the cycle of said programmable element (1). The gear train (7) is a differential gear train comprising a driving gear (25) without gearing down of the output gear (5). The program control only delivers driving impulses in useful zones of the cycle and with a precision much higher than that of known program controls.
