ABSTRACT:
An actuating mechanism for example for an electric switch comprises a driving member, a driven shaft and a transmission gearing through which the driven shaft is driven by the driving member through a certain angle of rotation after a predetermined number of revolutions of the driving member. An actuator carried by the driven shaft is operative at a predetermined angular position of the driven shaft. An adjustment shaft is provided which can be rotated to rotate the driven shaft through the transmission gearing, a clutch being connected between the driving member and the transmission gearing to permit by disengagement of the clutch the adjustment shaft to rotate the driven shaft relatively to the driving member. A radial projection, e.g. an arm, is provided on the driven shaft in a fixed angular relationship to the actuator thereon, and a removable abutment stop for the radial projection is provided at a predetermined angular position with respect to the axis of the driven shaft to limit the angular displacement of the driven shaft by the adjustment shaft.
