An electromechanical programmer having a user push-push reset action on the shaft of a rotary cam drum for actuating plural appliance function switches. Successive user push movements alternately latch and release the shaft between first and second axial positions. In the first axial position the shaft moves an auxiliary cam to close a line power switch for energizing a motorized cam drum advance and powering the program switches; and, the shaft is free-rotating with respect to the cam drum. In the second axial position the shaft moves an auxiliary cam to open the line power switch; and, the shaft is clutched to the drum to enable user rotation of the drum for appliance program interval selection.
