ABSTRACT:
An electromechanical programmer assembly for controlling electrically operated appliances having a rotatable cam drum operable upon motorized advancement to actuate and deactuate plural program switches for controlling appliance functions. A user actuated shaft is rotated to select the desired cam drum position for program selection. Axial movement of the shaft causes a cam thereon to lift a slider for opening a line power switch for controlling the motorized cam drive and engaging a friction detent on the cam drum for resisting rotation of the drum and to provide a tactilely sensed position indication to the user. Axial movement of the shaft to effect dropping of the slider closes the line power switch and disengages the detent.
