ABSTRACT:
A rotating cam member incrementally moves through a discrete plurality of angular positions to sequentially actuate in a predetermined pattern an array of switches controlling, for example, the operation cycles of a domestic appliance such as an automatic dishwasher or clothes washer. The rotating cam member is driven from one angular position to the next by a motor under the control of a programmable integrated circuit timer determining the dwell time of the cam member at each of its angular positions. Varying the dwell time of the cam member at each of its angular positions readily permits a more flexible and complex operating cycle sequence for the appliance being controlled as compared to prior art electromechanical timer devices.
