ABSTRACT:
A timer for controlling an appliance includes a housing. The timer also includes a camstack having a plurality of cam surfaces defined therein. The plurality of cam surfaces are positioned within the housing. The timer further includes a switch block which cooperates with the plurality of cam surfaces to provide switching operations for the appliance. Moreover, the timer includes an auxiliary member having a circuit pattern positioned on a side thereof. Rotation of the camstack causes rotation of the auxiliary member. The auxiliary member is positioned outside of the housing. The timer yet further includes a first switch arm positioned in contact with the side of the auxiliary member. Rotation of the auxiliary member causes the circuit pattern to be advanced into contact with the first switch arm. A method of controlling an appliance is also disclosed.
