A timer for controlling an appliance includes a cam having a first cam surface and a second cam surface defined therein. The first cam surface is distinct from the second cam surface. The timer also includes a first circuit blade which cooperates with the first cam surface so as to move between a first neutral position and a first actuated position. The timer further includes a second circuit blade which cooperates with the second cam surface so as to move between a second neutral position and a second actuated position. Moreover, the timer includes a third circuit blade which is positionable in a first offset position and a second offset position. The third circuit blade is positioned at the first offset position when the first circuit blade is positioned at the first actuated position. The third circuit blade is moved from the first offset position to the second offset position when the first circuit blade is moved from the first actuated position to the first neutral position. The third circuit blade contacts the second circuit blade when the third circuit blade is positioned in the second offset position and the second circuit blade is positioned in the second actuated position. A method of operating an appliance timer is also disclosed.
