Abstract

An appliance control system includes a housing and a user cycle selector which is movable in relation to the housing between a first selector position and a second selector position. The appliance control system further includes a first spring secured to the housing, the first spring being configured to retain the user cycle selector at (i) the first selector position during a first period of time, and (ii) the second selector position during a second period of time. Additionally, the appliance control system includes a mode switch positioned within the housing, the mode switch having an actuated state and a deactuated state: The appliance control system also includes a second spring having a spring arm which is movable between a first arm position and a second arm position. Movement of the user cycle selector from the first selector position to the second selector position causes the spring arm to move from the first arm position to the second arm position. And movement of the spring arm from the first arm position to the second arm position causes the mode switch to be switched from the deactuated state to the actuated state.
