ABSTRACT:
A gravity switch for automatic control of an operative cycle in an appliance, such as a toasting cycle in a toaster oven or the like, includes an imbalanced weight member interposed between a displaceable member that moves in accordance to operation of the cycle and mechanical component parts operative between an OFF position and an ON position. During ON cycle operation, the imbalanced weight member is directly supported against the pull of gravity by the displaceable member. When the cycle operation reaches completion, the displaceable member is sufficiently moved so as to cause the release of the imbalanced weight member which is then free to move under the influence of gravity. This gravitional action initiates an interaction among the mechanical component parts resulting in quick return to the OFF position causing the cycle operation to rapidly terminate.
