  • Patent number: 4794213
    Abstract: A delayed action switch actuator includes a spring attached to one corner of a face plate, a suction cup and a ring-like toggle engaging member, sized to surround the toggle passing through the face plate, connecting the spring to the suction cup. The spring is sized to be in tension when the toggle-engaging member is in a toggle-engaging position. The suction cup is affixable to a roughened surface area on the face plate. The suction cup forms an imperfect seal with the roughened surface area, which results in the suction cup releasing after a period of time, such as a minute or two. The toggle is located between the point of attachment of the spring on one side of the face plate and the roughened area on the other side of the face plate. When the suction cup releases, the spring, which is in tension, pulls on the toggle-engaging member which subsequently trips the toggle.
