  • Patent number: 4405914
    Abstract: A thermal fuse is comprised of a pair of internested, flat, thin metallic plates, each plate having peripheral upturned flanges along opposite edges of the plate. The flanges of the lower plate each have a notch formed therein and the upper plate has a tab extending transversely from each side through a respective notch. The notches each have a side inclined to the plate to form a ramp, the edge corners of the tabs being cammed up the ramp of the respective notches when the plates are pulled apart in a direction parallel to the plane of the plates, to lift the upper plate perpendicularly away from the lower plate so that the flat confronting surfaces of the plates are drawn apart.
