Dual-action, spring-biased, snap-action latching structure including (a) first and second reversibly moveable relative-motion components operatively associated with one another, and each moveable between spaced first and second limit positions, and (b) biasing springs for these components, each urging its associated component in a common direction toward the component's first limit position. Motion of the first component from its first limit position toward its second limit position, against the resistance of the first component's biasing spring, accommodates snap-action movement of the second component toward its first limit position, and motion of the second component from its first limit position toward its second limit position, against the resistance of the second component's biasing spring, accommodates snap-action movement of the first component toward its first limit position. |
