This article describes a simple and inexpensive self-restoring torsional latch in which the latching action is provided by a wire restrained at one end but rotatable at the other. Referring to the drawing, the latch includes a wire 10 which is restrained at one end by a pair of ribs 12 and 14 in one wall of a base structure 16. The opposite end of the wire 10 is coupled to a knob 18 which is journaled in the opposite wall of the base structure. The journaled end can be rotated between a latched position 20 and an unlatched position 22. The base structure includes a preferably integral beam spring 24. The wire 10 is capable of retaining a catch 26 for a cover (not shown). The catch 26 is shown both in its retained position and (in dotted outline form) in its free position.
