ABSTRACT OF THE DISCLOSURE A snap-action hinge includes a swingable portion having a first thickness, a reference portion having a second thickness, at least one of these portions being substantially planar, and a substantially linear connecting portion having a reduced thickness substantially less than the first and second thicknesses. The connecting portion is integral with the swingable and reference portions and extends continuously between first and second points in a manner such that the connecting portion follows a bowed path which is displaced from a straight line connecting the first and second points, whereby upon swinging the swingable portion about the connecting portion the swingable portion swings through an intermediate unstable position such that the planar portion has a first bowed configuration on one side of the intermediate position and a second bowed configuration on the other side of the intermediate position. The bowed configurations comprising stable positions relative to the intermediate unstable position whereby the planar portion is urged by stress created therein into one of the stable positions when displaced therefrom.
