Abstract:
An elastic button apparatus with an elevation mechanism, the elastic button apparatus comprising:a base; a key top, located above the base, the elevation mechanism located between the base and the key top and guiding lifting and lowering operation of the key top above the base; and a complex elastic unit, located between the key top and the base for providing resilience to the lifting and lowering operations including a lower elastic element located on the base and an upper elastic element located below the key top; wherein the complex elastic unit generates an S-shaped resilience pattern during the lifting and lowering operations through decreasing of spacing between the key top and the base and compression of the upper elastic element and the lower elastic element, wherein the lower elastic element is a conical elastic element with a convex side facing upwards, and wherein the upper elastic element is a pair of repulsive magnets located respectively on a bottom side of the key top and a top end of the lower elastic element.
