A dynamically self-stabilizing elastic keyswitch for a key of a keyboard includes a rigid keytop, a thin elastic sheet, and a downward-facing convex rigid key bottom. The rigid keytop has a central axis at least substantially perpendicular to a surface of the rigid keytop. The thin elastic sheet is disposed relative to the central axis, and the central axis is at least substantially perpendicular to a surface of the thin elastic sheet. The downward-facing convex rigid key bottom is disposed relative to the central axis and below the rigid keytop, and the central axis is at least substantially perpendicular to a surface of the downward-facing convex rigid key bottom.
