Elastic dome

An elastic dome, used in a keyswitch structure, the elastic dome comprising:

• a bottom ring portion, the bottom ring portion having a narrowed upper portion and a lower portion connected to the upper portion;
• a top ring portion, the top ring portion being located above the bottom ring portion in a vertical direction;
• an outer oblique annular wall, the outer oblique annular wall being located between the top ring portion and the bottom ring portion in the vertical direction, two ends of the outer oblique annular wall being connected to the top ring portion and the upper portion of the bottom ring portion;
• a trigger post, the trigger post being located inside the outer oblique annular wall;
• and
• an inner oblique annular wall, the inner oblique annular wall extending obliquely downward from an inner side of the top ring portion and being connected to the trigger post, the inner oblique annular wall having a top conical surface;
• wherein when the elastic dome is compressed to a depressed state by a keycap of the keyswitch structure, a connection between the upper portion and the lower portion is higher than a connection between the top ring portion and the top conical surface in the vertical direction.
