The present invention is an elevator switch improving the restoration elasticity of upward and downward operation that forms a main gap of a constant gap space on the top of three thin main bands so that the bands are formed on a bottom end of a border ring of a pusher attached to the bottom of a button. The switch forms a convex protrusion on the bottom middle of the main bands so that the button and the pusher move downwardly while the main bands move toward to the constant gap space by three convex protrusions attached to a top surface of acircuit board when the button is pushed. When the button is released, the button and the pusher return to the original state while the main bands which move toward the constant gap space of the bottom end of the border ring move downwardly by self-elasticity. |
