A connection component of the key is connected between a keycap of the key and a bottom plate connection portion of key bottom plate, and the bottom plate connection portion has a connection portion surface corresponding to the keycap and a raised portion formed on the connection portion surface. When the keycap moves downward relative to the thin film circuit board, a lower surface of the keycap knocks the raised portion.
