A large key for a keyboard includes a keyboard base, a circuit board, a keycap, an elastic member, and a linkage assembly. The linkage assembly is disposed between the keyboard base and the keycap, and includes: a first link unit having two first link levers that are spaced apart, each of the first link levers being connected between the keycap and the keyboard base; and a second link unit that has two second link levers that are spaced apart, each of the second link levers intersecting one of the first link levers and being connected between the keycap and the keyboard base. The first link unit has a first connection portion connected between and formed as one piece with the first link levers so that the two first link levers can move simultaneously. |
