1. A button assembly, comprising:
a bottom plate;
a cap disposed on the bottom plate, the cap having a button surface and an inner surface on opposite sides, wherein the cap has two pairs of interference members disposed on the inner surface and protruding toward the bottom plate;
an elastic member disposed under the cap; and
a link member having two parallel portions parallel to each other and a horizontal portion connected with the two parallel portions, wherein the two parallel portions are disposed on the bottom plate and the horizontal portion is snapped into the pair of interference members, wherein the two pairs of interference members are arranged along an axial direction of the horizontal portion, and one pair of the two pairs of interference members is offset along an axial direction of the parallel portion to dislocate from an other pair of the two pairs of interference members,
wherein a central axis of the horizontal portion engaged with the one pair of the two pairs of interference members is coaxial with a central axis of the one pair of the two pairs of interference members,
the central axis of the horizontal portion engaged with the other pair of the two pairs of interference members is coaxial with a central axis of the other pair of the two pairs of the interference members, and deviates from the central axis of the one pair of the two pairs of interference members.
