A key structure includes a circuit board, a keycap, an elastic member and a metal member. The keycap has a bottom facing the circuit board. The elastic member is disposed between the circuit board and the keycap. The elastic member includes a dome portion, a hollow portion, and a contact pillar. The dome portion touches the bottom of the keycap. The hollow portion is located inside of the dome portion. The contact pillar is located in the hollow portion, and the contact pillar extends from the dome portion to the circuit board. The metal member covers the outside of the contact pillar. The metal member comprises a trigger portion, and the trigger portion is a convex portion extending toward the circuit board.

Key structure

A keyboard includes a bottom plate and keyswitch devices. Each keyswitch device includes a keycap, a first supporting member, and a second supporting member. The keycap is over the bottom plate. The first and second supporting members are connected between the bottom plate and the keycap and respectively include first and second magnetic attraction portions. The second magnetic attraction portion is configured to attract the first magnetic attraction portion. The first and second magnetic attraction portions respectively have first and second abutting surfaces. When the first abutting surface abuts against the second abutting surface, the keycap is at a highest position relative to the bottom plate. When the keycap moves toward the bottom plate from the highest position, the first abutting surface is at least partially separated from the second abutting surface.
