Keyboard

A keyboard comprising:

• a magnetic plate for producing a magnetic field;
• a circuit board including
• a board body that is disposed on said magnetic plate along an up-down direction, and that has multiple key regions, each of said key regions being formed with multiple positioning holes, and
• multiple triggers that are disposed respectively on said key regions of said board body;
• and
• multiple keys disposed respectively at said key regions of said board body along the up-down direction and corresponding respectively to said triggers, each of said keys including
• a keycap,
• a metal plate that is disposed below said keycap along the up-down direction, and that is attracted by said magnetic plate along the up-down direction under the magnetic field so as to be removably attached to the respective one of said key regions of said board body, said metal plate having a plate body that is formed with a through hole aligned with the respective one of said triggers, and multiple positioning pins that extend downward from said plate body opposite to said keycap respectively into said positioning holes at the respective one of said key regions of said board body,
• a scissor switch that is disposed between said keycap and said metal plate, and
• an elastic component that is disposed on said metal plate and extends into said scissor switch,
• wherein, when one of said keys is pressed, said keycap of said one of said keys is brought to drive said scissor switch of said one of said keys, and to push said elastic component of said one of said keys downward such that a part of said elastic component extends through said through hole of said metal plate of said one of said keys to press the respective one of said triggers.
