Abstract

The invention discloses a keyboard comprising a substrate and a plurality of keyswitches. The keyswitches are disposed on the substrate. The substrate includes a first connection portion and a reinforcement structure. The first connection portion is formed from bending the substrate. Each keyswitch includes a keycap and a lift support device. The keycap has a second connection portion. The lift support device is disposed between the keycap and substrate. The lift support device has a third connection portion and a fourth connection portion. The first connection portion is connected to the third connection portion, and the second connection portion is connected to the fourth connection portion. The lift support device is used for carrying the keycap to move vertically relative to the substrate. The reinforcement structure can enhance the connection strength between the first connection portion and the substrate.
