[0062] Please also refer to Figure 1 to Figure 3C , where, as figure 2 As shown, the keyboard 1 of the first embodiment has a circuit board 11, a keycap group 12, an adjustment member 13, a support elastic body group 14, a force transmission member group 15, a bearing plate 16, a trigger elastic body group 17 and a keyboard housing 18 . The force transmission component set 15 has a first force transmission component 151 and a second force transmission component 152 . The circuit board 11 is arranged on the carrier board 16, and the circuit board 11 has a first switch 111, a second switch 112, a pair of circuit board through holes 113 next to the first switch 111 and a pair of circuit board through holes next to the second switch 112. 114. The circuit board through-holes 113 and 114 are arc-shaped structures. Preferably, from a top view, the arc-shaped extension angle of the arc-shaped structures is less than 180 degrees. The carrier board 16 has a pair of carrier board t...
