Abstract
A keyboard includes a substrate, a display member, and a keyswitch assembly. The display member is disposed over the substrate. The keyswitch assembly includes a keycap, a fixing element, two balance bars, and a position-returning member. The keycap is located over the substrate and has a light-transmitting portion located over the display member. The fixing element is disposed on the substrate and has a retaining slot. Each of the balance bars includes a rod portion and an end portion. The rod portion is rotatably engaged with the keycap. The end portion is movably retained in the retaining slot. The position-returning member abuts against the keycap above the substrate and is adjacent to an edge of the keycap.
