Abstract
A key structure includes a base plate, a keycap, a connecting assembly, a protrusion and a limiting member. The connecting assembly includes a first frame and a second frame pivotally connected to each other. Two opposite ends of the first frame are movably connected to the base plate and the keycap, respectively, and two opposite ends of the second frame are movably connected to the base plate and the keycap, respectively, to drive the keycap upward and downward relative to the base plate. The protrusion is disposed on a sidewall of the first frame or a sidewall of the second frame. The limiting member corresponds in position to the protrusion. When the keycap is at a maximum height, the protrusion abuts against the limiting member.
