Abstract: Key structures are provided. A key structure includes a key cover, a substrate, a slider movable with respect to the substrate, a first rod, a second rod and a resilient member. The first rod pivotally connects the key cover and a first guiding portion of the substrate. The second rod pivotally connects the key cover and a second guiding portion of the substrate. The resilient member connects the substrate and the first rod, and exerts a lateral force on the first rod. When the key structure is in a normal state, a first contact portion of the slider contacts and restricts the second rod. When the key structure is switched from the normal state to a depressed state, a second contact portion of the slider impels the second rod outward of the key structure, such that the key cover descends toward the substrate.
