A key assembly comprises a base plate, two elastic elements and a key body. The elastic elements are both mounted to the base plate, and the elastic elements are spaced from and opposite to each other. The key body is slidably mounted to the base plate between the two elastic elements. The key body includes a first key section and a second key section connected with the first key section. The first key section has an arcuate first contacting portion formed thereon. The second key section has an arcuate second contacting portion formed thereon. The first key section resists one of the two elastic elements, the second key section resisting another elastic element. When the first key section slides toward and compresses the elastic element that resists the first key section, the second key section slide away from the elastic element that resists the second key section.
