Abstract
A key structure includes a base plate, a keycap, a scissors-type connecting member, and an elastic element. The scissors-type connecting member is connected with the base plate and the keycap. After the key structure is assembled and the keycap is not assembled, the elastic element provides an upward first elastic force, and the scissors-type connecting member is bent to provide a downward second elastic force. By exerting a small force on the keycap, the key structure can be triggered.
