Abstract
A keyboard key structure adopted for use on a larger sized key to provide users more effective depressing movements on the key includes two elastic domes to support a key cap in a non-depressed position. The two elastic domes are designed in an unsymmetrical fashion to equip with different compression displacements and flexibility and enable the key cap to move in one direction to reach a depressed position and complete signal input.
