Abstract

An adjustable key cap, which is disposed upon a key seat having an axial pillar and an axial seat, and enables the axial pillar to move with respect to the axial seat for generating a signal, includes a main body, a key travel adjustment device, and a key press adjustment device. The main body moves upward and downward with respect to the key seat. The key travel adjustment device adjusts an interval size for the axial pillar to trigger the signal. When the main body moves upward or downward with respect to the key seat, the key press adjustment device can vary a feedback strength produced by the axial seat with respect to the main body. Therefore, the user can change the trigger flexibility and the press force of the keyboard through the key cap, without the need of disassembling the keyboard by professional personnel or tool.
