Abstract
A keyswitch device includes a circuit board, a fixing bracket, a micro switch, a keycap, and a connecting assembly. The circuit board has a first surface and a second surface opposite to the first surface. The fixing bracket includes a main body and a first hook. The main body abuts against the first surface. The first hook is connected to the main body and fixed to the circuit board. The micro switch passes through the main body, and is disposed on the circuit board and configured to generate a pressing signal to the circuit board while being pressed. The keycap is supported on the micro switch and configured to press the micro switch toward the circuit board. The connecting assembly is connected between the fixing bracket and the keycap and configured to guide the keycap to move upward and downward relative to the circuit board.
