Abstract: A mouse device includes a main body, a press-button, a sliding button movably disposed on the main body, an adjusting member connected to the sliding button, an elastic element disposed on the adjusting member, a loading seat and an arm-swing seat disposed in the main body. The main body has a receiving space and a switch module disposed therein. The press-button has a trigger portion. The loading seat has a first surface and a second surface on a bottom thereof with different level heights. The arm-swing seat has a swing arm disposed between the trigger portion and the switch module. The switch module is triggered by the trigger portion and the arm-swing seat. The elastic element is synchronously moved with the sliding button and has an abutting portion selectively abutted against the first surface or the second surface to provide different loads for the press-button.
