Abstract: The present invention relates to an input device. The input device includes a circuit board, a wheel, a supporting frame, a push button switch and a tilt switch. The wheel has a rotary shaft. The supporting frame includes a body, an extension arm, a first and a second supporting portion. The wheel is pivotally connected to the body by the rotary shaft. The extension arm is disposed at the side edge of the body. The first and second supporting portion are connected to the body, where the second supporting portion is disposed between the rotary shaft and the first supporting portion. The push button switch is corresponding to the body. When the wheel is pressed, the body is driven to trigger the push button switch. The tilt switch is corresponding to the extension arm. When the wheel tilts, the extension arm is driven to trigger the tilt switch.
