Abstract: A touch input device with a button function is provided. The touch input device includes a base plate, a touch module, an elastic element, and a triggering element. When the touch module is depressed, the triggering element is triggered to generate a touch signal. The triggering element is arranged between the base plate and the touch module. The elastic element is disposed around the peripheral area of the base plate. Since the elastic element is contacted with the peripheral area of the touch module, the elastic force provided to each position of the touch module is substantial equal. Consequently, the tactile feel on each position of the touch module is nearly identical for the user.

Abstract: A key structure includes a keycap, a connecting member, a fixing member, a light emitter and a light receiver. The connecting member is connected to an inner top surface of the keycap and extends downwards, and the connecting member has a first opening through the connecting member. The fixing member has a second opening through the fixing member, in which when the keycap is initially pressed and then continues to be pressed, the keycap moves in a direction, and the connecting member moves with the keycap, and an overlapping region defined by the first opening and the second opening gradually becomes larger or smaller. The light emitter is laterally adjacent to the second opening of the fixing member. The light receiver is laterally adjacent to the first opening of the connecting member.

Abstract: A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.
