Abstract: A roller input device includes a substrate, a bracket assembly, a roller seat, and a stopping member. The substrate has a top surface provided with a click button switch and a first tilt button switch. The bracket assembly and the roller seat are disposed on the substrate. The roller seat is pivotally connected to the bracket assembly. The stopping member is connected to the roller seat and has a first stopping portion. A first initial spacing is between the first stopping portion and the top surface. When the roller seat is at a pressing position, the first initial spacing is reduced to a first spacing being less than a first pressing stroke of the first tilt button switch. When the roller seat is at a first tilt position, the first initial spacing is reduced to a second spacing being less than a click pressing stroke of the click button switch.

Abstract: A mouse includes a main housing, a key structure, and a pressing force adjusting component. The key structure has a connecting end, a free end, and an elastic section. The connecting end is connected to the main housing, and the elastic section is located between the connecting end and the free end. The pressing force adjusting component is movably disposed on the main housing and has a limiting portion, and the limiting portion limits elastic deformation of the elastic section. A location of the pressing force adjusting component on the main housing is adapted to be changed to change a location of the limiting portion at the elastic section.

Abstract: An inductive component includes: a ferromagnetic core; a coil made of aluminum and having a winding portion wound around the ferromagnetic core for a predetermined number of turns, and two extending portions extending respectively from two ends of the winding portion; and two terminals made of copper. Each terminal wraps around a respective one of the extending portions.
