Abstract: A keyboard includes a base, a keycap, and a connecting assembly. The keycap is located over the base. The connecting assembly is located between the base and the keycap and includes a first connecting member and a second connecting member connected to each other. Each of the first and second connecting members is connected to the base and the keycap. Two connected members of the base, the keycap, and the first and second connecting members are fixedly connected. When the keycap is pressed toward the base, at least one of the first and second connecting members elastically deforms to store elastic potential energy. When the keycap is released, said at least one of the first and second connecting members elastically recovers to return the keycap to its original position.

Abstract: A touch stylus includes a stopper, a rod, a pressing element, a force sensor, and an elastic element. The rod and the pressing element are moveable relative to the stopper. The pressing element includes a first pressing portion, a second pressing portion, and at least one support arm. The first pressing portion is located between the rod and the stopper. The stopper is located between the first and the second pressing portions. The support arm extends from the first pressing portion to the second pressing portion. The force sensor is disposed between the stopper and the second pressing portion. The elastic element is connected to the pressing element. When the pressing element is located at a first position, the pressing element abuts against the force sensor. When the pressing element is located at a second position, the pressing element and the force sensor are separated from each other.
