Abstract: A key switch is disclosed. The key switch includes an axis, a pressure sensor layer, an axis component, and a key cap. The axis support includes a first opening. The pressure sensor layer is made of a pressure-sensitive electronic material and disposed on an upper surface of the axis support. The axis component is disposed in the first opening and vertically movable with respect to the axis support and the pressure sensor layer. The keycap is mounted on the axis component and includes a lower surface facing the upper surface of the axis support. When the keycap is depressed, the lower surface of the keycap depresses the pressure sensor layer and an electronic property of the pressure sensor layer varies. An analog pressure detection system including the key switch is also disclosed.
