Abstract
A magnetic key includes a keycap, a base plate, a membrane circuit member, a frame, a first magnetic element, a second magnetic element, and a third magnetic element. The frame includes a first concave structure, a second concave structure and an opening. An accommodation space is defined by the frame and a first protrusion structure and a second protrusion structure of the base plate. The first magnetic element is received within the first concave structure. The second magnetic element is received within the second concave structure. The third magnetic element is disposed under the keycap and accommodated within the accommodation space. In response to a first magnetic force between the first and third magnetic elements and a second magnetic force between the second and third magnetic elements, the keycap is protruded out of the opening.
