    DETAILED DESCRIPTION OF THE INVENTION

    (12) To render the objectives, technical solutions and advantages of the present disclosure clear and comprehensible, the present disclosure is illustrated by specific embodiments and accompanying drawings and described below.

    Embodiment 1

    (13) FIG. 1 illustrates how balance rods are applicable to a standard 1X key of a magnetic keyboard in this embodiment. The key comprises a base plate 1, a sensing component 2, an elastomer 3, an intermediate plate 4, a magnetic component 5, an upper cover 6, a magnetized iron plate 7, a keying portion 8, a first balance rod 10, and a second balance rod 9.

    (14) The sensing component 2 has a thin-film circuit. The sensing component 2 is disposed on the base plate 1. The sensing component 2 further has a through hole 21 which penetrates upper and lower surfaces of the sensing component 2. The through hole 21 corresponds in position to the second balance rod 9 and the first balance rod 10.

    (15) The elastomer 3 is disposed on the sensing component 2 and has a bump 31 disposed in a key hole 41 of the intermediate plate 4. The height or structure of the elastomer 3 is adjustable, so as to adjust the feel of the key.

    (16) The intermediate plate 4 has upper and lower surfaces. The intermediate plate 4 is above the sensing component 2. The intermediate plate 4 has the key hole 41 and a receiving chamber 42 which penetrate the upper surface and the lower surface of the intermediate plate 4. The receiving chamber 42 is disposed at an edge of the key hole 41. The intermediate plate 4 is made of a plastic and formed by injection molding. A balance rod connection mechanism 43 is disposed on the lower surface of the intermediate plate 4.

    (17) In this embodiment, the magnetic component 5 is disposed in the receiving chamber 42 of the intermediate plate 4. Optionally, the upper cover 6, which is made of PET film, adheres to the upper surface of the intermediate plate 4 to further prevent the magnetic component 5 from loosening or detaching, thereby allowing the magnetic component 5 to fit inside the surroundings of the magnetic key.

    (18) The magnetized iron plate 7 comprises an arm 71 and a hand 72. The arm 71 is disposed in the key hole 41 of the intermediate plate 4 and firmly connected to the lower surface of the keying portion 8. The hand 72 is disposed between the lower surface of the magnetic component 5 and the base plate 1. The arm 71 extends to reach the bottom of the keying portion 8 so as to connect to the hand 72, thereby allowing the hand 72 to be disposed below the magnetic component 5. The hand 72 and the magnetic component 5 are attracted, and thereby attached, to each other whenever the arm 71 is not subjected to any external force.

    (19) The keying portion 8 is disposed on the magnetized iron plate 7 and firmly connected to the arm 71 of the magnetized iron plate 7. In this embodiment, the keying portion 8 is made of a plastic. A balance rod connection mechanism 81 is disposed on the lower surface of the keying portion 8, as shown in FIG. 2.

    (20) Referring to FIG. 2, the second balance rod 9 is in the number of two, whereas the first balance rod 10 is in the number of one. The second balance rods 9 and the first balance rod 10 are disposed on the lower surface of the keying portion 8. Segments of the first and second balance rods 10, 9 are each movably connected to the connection mechanism 81 on the lower surface of the keying portion 8. The other segments of the first and second balance rods 10, 9 are each movably connected to the balance rod connection mechanism 43 of the intermediate plate 4. Optionally, a segment of at least one of the second balance rods 9, which is movably connected to the keying portion 8, is disposed on the inward side of the keying portion 8, whereas the other segment of the second balance rod 9, which is movably connected to the intermediate plate 4, is disposed on the outward side of the keying portion 8.

    (21) Relative positions of the three balance rods 9, 10 of FIG. 2 are shown in FIG. 3. The two second balance rods 9 run in the direction of X-axis, whereas the first balance rod 10 runs in the direction of Y-axis. The three balance rods 9, 10 neither cross nor overlap.

    (22) This embodiment not only illustrates how the balance rods are applied to a standard 1X key of the magnetic keyboard, but also shows that the balance rods are each connected between the keying portion and the intermediate plate in variable ways.

    (24) This embodiment improves and supplements embodiment 1, as shown in FIG. 4.

    (25) The intermediate plate 4 in embodiment 1 has only one receiving chamber 42. By contrast, the intermediate plate 4 in embodiment 2 has two receiving chambers 42.

    (26) Only one magnetic component 5 is provided in embodiment 1. By contrast, two magnetic components 5 are provided in embodiment 2.

    (27) Embodiment 1 requires two balance rods 9 and one balance rod 10, that is, three balance rods in total. By contrast, embodiment 2 requires one balance rod 9 and one balance rod 10, that is, two balance rods in total.

    (28) In embodiment 1, the arm 71 of the magnetized iron plate 7 has no through hole but one hand 72. By contrast, in embodiment 2, the arm 71 of the magnetized iron plate 7 not only has a through hole which penetrates its upper and lower surfaces, but also has two hands 72.
