The key shaft is pressed to drive a potentiometer arranged aside. The key shaft of the existing keyboard is composed of a plastic film or a mechanical structure, and the down force cannot be adjusted from the moment of leaving the factory, but the key shaft of the scheme can conveniently adjust the repulsive force between magnets through a PWM (pulse width modulation) technology to adjust the down force of the key shaft, so that the hand feeling can be changed. The traditional keyboard only has two states of pressing/not pressing, and the potentiometer of the scheme can tell a computer the stroke of the key shaft under the current pressing force through AD conversion, so that the size of a coil magnetic field when the requirement of obtaining the fixed stroke of the key shaft is adjusted, and the key hand feeling adapted by a current user is determined. Under the condition that the coil repulsion force is fixed, different key shaft strokes can be obtained by different key forces, so that different potentiometer signals are obtained, and the computer can make different responses according to the different potentiometer signals, so that the operability in game entertainment can be greatly enriched. The mechanical key shaft is provided with a shaft body with a section falling feeling and a shaft body without the section falling feeling, the key shaft can sense the position of the key shaft by using a potentiometer, and when the key shaft is pressed down to a certain degree, the coil power-off repulsive force disappears, so that the section falling feeling can be simulated. According to the scheme, the key shafts can move by themselves under the independent control of the repulsion force of each coil, the key shafts on the keyboard are linked to play animations, the ornamental performance is high, and the key shafts can be lifted in a scale-to-scale ratio when the keyboard is started. Different from the existing keyboard, the electromagnetic repulsion keyboard greatly enriches the operability of the keyboard and simultaneously realizes a large number of functions.

Preferably, the potentiometer is a rotary potentiometer, and a rotating shaft of the potentiometer is perpendicular to the key shaft and is attached to the key shaft.

Preferably, the side surface of the lower end of the key shaft is of a rack structure, and the joint of the rotating shaft of the potentiometer and the key shaft is a gear meshed with the rack structure.

Preferably, the outer diameter of the coil does not exceed the width of the keycap.

Preferably, the panel is a PCB.

The utility model discloses the resilience force of key shaft is provided by the strength that homopolar repulsion between the magnetic field of coil circular telegram and the permanent magnet to can adjust, the key shaft drives when being pressed and settles the potentiometre on one side, and the maneuverability of keyboard has been richened greatly to electromagnetic repulsion keyboard, has realized a large amount of functions simultaneously.
