Working principle:

when the mechanical keyboard is in a standby state or a power-off state, as the rebound spring 4032 and one end of the magnet block 403 are made of ferromagnetic materials, the magnet block 403 slides along the directional conductive groove 4012 under the action of magnetic force and the elasticity of the rebound spring 4032 through the rebound rod 4031, and when the mechanical keyboard slides, one end of the magnet block 403 with the magnet contacts with the conductive metal rod 4021 due to the ferromagnetic materials of the conductive metal rod 4021, when the mechanical keyboard works, firstly, a user inputs keys, when the mechanical shaft 3 of the mechanical keyboard is in an intact state, when the key cap 2 is pressed down, the switch upper cap 302 is caused to move downwards, the pressing spring 304 is compressed, and when the switch lower cap 303 is caused to release the blocking of the movable and static piece 3052, the movable and static piece 3052 contacts with the trigger piece 3054, the first coil 4022, the moving and static plates 3052 and the trigger plate 3054 are led to form a passage, so that key information marked by the key cap 2 is output, meanwhile, the conductive metal rod 4021 is magnetic due to the conduction of the first coil 4022, so that the conductive metal rod 4021 pushes the magnet block 403 away, the magnet block 403 and the conductive metal rod 4021 form an open circuit, the guide post 3021 at the bottom end of the upper switch cap 302 is led to be pressed to the inching switch 3053 along with the continuous pressing, after the inching switch 3053 is pressed, the magnet block 403 and the second dense coil 4023 are led to form a passage through the inching switch 3053, but because the magnet block 403 and the conductive metal rod 4021 are influenced by the magnetism of an electromagnet of the conductive metal rod 4021 at the moment, the magnet block 403 and the conductive metal rod 4021 are led to open circuit, at the moment, the elasticity of the pressing spring 304 is released along with the loosening of a user, so that the key is restored to an initial state, at this time, the electromagnet assembly 402 loses magnetism, so that one end of the magnet block 403 with the magnet is contacted with the conductive metal rod 4021, normal use is not affected in the process, and the mechanical keyboard emits normal sound;

when the moving and static plate 3052 or the trigger plate 3054 is blocked or rusted and then cannot conduct electricity normally, at this time, when the user presses the key cap 2 unknowingly, the switch upper cap 302 is caused to move downwards, the pressing spring 304 is caused to be compressed, and when the switch lower cap 303 is caused to release the blocking of the moving and static plate 3052, the moving and static plate 3052 is caused to contact with the trigger plate 3054, but the moving and static plate 3052 or the trigger plate 3054 is caused to contact but cannot conduct electricity, so that the information of the key cannot be output, but when the user presses, the first coil 4022, the moving and static plate 3052 and the trigger plate 3054 do not form a passage, so that the conductive metal rod 4021 cannot repel one end of the magnet block 403, and thus the current flows to one end of the magnet block 403 through the conductive metal rod 4021, the rebound rod 4031 is circulated to the click switch 3053, so that the conductive metal rod 4021, the magnet block 403, the click switch 3053 and the second dense coil 4023 form a passage, key information is output at this time, when the key information is output, the magnet block 403 is instantly sprung out due to the coil of the second dense coil 4023, meanwhile, the magnetism of the conductive metal rod 4021 is instantly disappeared, one end of the rigid plastic of the magnet block 403 is impacted to the bottom end of the sounding part 502 of the alarm device 5, meanwhile, the magnet block 403 is restored to an initial state and is adsorbed on the conductive metal rod 4021, after the impact is finished, the key cap 2 is made to emit vibrating sound of the sounding part 502, part of vibration of the vibrating sound can spread to the mechanical shaft 3 and the key cap 2 through the fixing rod 501, and a user instantly senses the vibration of the key cap 2 and the mechanical shaft 3, so that the key of the keyboard is informed of faults and needs to be cleaned or maintained.

Embodiment two differs in that: the conductive metal rod 4021 is connected with the first coil 4022 in series, the other connection mode is unchanged, namely one end of the first coil 4022 is connected with the conductive metal rod 4021, then is connected with the electrode input end of the movable and static plates 3052 in series through the conductive metal rod 4021, the other end of the first coil 4022 is connected with the power input interface of the mechanical shaft 3 in series, the other end of the movable and static plates 3052 is movably connected with the positive electrode input end of the trigger plate 3054, the electrode input end of the inching switch 3053 is electrically connected with the top rebound rod 4031 of the magnet block 403, the magnet block 403 is movably connected with the conductive metal rod 4021, the electrode output end of the inching switch 3053 is electrically connected with the electrode input end of the second dense coil 4023, the electrode output end of the second dense coil 4023 is connected with the trigger plate 3054 in parallel, at this time, when the trigger plate 3054 and the movable and static plates 3052 fail, the coil number of the electromagnet of the spring-open magnet block 403 is the coil number of the first coil 2 plus the coil number of the second dense coil 4023, the spring force of the magnet block 403 is enhanced, or the spring force of the magnet block 403 is reduced, or the whole coil is formed in the mode.

Finally: the foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
