The pressing member 3 is provided with a pressing projection 31, the base 1 is provided with a guiding inclined plane 11, the upper cover 2 is provided with an elastic member 6, and one end of the elastic member 6 is positioned below the pressing projection 31 and above the guiding inclined plane 11.

In the present embodiment, the elastic member 6 is a torsion spring 6', as shown in fig. 4, the torsion spring 6' includes a spring body 61, a spring portion 62 connected to one end of the spring body 61, and a connecting portion 63 connected to the other end of the spring body 61, wherein the spring body 61 is disposed in the upper cover 2, the spring portion 62 extends to a position below the pressing protrusion 31 and above the guiding inclined surface 11, and the connecting portion 63 is inserted into the upper cover 2.

As shown in fig. 2 and 3, in the installation and position limitation manner of the torsion spring 6', in the embodiment, the lower end of the upper cover 2 is provided with an insertion groove 22 for the spring body 61 to be inserted into, and an opening 221 for the elastic portion 62 to penetrate out is formed on the side of the insertion groove 22, and meanwhile, a position limitation portion 23 is arranged at the lower end of the upper cover 2 and above the elastic portion 62. Meanwhile, as shown in fig. 7, a support block 12 is provided on the base 1 just below the insertion groove 22. After the upper cover 2 is covered on the base 1, the spring body 61 of the torsion spring 6 'is inserted into the insertion groove 22, and the spring body 61 is supported by the support block 12, thereby limiting the torsion spring 6' in the insertion groove 22.

In the present embodiment, the pressing member 3 is a guide core 3', as shown in fig. 4, the pressing protrusion 31 is disposed on the side of the guide core 3', and the end of the pressing protrusion 31 has an inclined surface 311.

In the process of pressing the guide core 3' downwards, the pressing lug 31 on the guide core 3' moves downwards along with the downward movement of the pressing lug 31, the elastic part 62 of the torsion spring 6' is pressed downwards by the pressing lug 31, the elastic part 62 moves downwards, and when the elastic part 62 moves downwards to touch the guide inclined plane 11 on the base 1, the elastic part slides outwards along the guide inclined plane 11 until the elastic part 62 is separated from the pressing lug 31, and at the moment, a hand can feel that the pressing force is obviously reduced, so that the hand feeling is generated; meanwhile, the pressing bump 31 is rebounded and reset, and is knocked on the upper cover 2 to generate sound.

In order to enable the elastic portion 62 of the torsion spring 6' to be more accurately knocked on the upper cover 2 to generate sound, as shown in fig. 4, 5 and 7, a stopper 7 located between the pressing member 3 and the guiding inclined surface 11 is disposed in the accommodating cavity in the embodiment. Specifically, as to the arrangement manner of the stopper 7, the stopper 7 of the present embodiment is arranged on the base 1 or the upper cover 2. When the pressing bump 31 rebounds and returns, the pressing bump not only strikes the upper cover 2 to generate sound, but also strikes the stop 7 to generate sound.

In this embodiment, as shown in fig. 6 and 7, a guide post 13 protrudes upward from the bottom of the base 1, the guide post 13 is provided with a guide hole 131, the lower end of the pressing member 3 is provided with a positioning post 32 inserted into the guide hole 131, and the spring 4' is sleeved on the outer periphery of the guide post 13 and the positioning post 32.

In this embodiment, the key switch may adopt a moving-static sheet mechanical conduction mode or a magnetic conduction mode to realize the conduction and disconnection functions.

When the key switch adopts a moving-fixed sheet mechanical conduction mode, as shown in fig. 1 and fig. 6, the conduction assembly 5 includes a fixed sheet 51 and a moving sheet 52, a pressing guide block 33 located on the side of the moving sheet 52 is disposed on the side of the pressing member 3, a slot 14 into which the fixed sheet 51 and the moving sheet 52 are inserted is formed on the base 1, and a movable slot 15 into which the pressing member 3 moves up and down is formed on the base 1 and at the periphery of the guide post 13. When the guide core 3' is not pressed, the movable piece 52 is pushed outwards by the pressing guide block 33, so that the movable contact on the movable piece 52 is separated from the fixed contact on the fixed piece 51, and the key switch is in an off state; when the guide core 3 'is pressed downwards, the spring 4' is extruded, meanwhile, the pressing guide block 33 is separated from the movable piece 52, the pushing force on the movable piece 52 is released, the movable piece 52 rebounds and resets, the movable contact on the movable piece 52 is contacted with the fixed contact on the fixed piece 51, and the key switch is conducted; when the pressing of the guide core 3' is released, the elastic restoring force of the spring 4' restores the guide core 3', so that the pressing guide block 33 pushes the movable piece 52 outwards, the movable contact on the movable piece 52 is separated from the fixed contact on the fixed piece 51, and the key switch is restored to the off state.

When the key switch adopts a magnetic conduction mode, as shown in fig. 8, the conduction assembly 5 includes a magnet 53 disposed on the conductive core 3 'and a magnetic sensor 54 disposed on the PCB 10 and located below the magnet 53, wherein the magnet 53 can be embedded in the conductive core 3', and the magnetic sensor 54 can be any one of a magnetic sensing chip, a magnetic sensing resistor and a magnetic sensing capacitor.

When the guide core 3 'is pressed downwards, the magnet 53 on the guide core 3' moves downwards, and the magnetic field generated by the magnet 53 makes the magnetic inductor 54 generate a wave band, so that the magnetic inductor 54 sends out a signal, and the key switch conduction function is realized. When the pressing on the guide core 3' is released, the elastic restoring force of the spring 4' causes the guide core 3' to move upwards for resetting, the magnet 53 moves upwards, the magnetic field generated by the magnet 53 changes or disappears, the signal sent by the magnetic inductor 54 also changes or disappears, and the key switch off function is realized. That is, the magnetic sensor 54 senses and sends out the signal to determine the on/off of the key switch.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are all within the protection scope of the present invention.
