The structural schematic diagram of state.Electronic switch 10 includes pedestal 12, actuated piece 14, magnetic field generation mould group 16, restrains part 18, elastic element
20 and locating part 22.It restrains part 18 to be connected on pedestal 12, the outer outlet body as electronic switch 10.Locating part 22, which is located at, to be restrained
In part 18, to connect pedestal 12 via contained part 18.Electronic switch 10 can be the key switch of any kenel, such as keyboard is with pressing
Key or home-use headlamp switch, therefore the settable keycap 24 in one end of actuated piece 14, the other end of actuated piece 14 is through elasticity member
Part 20 is connected to magnetic field and generates mould group 16；Other elastic element 20 or pedestal 12 may can be attached directly in state sample implementations
On, though the mould group 16 of magnetic field generation at this time slightly offsets from elastic element 20 and still needs to alignment actuated piece 14 to apply effective magnetic repulsion.
22 system of locating part of first embodiment of the invention is cannula structure, and actuated piece 14 is accommodated in limit in a manner of movable
In part 22, as user presses keycap 24, actuated piece 14 just can arbitrarily move between contained part 18 and pedestal 12.At other
Possibility state sample implementation in, locating part 22 ' can be the clamp structure with loose fit characteristic, as shown in figure 3, it is by locating part
22 ' are designed to the pattern of holding shrapnel, and the holding shrapnel is allowed to apply pressure to the side surface of actuated piece 14.The limit of holding shrapnel pattern
Part 22 ' can limit actuated piece 14 and move along predetermined direction relative magnetic field generation mould group 16, it is ensured that the magnetic of magnetic field generation mould group 16
Repulsion can be correctly transmitted on actuated piece 14.In addition, restraining part 18 has stopper section 26；When the elasticity of elastic element 20 is restored
When power drives 14 relative limit part 22 (or locating part 22 ') of actuated piece mobile, actuated piece 14, which advances, can be abutted only after certain stroke
Stopper 26 avoids actuated piece 14 from dropping out contained part 18.
Magnetic field generates mould group 16 and is arranged on pedestal 12.Actuated piece 14 utilizes contained part 18, elastic element 20 and locating part
22 auxiliary connects pedestal 12 in a manner of movable.Actuated piece 14 includes magnet unit 28；Magnetic field generate mould group 16 also have pair
The magnetic force structure 30 answered, such as electromagnetic unit or permanent magnet unit.The magnetic force structure 30 of permanent magnet unit pattern applies magnetic repulsion in magnetic

Second embodiment is slightly different with first embodiment, and the contained part 66 of electronic switch 50 is a shell external form, and
Shell front end has stopper section 68.When the elastic restoring force of elastic element 60 drives actuated piece 56 toward mobile, stopper section outside shell
68 can be used to the correspondence convex block 70 of backstop actuated piece 56, and actuated piece 56 is avoided to drop out contained part 66 completely.Magnetic force structure 62 is forever
When magnetic cell, magnetic field, which generates mould group 54, can generate the magnetic repulsion of fixed value to actuated piece 56.If magnetic force structure 62 is electromagnetism list
Member, the magnitude that adjustment magnetic repulsion can be removed by different input currents is provided；In this way, which magnetic field, which generates mould group 54, to simulate
Different style of writing features.Such as: for electronic switch 50 when executing the application program of brush writing, it is smaller that magnetic field generates the offer of mould group 54
The movable distance of magnetic repulsion, actuated piece 56 becomes larger, and user can just experience softer writing brush style of writing；If electronic switch 50 is held
The application program of row pen writing, magnetic field generate mould group 54 and provide larger magnetic repulsion, and the movable distance of actuated piece 56 reduces, instead
The harder pen style of writing of the user that feeds.
Electronic switch 50 (stylus), can also be according to the dynamics of operation electronic switch 50 while providing force feedback function
Size generates the person's handwriting with the variation of corresponding thickness.Therefore, electronic switch 50 it is another alternative comprising pressure detection device 72 and
Corresponding operation detector 74.Pressure detection device 72 is typically situated close on the locating part 58 of actuated piece 56, is implied that and is passed through limit
Part 58 is arranged in pedestal 52 to obtain power source indirectly.72 system of pressure detection device is according to actuated piece 56 relative between pedestal 52
It is corresponding to obtain the outer force being applied on actuated piece 56 away from variation；Since 56 activity of actuated piece is accommodated in locating part 58, one
As pressure value can be obtained using the relative displacement of actuated piece 56 and locating part 58, right practical application is not limited to this.Operation is detectd
It surveys device 74 and is electrically connected pressure detection device 72, it can be according to the detecting result output control signal of pressure detection device 72, to control outside
Electronic device (such as screen) shows the person's handwriting of corresponding thickness of lines.
Special one is mentioned that, the pressure detection device 72 and operation detector 74 of second embodiment separately may be used on the first implementation
The electronic switch 10 (not being drawn in figure) of example, such as the setting of pressure detection device 72 in the locating part 22 of electronic switch 10 or is arrested
In bundle 18, operation detector 74 is electrically connected pressure detection device 72 to obtain the detecting result of pressure detection device 72, by detecting
The displacement of actuated piece 14 judges that user is light pressure or weight keycap 24, and user's input can be represented under specific operation situation
Different control instructions；In addition, it is corresponding reversed that magnetic field generation mould group 16 can also be driven to provide according to the strength of pressing keycap 24
Feedback force gives actuated piece 14B, and it is to experience suitable force feedback that the application that user can arrange in pairs or groups according to electronic switch 10, which is held,；One
As for, this situation be typically used in operation video game situation, so it is without being limited thereto.
Fig. 6 to Fig. 8 is please referred to, Fig. 6 to Fig. 8 is respectively the structural representation of the pressure detection device 72 of different embodiments of the invention
