[0028] In this embodiment, by cooperating with the contactless optical display controller 5 and the fixed panel 7, people can operate the floating real image button 6 of the display interface to start the contactless optical display controller 5 and control the on and off of the high-voltage power supply, thereby realizing human-computer interaction between people and the contactless high-voltage control switch. Moreover, contactless operation is safer and cleaner, and avoids cross-infection of infectious diseases.

[0029] In detail, when a person touches the floating real image button 6 on the display interface, the optical sensor detects the operation signal of the floating real image button 6 on the display interface and feeds back the signal to the contactless optical display controller 5. The contactless optical display controller 5 controls the high-voltage controller 2 to turn on the power supply of the high-voltage controller 2. Then, when a person touches the floating real image button 6 on the display interface, the optical sensor detects the operation signal of the floating real image button 6 on the display interface and feeds back the signal to the contactless optical display controller 5. The contactless optical display controller 5 controls the high-voltage controller 2 to turn off the power supply of the high-voltage controller 2, thereby realizing the on-off control of the high-voltage power supply by the floating real image button on the interface.

[0030] Further, as shown in Figures 2-5, the fixed steel plate 4 is a rectangular frame structure, and the high-voltage controller 2 is installed inside the fixed steel plate 4 through a supporting plate to control the on and off of the 250V power supply. The low-voltage controller 3 is installed on the supporting plate to provide a low-voltage power supply to the contactless optical display controller 5.

[0031] Further, as shown in Figures 2-5, the fixed steel plate 4 is arranged on the outer wall of the port of the base 1 through a sleeve frame 41. A limit block 11 and a stop block 12 are respectively provided on the outer wall of the port of the base 1. The limit block 11 and the stop block 12 cooperate to limit the position of the sleeve frame 41. A limit hole 42 adapted to the stop block 12 is opened on the sleeve frame 41.

[0032] The clamping member includes a clamping block 71 provided at the edge of the fixed panel 7 and a clamping slot 72 provided at the edge of the fixed steel plate 4 .

[0033] In this embodiment, the fixed steel plate 4 and the clamping member cooperate to facilitate the assembly of the control switch, thereby improving the production efficiency of the control switch and increasing the benefits of the enterprise.

The contactless optical display controller 5 is bonded to a fixed panel 7 for detecting the user's operation on the display interface floating real image button 6, and the optical sensor feeds back the detected operation signal to the contactless optical display controller 5.

[0036] It is worth mentioning that the structures and functions of the equivalent negative refractive index optical element, display and optical sensor are all existing technologies and will not be described in detail here. Working process:

[0037] When a person touches the floating real image button 6 on the display interface, the optical sensor detects the operation signal of the floating real image button 6 on the display interface and feeds it back to the contactless optical display controller 5. The contactless optical display controller 5 controls the high-voltage controller 2 to connect or disconnect one power supply of the high-voltage controller 2, thereby realizing the on-off control of the high-voltage power supply by the floating real image button on the interface.
