Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.
[0037] like Figures 1-5As shown, an intelligent switch capable of setting different numbers of buttons includes an external base 6 and an intelligent switch device connected to the external base 6, wherein the intelligent switch device includes a switch housing 1, wherein a circuit board 2 having an information storage function and capable of receiving control instructions and outputting electrical equipment control signals according to the input control instructions is provided in the switch housing 1, a display screen 3 connected to the circuit board 2 is provided on the top surface of the switch housing 1, a plurality of push switches 4 for inputting different electrical equipment control instructions to the circuit board 2 are provided on the switch housing 1 near the side of the display screen 3, a plurality of display areas 31 for displaying different electrical equipment information according to the stored information are provided on the display screen 3, and one push switch 4 corresponds to one display area 31, and a keypad 5 for pressing and triggering the push switch 4 is provided on the top surface of the switch housing 1.
[0038] In actual use, the external base 6 is first connected to each electrical device, wherein a relay is provided in the external base 6. By controlling the on and off operation of the relay, the operation of the corresponding electrical device is controlled. Then, the stored information is input into the circuit board 2 in the smart switch. The stored information includes information such as the name of the electrical device displayed in the area 31 of the display screen 3, the operating status of the electrical device, and the control signal information corresponding to the control instruction input by the push switch 4. After the stored information is input, the smart switch is plugged and installed on the external base 6 to connect the smart switch to the external base 6. During use, the display screen 3 is divided into multiple display areas 31 and the information of the electrical device controlled by the corresponding push switch 4 is displayed in each display area 31 for prompting. When the user needs to turn on or off or adjust one of the electrical devices, the corresponding push switch 4 is triggered by pressing the keypad 5 to input the electrical device control instruction to the circuit board 2. The circuit board 2 controls the operation of the relay in the external base 6 according to the input electrical device control instruction, thereby outputting the corresponding control signal to the corresponding electrical device, thereby controlling the electrical device to perform the corresponding operation and feedback the real-time working status of the electrical device on the corresponding display area 31.
[0039] like Figures 1-5 As shown, preferably, the number of display areas 31 of the display screen 3 is the same as the number of push switches 4; preferably, the display screen 3 is a bar display screen and is horizontally arranged in the middle of the top surface of the switch housing 1, and the push switches 4 are arranged on the top surface of the switch housing 1 above and / or below the display screen 3. The push switches 4 and the adjacent display areas 31 of the display screen 3 correspond to displaying the information of the electrical devices. When in use, 1-4 push switches 4 can be set to control 1-4 electrical devices according to actual needs; this case takes the control of three electrical devices as an example, such as Figures 3-5As shown, a push switch 4 is provided on the upper side of the display screen 3, and the upper keypad 5 is pressed individually to control the upper push switch 4. At the same time, two push switches 4 are provided on the lower side of the display screen 3, and the two ends of the lower keypad 5 are pressed to control the two push switches 4 on the lower side, thereby realizing the separate control of three electrical devices. At the same time, the display screen 3 is divided into three display areas 31 according to the layout of the push switches 4, so that the display area 31 displays information of the electrical devices controlled by the adjacent push switches 4, such as Figure 3 As shown, the upper half of display screen 3 displays the name and operating status of the corresponding electrical device controlled by upper push switch 4, while the lower half of display screen 3, divided into left and right portions, displays the name and operating status of the corresponding electrical devices controlled by adjacent push switches 4. This implements the function of indicating the pressed position of keypad 5 and the electrical device controlled by the corresponding push switch 4. Push switches 4 are microswitches, and inputting control commands to the control circuit through the microswitches can reduce electrical interference between input commands from the push switches and improve the accuracy of control command input.
[0040] For example, the smart switch can control the operation of electrical equipment such as the living room main light, TV wall light and wall light. The external base 6 is connected to the living room main light, TV wall light and wall light respectively, and then the circuit board 2 of the smart switch is pre-set with the electrical equipment name information, working status information, display area and control signal of the living room main light, TV wall light and wall light respectively. Then the smart switch is installed on the external base 6. When working, the display screen 3 is divided into three display areas, and the name information and working status information of the living room main light, TV wall light, wall light, etc. are displayed respectively. When the user needs to adjust the living room main light, press the keypad 5 adjacent to the display area displaying the name information of the living room main light. Pressing the keypad 5 triggers the press switch 4, and inputs the control instruction to the circuit board 2. The circuit board 2 outputs the control signal to the living room main light through the external base 6 according to the input control instruction, and controls the living room main hall to perform the corresponding work.
[0041] like Figures 3-4As shown, preferably, a shell through hole 11, a shell bayonet 12 and a reset elastic member 13 for resetting the pressed position of the key panel 5 are provided on the top surface of the switch shell 1, the push switch 4 is arranged in the shell through hole 11, and a key panel hook 51 passing through the shell bayonet 12, a key panel pressing protrusion 52 for pressing and triggering the push switch 4, and a key panel reset protrusion 53 connected to the reset elastic member 13 are provided on the bottom surface of the key panel 5. The shell bayonet 12 cooperates with the keypad hook 51 to prevent the keypad 5 from falling off the switch shell 1, and at the same time enables relative pressing movement between the keypad 5 and the switch shell 1; when the keypad 5 is pressed, the keypad pressing protrusion 52 presses down to trigger the pressing end of the press switch 4, thereby causing the press switch 4 to input a control instruction to the circuit board 2; when the keypad 5 is pressed, the keypad reset protrusion 53 presses down the reset elastic member 13 provided on the switch shell 1, causing the reset elastic member 13 to deform. After pressing the keypad 5, the reset elastic member 13 resets upward, thereby driving the keypad 5 to move upward and reset through the keypad reset protrusion 53, so that the keypad pressing protrusion 52 is separated from the press switch 4.
[0042] like Figures 3-5 As shown, preferably, two positioning through holes 14 are provided on the top surface of the switch housing 1, and two key panel positioning protrusions 55 are provided on the bottom surface of the key panel 5, which are respectively positioned with the positioning through holes 14 to limit the pressing direction of the key panel 5, so that the press switch 4 on the lower side can be accurately triggered when the key panel 5 is pressed down; a housing top surface groove 15 is provided at the edge position of the top surface of the switch housing 1, and a key panel convex ring 56 is provided at the edge position of the bottom surface of the key panel 5 to cooperate with the housing top surface groove 15, so that the key panel 5 can accurately trigger the press switch 4 on the lower side.

The reset elastic member 13 is disposed within the housing through-holes 11 and contact the keypad reset bumps 53. A keypad fulcrum 54 is provided in the middle of the bottom surface of the keypad 5 to contact the top surface of the switch housing 1. After the keypad 5 is mounted on the switch housing 1, the keypad fulcrum 54 contacts the inner side surface of the switch housing 1, enabling the keypad 5 to function as a seesaw. When one end of the keypad 5 is pressed to trigger the lower push switch 4, the other end of the keypad 5 is lifted up and no longer contacts the lower push switch 4 under the action of the keypad fulcrum 54, thereby realizing the function of a single keypad 5 controlling two push switches 4. Similarly, after the pressing is released, the keypad 5 is reset by being pressed at one end under the action of the reset elastic member 13.
[0044] As Figures 3-5 shown, preferably, when the key plate 5 only needs to press the control of a press switch 4, the key plate 5 is a single-touch key plate, the key plate press block 52 is arranged in the middle of the bottom surface of the key plate 5, and the key plate reset block 53 is arranged at both ends of the bottom surface of the key plate 5.

The press switch 4 is arranged in the middle shell through hole 11 and in contact with the key plate press block 52. The reset elastic member 13 is arranged in the two end shell through holes 11 and in contact with the key plate reset block 53. The press position of the single-touch key plate is generally arranged in the middle. The press switch 4 is triggered by pressing the middle position of the single-touch key plate. Similarly, after the press is released, the key plate 5 is reset at one end under the action of the reset elastic member 13.
[0045] As Figures 1-15 shown, the circuit board 2 is provided with an intelligent switch external terminal 21, a power supply circuit 22 for power supply, and a control circuit 23 with storage information function and capable of receiving control instructions and outputting power equipment control signals according to the input control instructions.

The power supply input end of the power supply circuit 22, the power equipment control signal output end of the control circuit 23, and the detection end of the zero-crossing detection circuit 27 are respectively connected with the intelligent switch external terminal 21.
[0046] Before use, the number of electrical devices is controlled according to the actual usage scenario, and the stored information such as the name of the electrical device, the working status of the electrical device, and the control signal corresponding to the control instruction input by the press switch 4 is input into the control circuit 23 of the circuit board 2; when the smart switch is installed on the external base 6, the external terminal 21 of the smart switch is connected to the connection terminal of the external base 6 to realize the power supply to the circuit board 2 in the smart switch, the zero-crossing detection of the input power supply, and the input of the control signal to the external base 6; when in use, the control circuit 23 controls the display of the display screen 3 through the backlight circuit 25 and the display interface circuit 24, and divides the display screen 3 into multiple display areas 31 according to the preset storage information, and displays the information of the electrical device controlled by the adjacent press switch 4 on the display area 31 for prompting; when the user needs to adjust the electrical device, press the keypad 5 to trigger the corresponding press switch 4 on the lower side, and the press switch 4 is triggered to output the control instruction to the control circuit 23, and the control circuit 23 outputs the control signal to the outside through the external terminal 21 of the smart switch according to the control instruction. During use, when the display screen 3 is in working state, the backlight circuit 25 controls the display screen 3 to display in 100% high brightness state. When the display screen 3 is in sleep state, the backlight circuit 25 controls the display screen 3 to display in 10% low brightness state, which serves to prompt the position of the smart switch.
