[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1-4 As shown, this utility model provides an electromagnetic switch, including a housing 5, a button base 7 mounted on the surface of the housing 5, a buckle 11 mounted on both sides of the housing 5, a white button 1, a black button 3 and a transparent lampshade 2 mounted on the button base 7, a spring 8 disposed inside the button base 7, the spring 8 being disposed one-to-one with the white button 1 and the black button 3, a contact component 12 disposed inside the housing 5, the white button 1 and the black button 3 being close to the contact component 12, an electromagnetic device 10 disposed inside the housing 5, a circuit board disposed inside the housing 5, an indicator light component 9 disposed on the button base 7, the indicator light component 9 being electrically connected to the circuit board, and a terminal insert 4 disposed at the bottom of the housing 5.

[0025] As one embodiment of this utility model, one end of the buckle 11 is fixedly connected to the bottom of the button seat 7, and the other end of the buckle 11 is connected to the outer shell 5. The side of the buckle 11 facing away from the outer shell 5 is a convex surface.

[0026] In one embodiment of this utility model, the bottoms of the white button 1 and the black button 3 extend into the button base 7. The bottoms of the white button 1 and the black button 3 are provided with stationary contacts, which are matched one-to-one with the moving contacts on the contact assembly 12.

[0027] In one embodiment of this utility model, the electromagnetic device 10 is installed at the bottom of the housing 5 and is located below the contact assembly 12. The electromagnetic device 10 includes an iron core and a coil.

[0028] In one embodiment of this utility model, one end of the terminal insert 4 extends into the housing 5, and the terminal insert 4 is electrically connected to the electromagnetic device 10.

[0029] In one embodiment of this utility model, spring 8 is respectively disposed at the bottom of white button 1 and black button 3.

[0030] As one embodiment of this utility model, a waterproof pad 6 is installed at the connection between the button base 7 and the outer shell 5.

[0031] Specific working principle:

[0032] When the circuit needs to be connected, the voltage change at the power supply terminal is transmitted to the indicator light assembly 9 through the circuit board, causing it to light up. The light shines through the transparent lampshade 2 to visually inform the user that the electromagnetic switch has been successfully powered on.

[0033] Then press down on the white button 1 with your finger, and the white button 1 moves downward against the elastic force of the spring 8.

[0034] During this process, the white button 1 drives the internal contact component 12 of the button base to operate. The contact component 12 is connected to the control terminal of the electromagnetic device 10, thereby triggering the coil of the electromagnetic device 10 to be energized.

[0035] As current flows through the coil of the electromagnetic device 10, the coil generates a strong magnetic field, causing the internal iron core to shift under the influence of electromagnetic force. This displacement pushes the connected moving contact to tightly engage with the stationary contact, completing the circuit connection. At this point, the power supply circuit for the external device is activated, and the device begins to operate normally.

[0036] When the circuit needs to be disconnected, press the black button 3. The black button 3 also overcomes the resistance of the spring 8 and presses down, causing the contact component 12 inside the button holder to move in the opposite direction. This action cuts off the power supply to the coil of the electromagnetic device 10. The coil's magnetic field quickly disappears, and the iron core returns to its initial position under the action of the return spring or other reset mechanism. The moving contact connected to it also separates from the stationary contact, thus disconnecting the circuit. The power supply to the external device is cut off, and it stops working. The indicator light component 9 remains constantly lit because there is voltage at the power supply terminal; it goes out when the voltage at the power supply terminal fails.

[0037] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
