[0027] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In the description of the present application, it should be noted that the terms used here are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] Embodiment 1:

[0030] This embodiment provides a push button switch, including:

[0031] A mounting base 1, wherein a wiring head 2 is provided at the bottom of the mounting base 1;

[0032] A button 3, wherein the button 3 is installed above the mounting base 1;

[0033] A first spring 4, wherein the first spring 4 is axially abutted between the button 3 and the mounting seat 1;

[0034] A transmission assembly, the transmission assembly includes a movable rod 5, a limit seat 6 and a contact assembly, one end of the movable rod 5 is installed at the bottom of the button 3, the limit seat 6 is sleeved on the movable rod 5, and the contact assembly is arranged on the other end of the movable rod 5 for conducting the wiring head 2;

[0035] A second spring 7, wherein the second spring 7 is axially abutted between the movable rod 5 and the mounting seat 1;

[0036] The limiting seat 6 is provided with a first magnetic block 8, and the mounting seat 1 is provided with a second magnetic block 9, and the first magnetic block 8 and the second magnetic block 9 are adsorbed and connected together.

[0037] In the present technical solution, the mounting base 1 includes a socket 101 detachably connected to the bottom, and the terminal head 2 is installed on the socket 101. The movable rod 5 is controlled to move downward by pressing the button 3, and the movable rod 5 drives the limit seat 6 and the contact assembly to move downward. The first magnetic block 8 and the second magnetic block 9 are separated, and the two ends of the contact assembly are respectively abutted against the static contacts of the terminal head 2, so that the two terminal heads 2 are connected to realize the circuit conduction controlled by the switch.

[0038] The downward movement of the button 3 causes the first spring 4 and the second spring 7 to be compressed and generate elastic force. When the user releases the button 3, the elastic force generated by the first spring 4 can push the button 3 upward and drive the movable rod 5 upward. At the same time, the elastic force generated by the second spring 7 can also push the movable rod 5 upward and drive the button 3 upward. Even if one spring has a problem, the button 3 can still complete the reset operation to ensure the reliability and normal operation of the switch. In addition, during the upward movement of the movable rod 5, the first magnetic block 8 approaches the second magnetic block 9, and the second magnetic block 9 will attract the first magnetic block 8. Combined with the elastic force of the double springs, the reset of the button 3 is further accelerated to improve work efficiency.

[0039] Through this structural design, designing a double spring in the switch can prevent the reset function of the button 3 from failing when one of the springs is damaged or fails, ensuring that the switch can be reset normally, effectively enhancing the reliability and safety of the switch; in addition, the elastic force generated by the compression of the double springs and the suction force of the second magnetic block 9 on the first magnetic block 8 can make the button 3 reset more quickly and stably when released, thereby improving practicality.

[0040] Embodiment 2:

[0041] This embodiment provides a push button switch, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] Furthermore, the contact assembly comprises:

[0043] A connecting plate 10, with contact blocks 11 provided on both ends of the connecting plate 10;

[0050] Furthermore, the contact assembly further comprises a third spring 14 , which is sleeved on the end of the movable rod 5 , and two ends of the third spring 14 abut against the connecting plate 10 and the limiting seat 6 respectively.

[0051] In this technical solution, the fixing screw 12 is set through the connecting plate 10, and the connecting plate 10 is located in the limiting groove 13 and can be fixed along the fixing screw 12.

[0052] The third spring 14 is axially abutted between the connecting plate 10 and the limiting seat 6. When the button 3 is in the original state, the two ends of the third spring 14 apply pressure to the limiting seat 6 and the connecting plate 10 respectively, and the limiting plate abuts against the head of the fixing screw 12; when the button 3 is pressed, the movable rod 5 moves downward to drive the connecting plate 10 to move downward, and the contact block 11 on the connecting plate 10 abuts against the static contact point. The third spring 14 is further squeezed to generate elastic force, so that the contact block 11 and the static contact point are kept in close contact, thereby improving the connection stability. Through this structural design, the connection stability between the contact block 11 and the static contact on the terminal 2 is effectively enhanced, so that the connection between the two terminal heads 2 is more stable and reliable when the switch is turned on.
