Most toggle switches have a housing, with contact pieces respectively arranged at both ends of the housing, and pins extending outward from the contacts to the outside of the housing. Two contact bridges are swingably arranged in the housing, and different pins are controlled to be energized by the swing of the contact bridges, thereby realizing gear changes. In some household appliances, the toggle switch is often used to control the power switch or working mode switching of the device. In order to prevent misoperation, the design of the switch needs to ensure that users can clearly know the state of the switch during use, and avoid equipment damage or safety hazards caused by mis-switching. Some structures with a fixed stroke distance between two pins cannot achieve this function. Content of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect that the fixed structure of the stroke distance between two pins in the prior art makes it inapplicable when the switch state needs to be clear, and thus provide a toggle switch with adjustable stroke.

[0004] To this end, the utility model provides a toggle switch with adjustable stroke, which includes a base and a cover plate arranged above the base. A button is arranged between the base and the cover plate, and two contact bridges are arranged below the button. The contact bridges are squeezed and arranged between the base and the cover plate, and are clamped below the button. A conductive sheet is arranged below the contact bridges. The conductive sheet includes a common terminal, a first output terminal arranged on one side of the common terminal, and a second output terminal group arranged on the other side.

[0029] Embodiment

[0030] This embodiment provides a toggle switch with adjustable travel, including a base 1 and a cover plate 2 disposed above the base 1. A button is disposed between the base 1 and the cover plate 2. Two contact bridges 3 are disposed below the button. The contact bridges 3 are squeezed and disposed between the base 1 and the cover plate 2. The contact bridges 3 are clamped below the button. A conductive sheet 4 is disposed below the contact bridges 3. The conductive sheet 4 includes a common terminal 41, a first output terminal 42 disposed on one side of the common terminal 41, and a second output terminal group 43 disposed on the other side. The distance between the common terminal 41 and the first output terminal 42 is greater than the distance between the common terminal 41 and the second output terminal group 43.

[0031] The above specific improvement is as follows: As Figures 1 - 3As shown in the figure, compared with the prior art, for example, if the left side of the common terminal 41 is the first output terminal 42, then the right side is the second output terminal group 43. The gear shift of the second output terminal group 43 can be applied to the switching of the first, second, and third gears. The first output terminal 42 can be used for the switching of the device state on or off. The stroke from the common terminal 41 to the first output terminal 42 is relatively long, which can be applied to the scenario where accidental operation needs to be prevented. And there are multiple terminals in the second output terminal group 43, and the distance between the second output terminal group 43 and the common terminal 41 is relatively short, which can be used in the scenario of gear replacement. In this way, it can better prevent accidental operation in the state of electrical appliance opening and closing during use, and improve the user's product usage experience.

[0032] Based on the above embodiment: The contact bridge 3 includes a connection end 31 clamped below the button and elastic ends 32 arranged on both sides of the connection end 31. One elastic end 32 moves between the common terminal 41 and the first output terminal 42, and the other elastic end 32 moves between the common terminal 41 and the second output terminal group 43. The second output terminal group 43 includes at least two groups of second output terminals 430.

[0033] The above specific improvement is: As Figure 3 shown, the contact bridge 3 is clamped below the button, and the connection end 31 is partially in close contact with the lower end face of the button. The gear shift is driven by the button to drive the contact bridge 3 to move so as to contact the common terminal 41 and different output terminals. One elastic end 32 of the contact bridge 3 moves between the common terminal 41 and the first output terminal 42 to realize the function of the product in the on or off state, and the other elastic end 32 moves between the three second output terminals 430 to realize the gear shift function of the first, second, and third gears.

[0034] Based on the above embodiment: The elastic end 32 is bent downward toward the end close to the conductive sheet 4, and an extension end 33 inclined upward is further provided on the side of the elastic end 32 away from the connection end 31.

[0035] The above-mentioned specific improvement is as follows: when the button moves to the left or right, the button will be pressed downward, thereby squeezing the accommodating space of the contact bridge 3. After the connecting end 31 is pressed downward, the elastic ends 32 on both sides will deform toward one side of the button (that is, deform upward). After the contact bridge 3 is assembled, it is squeezed and arranged between the base 1 and the button. Due to the elasticity of the deformed end itself, it always maintains a contact state with the conductive sheet 4. Even if there is a small amount of deformation of the contact bridge 3, it can ensure that the elastic ends 32 on both sides are always in contact with the conductive sheet 4, thereby reducing the manufacturing accuracy of the contact bridge 3 and improving the product qualification rate. During the gear switching process, when the elastic end 32 is deformed to a certain space, the top position of the extension end 33 will conflict with the lower end surface of the button, thereby preventing the contact bridge 3 from further deformation, reducing the deformation degree of the elastic end 32, and avoiding the elastic failure of the elastic end 32, thereby improving the service life of the contact bridge 3.

[0036] Based on the above embodiment: the first output terminal 42 and the second output terminal 430 both include a first output end 5 and a second output end 51 , each of which is provided with a pin 52 , and each of which is connected to a contact bridge 3 at the top.

[0037] The above-mentioned specific improvements are as follows: the toggle switch realizes gear adjustment by toggling a button, wherein a common terminal 41 and four output terminals (i.e., a first output terminal 42 and three second output terminals 430) are arranged in the toggle switch. When the gear switching is required, only the button needs to be toggled so that the contact bridge 3 connects to the output terminals at other positions, and conducts electricity through the pins 52 on the first output terminal 5 and the second output terminal 51 on the output terminal.

[0038] Based on the above embodiments: Figure 5 As shown, the lower end surface of the button is provided with a plurality of positioning blocks 6 for positioning the contact bridge 3, and a card cavity 61 for the contact bridge 3 to be inserted is formed between the positioning blocks 6 and the button.

[0039] On the basis of the above embodiment: the connecting end 31 is provided with a snap-on end 311 on both sides, the lower end surface of the button is provided with a limiting cavity 7, the snap-on end 311 at one end of the connecting end 31 is snap-on in the clamping cavity 61, and the snap-on end 311 at the other end is provided in the limiting cavity 7.

[0040] The above-mentioned specific improvements are as follows: in order to position the contact bridge 3, four positioning blocks 6 are arranged on the lower end surface of the button, and the two positioning blocks 6 and the protruding part of the lower end surface of the button are surrounded to form a card cavity 61 for the contact bridge 3 to be inserted into. In order to increase the contact area between the contact bridge 3 and the button, card connection ends 311 are arranged on both sides of the connecting end 31, and a limiting cavity 7 is opened on the button. A card cavity 61 is arranged between the two positioning blocks 6, and the two card connection ends 311 of the connecting end 31 are respectively inserted into the limiting cavity 7 and the card cavity 61, and the three are interference fit, thereby effectively fixing the position of the contact bridge 3.

[0041] On the basis of the above embodiment: a protrusion 71 is arranged on the upper end surface of the button, a slot 81 for a card block 8 to be inserted is arranged between adjacent protrusions 71, the card block 8 is arranged on the cover plate 2, and a toggle block 9 is also arranged above the button to drive the button to move.

[0042] The above-mentioned specific improvements are as follows: when switching gears, the toggle block 9 needs to be moved. When moving, the card block 8 needs to overcome the limit of the protrusion 71 and enter the adjacent protrusion 71. When switching gears, the card block 8 has a downward squeezing force on the button and the protrusion 71, so that the button squeezes the contact bridge 3, causing the contact bridge 3 to deform, resulting in its elastic end 32 being separated from the conductive sheet 4. When the card block 8 enters the adjacent card slot 81, it means that the gear switching is completed, and the card block 8 loses the external force, so that the contact bridge 3 continues to maintain the contact state with the conductive sheet 4 due to its own elastic restoring force, thereby realizing the power-on of the first output terminal 5 and the second output terminal 51.

[0043] On the basis of the above embodiment: a shielding film 91 for shielding the block 8 is arranged above the cover plate 2 .

[0044] The above specific improvements are: Figure 4 As shown, by setting the shielding film 91, the position of the block 8 on the cover plate 2 can be covered to prevent water and dust from entering the interior of the button.

[0045] On the basis of the above embodiment: a conductive portion 92 for connecting the first output end 5 and the second output end 51 is provided between the first output end 5 and the second output end 51 .

[0046] The above specific improvements are: Figure 6 As shown, by setting the conductive part 92, the first output terminal 5 and the second output terminal 51 can be connected, so that no matter whether the first output terminal 5 or the second output terminal 51 is powered on first, it can be ensured that the first output terminal 5 and the second output terminal 51 can be powered on synchronously, further improving the qualified rate of the product.

[0047] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this utility model.
