[0027] Embodiment

[0028] This embodiment provides a ten-pin toggle switch, which includes a base 1 and a cover plate 2 arranged above the base 1. A button 3 is arranged between the base 1 and the cover plate 2. Two contact bridges 4 are arranged below the button 3. The contact bridges 4 are squeezed and arranged between the base 1 and the cover plate 2. The contact bridges 4 are clamped below the button 3. A conductive sheet 5 is arranged below the contact bridges 4. The conductive sheet 5 includes a group of common terminals 51 and at least two groups of output terminals 52. One end of the contact bridge 4 is connected to the common terminal 51, and the other end is connected to any output terminal 52. The contact bridge 4 includes a connection end 41 clamped below the button 3 and elastic ends 42 arranged on both sides of the connection end 41. The elastic ends 42 are bent downward toward the end close to the conductive sheet 5. An extension end 43 inclined upward is further arranged on the side of the elastic end 42 away from the connection end 41.

[0029] The above specific improvement is as follows: Such as Figure 2 and Figure 3As shown, compared with the prior art, the contact bridge 4 includes a connection end 41 closely attached to the bottom of the button 3 and elastic ends 42 arranged on both sides of the connection end 41. The elastic end 42 on one side is connected to the common terminal. When the elastic end 42 on the other end needs to be cut from one output terminal 52 to another output terminal 52, the button 3 moves to the left or right, and the button 3 is pressed downward, thereby squeezing the accommodation space of the contact bridge 4. After the connection end 41 is pressed downward, the elastic ends 42 on both sides are deformed toward one side of the button 3 (that is, upwardly deformed). After the assembly is completed, the contact bridge 4 is extruded and arranged on the base 1. Due to the elasticity of the deformation end itself, the contact state with the conductive sheet 5 is always maintained between the contact bridge 4 and the button 3. Even if the contact bridge 4 is more or less deformed, the elastic ends 42 on both sides can be guaranteed to be in contact with the conductive sheet 5 at all times, thereby reducing the manufacturing accuracy of the contact bridge 4 and improving the product qualification rate. During the gear switching process, when the elastic end 42 is deformed to a certain space, the top position of the extension end 43 will conflict with the lower end surface of the button 3, thereby preventing the contact bridge 4 from further deformation, reducing the deformation degree of the elastic end 42, and avoiding the elastic failure of the elastic end 42, thereby improving the service life of the contact bridge 4.

[0030] On the basis of the above embodiment: the output terminal 52 includes a first output end 53 and a second output end 54 , each of which is provided with a pin 55 , and each of which is connected to a contact bridge 4 at the top.

[0031] The above specific improvements are: Figure 2 As shown, the toggle switch realizes gear adjustment by toggle button 3, wherein a common terminal 51 and four output terminals 52 are provided in the toggle switch. When the gear needs to be switched, it is only necessary to toggle button 3 so that the contact bridge 4 connects to the output terminal 52 at other positions, and conducts electricity through the pins 55 on the first output terminal 53 and the second output terminal 54 on the output terminal 52.

[0032] On the basis of the above embodiment: the lower end surface of the button 3 is provided with a plurality of positioning blocks 6 for positioning the contact bridge 4 , and a card cavity 61 for the contact bridge 4 to be inserted is formed between the positioning blocks 6 and the button 3 .

[0033] On the basis of the above embodiment: the connecting end 41 is provided with a snap-on end 44 on both sides, the button 3 is provided with a limiting cavity 31 on the lower end surface, the snap-on end 44 at one end of the connecting end 41 is snap-on in the cavity 61 , and the snap-on end 44 at the other end is provided in the limiting cavity 31 .

[0034] On the basis of the above embodiment: the opening of the limiting cavity 31 which contacts the clamping end 44 is provided with a guide arc surface 32 for the auxiliary clamping end 44 to be clamped into.

[0035] The above specific improvements are: Figures 3 - 5 As shown, in order to position the contact bridge 4, four positioning blocks 6 are arranged on the lower end surface of the button 3, and the two positioning blocks 6 and the protruding part of the lower end surface of the button 3 surround to form a card cavity 61 for the contact bridge 4 to be inserted into. In order to increase the contact area between the contact bridge 4 and the button 3, card connection ends 44 are arranged on both sides of the connecting end 41, and a limiting cavity 31 is opened on the button 3. The card cavity 61 is arranged between the two positioning blocks 6, and the two card connection ends 44 of the connecting end 41 are respectively inserted into the limiting cavity 31 and the card cavity 61, and the three are interference fit, thereby effectively fixing the position of the contact bridge 4.

[0036] On the basis of the above embodiment: a protrusion 33 is provided on the upper end surface of the button 3, and a slot 34 for the card block 21 to be inserted is surrounded by adjacent protrusions 33, the card block 21 is arranged on the cover plate 2, and a toggle block 35 is also provided above the button 3 to drive the button 3 to move.

[0037] The above specific improvements are: Figure 1 As shown, when the gear is switched, the toggle block 35 needs to be moved. When moving, the block 21 needs to overcome the limit of the protrusion 33 and enter the adjacent protrusion 33. When the gear is switched, the block 21 has a downward squeezing force on the button 3 and the protrusion 33, so that the button 3 squeezes the contact bridge 4, causing the contact bridge 4 to deform, resulting in the separation of its elastic end 42 from the conductive sheet 5. When the block 21 enters the adjacent slot 34, it means that the gear switch is completed, the block 21 loses the external force, and the contact bridge 4 continues to maintain the contact state with the conductive sheet 5 due to its own elastic restoring force, so that the first output terminal 53 and the second output terminal 54 are energized.

[0038] On the basis of the above embodiment: the base 1 is provided with an auxiliary cross bar 11 for assisting the button 3 to move, and an avoidance cavity 12 adapted to the cross bar is formed between the positioning blocks 6 .

[0039] The above specific improvements are: Figure 2 As shown, in order to ensure the smooth movement of the auxiliary button 3, an auxiliary cross bar 11 is provided on the base 1, and the positioning block 6 on the lower end surface of the button 3 forms an avoidance cavity 12 for avoiding the cross bar. After the installation is completed, the positioning block 6 will be located on both sides of the cross bar, so that the limit button 3 can only move laterally, ensuring smooth gear switching.

[0040] On the basis of the above embodiment: a conductive portion 7 is provided between the first output end 53 and the second output end 54 for connecting the two.

[0041] The specific improvements are as follows: Through the setting of the conductive part 7, the first output terminal 53 and the second output terminal 54 can be connected. Thus, no matter whether the first output terminal 53 or the second output terminal 54 is powered on first, it can ensure that the first output terminal 53 and the second output terminal 54 can be powered on synchronously, further improving the qualified rate of the product.

[0042] Obviously, the above embodiments are only examples given for clear illustration and are 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 the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
