Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch technology, specifically to a toggle switch. Background Technology
[0002] A toggle switch connects or disconnects a circuit by pushing a lever, thereby switching the circuit. Currently, most toggle switches adopt a non-short-circuit structure design of "break first, then connect," meaning that the moving contact completely separates from the original stationary contact during the switching process before making contact with the new stationary contact. Therefore, existing products cannot meet users' control function requirements. Thus, there is an urgent need to design and manufacture a miniaturized toggle switch with a "short-circuit" function. Utility Model Content
[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect that the toggle switch in the prior art does not have an instantaneous short-circuit function, thereby providing a toggle switch with an instantaneous short-circuit function.
[0004] Therefore, this utility model provides a toggle switch, including a switch housing, contact terminals, and a contact bridge. There is at least one set of contact terminals, including a common terminal and a row of working terminals disposed on one side of the common terminal. The row of working terminals is spaced apart along the moving direction of the contact bridge assembly. Each working terminal has a contact segment that contacts the contact bridge and a pin segment extending out of the switch housing. The width of the contact segment is D1, and the distance between two adjacent contact segments is D2. There is at least one contact bridge, which is movably installed inside the switch housing by a toggle element and can communicate or disconnect from the contact terminals. The contact bridge has a first contact foot and a second contact foot disposed on its two sides. The first contact foot has a first moving contact and a second moving contact spaced apart along the moving direction of the contact bridge. The distance between the first moving contact and the second moving contact is D3, wherein D3 is less than the width D1 of any contact segment and greater than the distance D2 between any two adjacent contact segments. When the contact bridge moves, both the first moving contact and the second moving contact switch between multiple working terminals, and the second contact foot slides in contact with the common terminal.
[0005] A row of working terminals is provided on both sides of the common terminal. The second contact foot has a third moving contact and a fourth moving contact that are spaced apart along the moving direction of the contact bridge. The distance between the third moving contact and the fourth moving contact is D4, wherein D4 is less than the width D1 of any of the contact segments and greater than the distance D2 between any two adjacent contact segments. When the third moving contact and the fourth moving contact switch between multiple working terminals, the first contact foot slides in contact with the common terminal.
[0006] The two rows of working terminals are symmetrically distributed on both sides of the common terminal.
[0007] There are two sets of contact terminals, which are arranged side by side, and the pin segments of the two sets of contact terminals extend from the two sides of the switch housing respectively. The switch housing is provided with two contact bridges that correspond to the two sets of contact terminals.
[0008] Both contact bridges are driven by the same toggle element.
[0009] The contact bridge has an arched protrusion located in its middle, and the actuating member is formed with a groove adapted to the arched protrusion.
[0010] The technical solution of this utility model has the following advantages:
[0011] 1. The toggle switch provided by this utility model includes a switch housing, contact terminals, and a contact bridge. The first contact foot has a first moving contact and a second moving contact that are spaced apart along the moving direction of the contact bridge. The distance between the first moving contact and the second moving contact is D3, wherein D3 is less than the width D1 of any contact segment and greater than the distance D2 between any two adjacent contact segments. In this way, when the first moving contact is about to separate from the previous working terminal, the second moving contact has already made contact with the adjacent next working terminal, thereby realizing the "short circuit" function. Furthermore, since both the first moving contact and the second moving contact are located on the contact bridge, the width of the contact bridge is relatively narrow, which meets the requirement of miniaturization of the switch.
[0012] 2. The toggle switch provided by this utility model has a row of working terminals on both sides of the common terminal. The second contact foot has a third moving contact and a fourth moving contact that are spaced apart along the moving direction of the contact bridge. The distance between the third moving contact and the fourth moving contact is D4, wherein D4 is less than the width D1 of any contact segment and greater than the distance D2 between any two adjacent contact segments. When the third moving contact and the fourth moving contact switch between multiple working terminals, they can also achieve the function of instantaneous short circuit. Attached Figure Description

[0025] Example
[0026] This embodiment provides a toggle switch, such as Figure 1 As shown, it includes a switch housing 1, contact terminals 2, contact bridge 4, and a toggle element 5.
[0027] There are two sets of contact terminals 2, arranged side by side, with the lead segments 24 of the two sets of contact terminals 2 extending from opposite sides of the switch housing 1. Each set of contact terminals 2 includes a common terminal 21 and a row of working terminals 22 located on one side of the common terminal 21. The row of working terminals 22 is spaced apart along the moving direction of the contact bridge assembly. Each working terminal 22 has a contact segment 23 that contacts the contact bridge 4 and a lead segment 24 extending out of the switch housing 1. The width of the contact segment 23 is D1, and the distance between two adjacent contact segments 23 is D2. It should be noted that the contact terminals 2 can also be a set, with one terminal corresponding to the contact bridge 4.
[0028] As a possible implementation, a row of working terminals 22 is provided on each side of the common terminal 21. In this embodiment, the two rows of working terminals 22 are symmetrically distributed on both sides of the common terminal 21.
[0029] There are two contact bridges 4. The contact bridges 4 are movably installed within the switch housing 1, driven by a toggle element 5, and can communicate with or disconnect from the contact terminals 2. Each contact bridge 4 has a first contact foot 41 and a second contact foot 42 located on either side. The first contact foot 41 has a first moving contact 411 and a second moving contact 412 spaced apart along the moving direction of the contact bridge 4. The distance between the first moving contact 411 and the second moving contact 412 is D3, where D3 is less than the width D1 of any contact segment 23 and greater than the distance D2 between any two adjacent contact segments 23. When the contact bridge 4 moves, both the first moving contact 411 and the second moving contact 412 switch between multiple working terminals 22, and the second contact foot 42 slides in contact with the common terminal 21. Figure 3 and Figure 4 As shown, in the initial state, the first moving contact 411 and the second moving contact 412 of the contact bridge 4 are both in contact with the same working terminal 22. During the process of the contact bridge 4 moving to the right to switch to the next position, as... Figure 5 As shown, when the first moving contact 411 is about to separate from the leftmost working terminal (that is, the first moving contact 411 is still in contact with the working terminal), the second moving contact 412 has already made contact with the other adjacent working terminal. In this way, the common terminal 21 is connected to the two adjacent working terminals at the same time, realizing the function of instantaneous short circuit.
[0030] like Figure 6 As shown, the second contact foot 42 has a third moving contact 423 and a fourth moving contact 424 spaced apart along the moving direction of the contact bridge 4. The distance between the third moving contact 423 and the fourth moving contact 424 is D4, wherein D4 is less than the width D1 of any of the contact segments 23 and greater than the distance D2 between any two adjacent contact segments 23. When the third moving contact 423 and the fourth moving contact 424 switch between multiple working terminals 22, the first contact foot 41 slides in contact with the common terminal 21.
[0031] In this embodiment, the two contact bridges 4 are driven by the same actuating element 5, such as... Figure 2 As shown, the contact bridge 4 has an arched protrusion 43 located in its middle, and the actuating member 5 is formed with a groove 51 that matches the arched protrusion 43.
[0032] The toggle switch provided by this utility model includes a switch housing 1, contact terminals 2, and a contact bridge 4. The contact bridge 4 has a first contact foot 41 and a second contact foot 42 respectively disposed on both sides. The first contact foot 41 has a first moving contact 411 and a second moving contact 412 spaced apart along the moving direction of the contact bridge 4. The distance between the first moving contact 411 and the second moving contact 412 is D3, wherein D3 is less than the width D1 of any contact segment 23 and greater than the distance D2 between any two adjacent contact segments 23. In this way, when the first moving contact 411 is about to separate from the previous working terminal 22, the second moving contact 412 has already made contact with the adjacent next working terminal 22, thereby realizing the "short circuit" function. Since the first moving contact 411 and the second moving contact 412 are both disposed on the contact bridge 4, the width of the contact bridge is relatively narrow, which meets the requirements of switch miniaturization.
[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
