[0028] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The invention will now be further described with reference to the accompanying drawings and embodiments:

[0029] Please see Figure 1-8 A toggle switch includes a housing 1, a base plate 2, a push handle 3, and pins 4, wherein the pins 4 are mounted on the base plate 2, such as... Figure 4As shown, the pin 4 includes a vertical insertion part 5, a horizontal bending part 6, and a vertical bending part 7. The vertical insertion part 5, the horizontal bending part 6, and the vertical bending part 7 are integrally bent and formed structures, as shown. Figure 5 As shown, the base plate 2 is provided with a plug-in groove 8 and a fixing groove 9. The vertical plug-in part 5 is inserted into the plug-in groove 8, and the vertical bending part 7 is inserted into the fixing groove 9.

[0030] The pin 4 is provided with a vertical insertion part 5, a horizontal bending part 6 and a vertical bending part 7. The base plate 2 is provided with an insertion groove 8 and a fixing groove 9. The vertical insertion part 5 is inserted into the insertion groove 8 and the vertical bending part 7 is inserted into the fixing groove 9, which can prevent the pin 4 from shaking and improve the stability of the connection between the pin 4 and the base plate 2.

[0031] Furthermore, when the pin 4 is assembled with the base plate 2, it is only necessary to insert the vertical insertion part 5 into the insertion slot 8 and the vertical bending part 7 into the fixing slot 9, which has the advantage of being easy to install.

[0032] In some implementations, such as Figure 4 As shown, the vertical insertion part 5 is provided with a dovetail-shaped limiting part 10 that cooperates with the base plate 2.

[0033] The dovetail-shaped limiting part 10 at the lower end of the vertical insertion part 5 increases the friction between the vertical insertion part 5 of the pin 4 and the base plate 2, thereby improving the connection stability between the pin 4 and the base plate 2.

[0034] In some embodiments, the fixing groove 9 is a closed groove.

[0035] like Figure 5 and Figure 6 As shown, the fixed groove 9 is a closed groove, which hides the vertical bending part 7 of the pin 4 inside the base plate 2, which can play a protective and support role.

[0036] The vertical bend 7 of pin 4 is hidden inside the base plate 2, and the lower end of the vertical insertion part 5 of pin 4 is a dovetail-shaped fork-type fixing method, which can effectively increase the creepage distance between pin 4 and housing 1, and solve the problem of insufficient creepage distance between existing toggle switch pin 4 and housing 1, which leads to leakage safety hazards.

[0037] In some embodiments, the base plate 2 is installed inside the housing 1, the upper surface of the housing 1 is provided with a slot 11, the lower part of the push handle 3 is disposed inside the housing 1, the upper part of the push handle 3 passes through the slot 11 and is located outside the housing 1, and the lower part of the push handle 3 is slidably connected to the housing 1.

[0038] In some embodiments, the base plate 2 is provided with two rows of pins 4 along the sliding direction of the push handle 3, and each row of pins 4 includes a plurality of pins 4.

[0039] In some embodiments, the base plate 2 is provided with a stop plate 12 along the sliding direction of the push handle 3, and the stop plate 12 is provided with a switch stop groove 13.

[0040] In some implementations, such as Figure 7 As shown, the bottom of the push handle 3 is connected to the shift member 14. The shift member 14 cooperates with the switch gear slot 13 for shifting gears. A first elastic member 15 is provided between the bottom of the push handle 3 and the shift member 14. One end of the first elastic member 15 is connected to the push handle 3, and the other end of the first elastic member 15 is connected to the shift member 14.

[0041] In some implementations, such as Figure 8 As shown, the bottom of the push handle 3 is connected to two metal contact pieces 16. The metal contact pieces 16 are located on both sides of the shift member 14. A second elastic member 17 is provided between the bottom of the push handle 3 and the metal contact pieces 16. One end of the second elastic member 17 is connected to the bottom of the push handle 3, and the other end of the second elastic member 17 is connected to the metal contact pieces 16.

[0042] In some embodiments, the first elastic element 15 is a shift spring, and the second elastic element 17 is a contact spring.

[0043] In some embodiments, the shifting element 14 is a spring steel ball.

[0044] The shifting component 14 is a spring steel ball, and the spring steel ball in the push handle 3 cooperates with the switch position slot 13 to make the switch feel better.

[0045] In some implementations, such as Figure 3 As shown, the bottom plate 2 has two ribs 18 at both ends, and the ribs 18 are arranged parallel to the stop plate 12.

[0046] By adding two ribs 18 to the base plate 2, the creepage distance between the pin 4 and the outer casing 1 can be further increased, so as to achieve high current and high voltage operation in a small volume.

[0047] In some embodiments, the base plate 2, the stop plate 12, and the rib 18 are integrally injection molded.

[0048] In some implementations, such as Figure 2 and Figure 3 As shown, the outer shell 1 is provided with a connecting part 19, the bottom plate 2 is provided with a connecting groove 20 that cooperates with the connecting part 19, and the connecting part 19 is connected to a fixing part 21 for fixing the bottom plate 2.

[0049] The outer shell 1 is provided with a connecting part 19, and the base plate 2 is provided with a connecting groove 20 that mates with the connecting part 19. The connecting part 19 is connected to a fixing part 21 for fixing the base plate 2. During installation, the connecting part 19 of the outer shell 1 is inserted into the connecting groove 20 of the base plate 2, and the base plate 2 is limited and fixed by the fixing part 21, which improves the stability of the connection between the outer shell 1 and the base plate 2.

[0050] In some embodiments, the outer casing 1 is made of metal.

[0051] By using metal material for the outer casing 1, it has the advantage of smaller size, can carry large current and withstand high voltage, and solves the problems of low voltage resistance and easy overheating and deformation when encountering large current in traditional plastic casing 1.

[0052] The main functions of this utility model are:

[0053] This invention features a pin with a vertical insertion part, a horizontal bending part, and a vertical bending part. The base plate has an insertion groove and a fixing groove. The vertical insertion part is inserted into the insertion groove, and the vertical bending part is inserted into the fixing groove, preventing pin wobbling and improving the stability of the connection between the pin and the base plate. A dovetail-shaped limiting part at the lower end of the vertical insertion part increases the friction between the pin and the base plate, further improving the connection stability. The fixing groove, being a closed groove, conceals the vertical bending part of the pin within the base plate, providing protection and support. The concealment of the vertical bending part within the base plate, combined with the dovetail-shaped forked fixing method at the lower end of the vertical insertion part, effectively increases the creepage distance between the pin and the housing, solving the problem of insufficient creepage distance in existing toggle switches, which can lead to leakage safety hazards.
