[0025] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a waterproof rocker switch 100. The waterproof rocker switch 100 includes a switch housing 1 and a button assembly 3. Two lower contacts 11 are fixedly installed on both sides of the bottom of the switch housing 1, and a common contact 12 is fixedly installed between the two lower contacts 11 on the same side. Figure 4 and Figure 6 As shown, a through hole a is provided at the bottom of the switch housing 1, and the wire 6 outside the switch housing 1 is inserted into the through hole a and riveted to the lower contact 11 and the common contact 12 respectively, and a glue injection cavity A is provided at the through hole a, and a sealant is provided in the glue injection cavity A. In this way, the purpose of waterproofing can be achieved by injecting sealant into the glue injection cavity A.

[0026] A limit groove 13 opening upward is provided in the switch housing 1, and a moving touch plate 2 is clamped on the limit groove 13. The moving touch plate 2 can rotate up and down with the limit groove 13 as a base point (specifically, lugs are provided on both sides of the moving touch plate 2, and the lugs cooperate with the limit groove 13 to limit the moving touch plate 2), and upper contacts 21 are fixedly installed at both ends of the moving touch plate 2, the upper contact 21 corresponds to the lower contact 11, and the middle part of the moving touch plate 2 contacts with the common contact 12; the button assembly 3 includes an upper clamp 31 and a lower clamp 32 buckled together, and pressure rods 321 are provided on both sides of the bottom end of the lower clamp 32, and the bottom end of the pressure rod 321 contacts with the moving touch plate 2; the upper clamp 31 is rotatably connected to the switch housing 1.

[0027] The waterproof rocker switch 100 provided by the utility model has the advantages that: a switch waterproof structure is provided at the bottom of the switch housing 1, specifically, a glue injection cavity A is provided at the outlet hole a of the wire 6, and the gap between the wire 6 and the outlet hole a can be sealed by filling the glue injection cavity A with sealant. When the push button assembly 3 swings, the pressure rod 321 slides relatively on the moving touch plate 2 and drives the moving touch plate 2 to swing, so that the upper contact at the corresponding end of the moving touch plate 2 contacts the lower contact at the corresponding position, thereby conducting the corresponding circuit.

[0028] Furthermore, the bottom of the injection cavity A has an opening, and the sealant is injected into the injection cavity A from the bottom opening during injection. A bottom cover plate 7 is provided on the bottom surface of the switch housing 1, and a boss 71 abutting against the edge of the injection cavity A and a through hole for the wire to pass through are provided on the bottom cover plate 7. By providing the bottom cover plate 7, the sealant can be shielded and protected from being damaged.

[0029] In some embodiments, Figure 1-Figure 3 As shown, the upper clamp 31 extends out of the upper end of the switch housing 1, and a sealing rubber sleeve 4 is sleeved on the outer periphery of the upper clamp 31. A pressing frame 5 is buckled on the upper end of the switch housing 1, and the pressing frame 5 presses the bottom periphery of the sealing rubber sleeve 4 to the upper end of the switch housing 1. It can effectively prevent water or dust from penetrating from the joint between the button assembly 3 and the switch housing 1. Further, in order to achieve the purpose of waterproofing and dustproofing, a button cover plate 33 is buckled on the upper end of the upper clamp 31, and the button cover plate 33 presses the upper periphery of the sealing rubber sleeve 4 to the upper end of the upper clamp 31. Specifically, in order to adapt to the activity of the button assembly, the sealing rubber sleeve 4 is arranged in a stacked fold shape, thereby increasing the activity margin of the sealing rubber sleeve 4.

[0030] In some embodiments, Figure 5 As shown, a cylindrical cavity 323 is formed downward on the bottom end surface of the lower clamp 32, and a pressure spring 322 and a pressure rod 321 are arranged in the cylindrical cavity 323. The pressure spring 322 provides a downward elastic force for the pressure rod 321, so that the lower end of the pressure rod 321 always abuts against the movable touch plate 2.

[0031] In some embodiments, Figure 3 As shown, the waterproof rocker switch 100 also includes a lamp bead 8, which is fixedly mounted in the middle of an inner cavity formed by an upper clamp 31 and a lower clamp 32. The lamp foot of the lamp bead 8 is connected in series with the moving touch plate 2 through a pressure rod 321 and a pressure spring 322, thereby supplying power to the lamp bead 8, and the upper end of the pressure spring 232 is in contact with the lamp foot; the pressure rod 321 and the pressure spring 232 are both made of conductive metal.

[0032] In some embodiments, Figure 5 As shown, a stop plate 324 is fixedly provided at the bottom edge of the lower clamp 32. When the lower clamp 32 and the upper clamp 31 are assembled in place, the stop plate 324 abuts against the lower edge of the upper clamp 31 to play a role of stopping and limiting.

[0033] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
