The lever cap mates with the lever mounting hole on the top cover and passes through the lever mounting hole on the top cover. The annular boss is located in the annular sealing groove on the annular sealing boss, thereby forming a seal between the annular boss and the annular sealing boss, and between the lever cap and the downlight housing.
[0014] 2. This utility model covers the toggle switch with a dust cap, so that all exposed surfaces of the toggle switch, except for the bottom surface that is in contact with the power board, are covered by the dust cap, thus effectively sealing the gaps of the toggle switch itself.
[0015] 3. This utility model simplifies the structure of the dust cap by making the inner sidewall of the annular sealing groove flush with the outer sidewall of the corresponding lever cap body; and further enhances the seal between the dust cap and the top cover by setting an annular pointed top near the outer sidewall of the annular sealing boss, so that the annular pointed top abuts against the back of the top cover.
[0016] 4. This utility model provides a downwardly oriented avoidance ramp on the upper cover surrounding the upper edge of the lever mounting hole, which makes it easier to operate the toggle switch.
[0017] 5. This utility model increases the strength of the annular sealing boss by increasing the thickness from the bottom wall of the annular sealing groove to the back of the annular sealing boss, making its fit with the toggle switch more stable, especially when the toggle switch is toggled.

[0025] The following describes in detail, with reference to the accompanying drawings, a detailed embodiment of the mounting structure of the toggle switch according to this utility model.
[0026] like Figures 1 to 4 and Figure 6 As shown, the downlight of this utility model includes: a lower shell 4 and an upper cover 1 disposed on the lower shell 4. A heat sink 6, a lamp plate 7, and a lens 8 are sequentially arranged from the inside to the outside of the lower shell 4. A power supply board 5 is disposed on the side of the heat sink 6 facing the upper cover 1. A toggle switch 2 is disposed on the power supply board 5 facing the upper cover 1. Figure 4 and Figure 5As shown, the upper cover 1 has a lever mounting hole 11 corresponding to the lever 21 of the toggle switch 2. The upper cover 1 has a downwardly oriented avoidance ramp 111 around the upper edge of the lever mounting hole 11, facilitating operation of the lever 21 of the toggle switch 2 (thus forming a square conical hole at the top of the lever mounting hole 11, a common technique in the art, which will not be described further here). The upper cover 1 has a square closed-loop annular boss 12 around the lever mounting hole 11 on its back side. The toggle switch 2 is covered with a dust cap 3, which includes a lever cap 31 for covering the lever 21 of the toggle switch 2. The lever cap 31 includes a square lever cap top 310 and a lever cap body 311 surrounding the lever cap top 310 with a square closed loop. The lower end of the body 311 is provided with a square closed-loop annular sealing boss 32. The annular sealing boss 32 has an annular sealing groove 321 that mates with the annular boss 12. The back of the annular sealing boss 32 is provided with a switch cap body 33 that mates with the toggle switch 2. The inner side wall of the annular sealing groove 321 is flush with the outer side wall of the corresponding toggle cap body 311. The annular sealing boss 32 has a square closed-loop annular tip 322 near the outer side wall of the annular sealing groove 321. The annular tip 322 abuts against the back of the upper cover 1. The lever 21 of the toggle switch 2 is placed in the lever cap 31. The lever cap 31 mates with the lever mounting hole 11 on the upper cover 1 and passes through the lever mounting hole 11 on the upper cover 1. The toggle switch 2 is placed in the switch cap body 33.
[0027] In practical applications, the dust cap 3 is usually a silicone cap or a rubber cap; the wall thickness of the lever cap top 310, lever cap body 311 and switch cap body 33 is equivalent; the thickness of the annular sealing boss 32 from the bottom wall of the annular sealing groove 321 to the back of the annular sealing boss 32 is usually more than five times the wall thickness of the switch cap body 33.
[0028] In actual use, the lever 21 of the toggle switch 2 can be directly pinched by the lever cap 31 and slid in the toggle switch 2, which is very convenient to use.
[0029] In summary, the above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent variations and modifications made to the shape, structure, features and spirit described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
