[0017] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Specific Implementation Example 1: Combined with Appendix Figure 1 and attached Figure 2 As shown, a novel waterproof switch includes a housing 10 and a base 20. The base 20 is installed at the lower cavity of the housing 10. A pressure handle 30 is provided on the upper side of the housing 10. The pressure handle 30 is used to drive the contact piece of the housing 10 to slide down and connect with the end foot at the base 20. A rubber cap 40 is fitted on the pressure handle 30. The rubber cap 40 shrinks and seals between the pressure handle 30 and the housing 10, thereby sealing and waterproofing the upper side of the housing 10.

[0019] The base 20 has protruding latching parts 21 on both the front and rear sides. The inner wall of the housing 10 has latching grooves 11 that mate with the protruding latching parts 21. Sealant is applied between the base 20 and the housing 10 to seal and waterproof the lower side of the housing 10. The housing 10 has a latching pressure relief hole 13 at the latching groove 11. When the base 20 and the housing 10 are fastened together, the protruding latching parts 21 of the base 20 are engaged with the latching grooves 11 of the housing 10, and the air in the latching grooves 11 can be discharged through the latching pressure relief hole 13.

[0020] Specifically, the boss-shaped latching part 21 is an arc-shaped boss, and the latching groove 11 is an arc-shaped groove corresponding to the boss-shaped latching part 21. The arc-shaped boss-shaped latching part 21 facilitates insertion into the latching groove 11 of the housing 10, enabling quick installation. (See attached...) Figure 1 As shown, the inner cavity of the housing 10 is provided with a limiting rod 12 for limiting the installation depth of the base 20, and the limiting rod 12 is located on the upper side of the snap-fit ​​groove 11. When the base 20 is installed under the housing 10, the limiting rod 12 presses against the base 20, thereby limiting the base 20.

[0021] As attached Figure 1 As shown, the base 20 has a first end foot 201 and a second end foot 202, which are arranged vertically parallel to each other. Additionally, as shown in the attached... Figure 4 As shown, the first end foot 201 and the second end foot 202 at the base 20 can also be straight rods. (See attached image) Figure 5 As shown, the first end foot 201 and the second end foot 202 at the base 20 can also be in the shape of a bent rod.

[0022] Specific Implementation Example 2: Combined with Appendix Figure 1 and attached Figure 3 As shown, a novel waterproof switch includes a housing 10 and a base 20. The base 20 is installed at the lower cavity of the housing 10. A pressure handle 30 is provided on the upper side of the housing 10. The pressure handle 30 is used to drive the contact piece of the housing 10 to slide down and connect with the end foot at the base 20. A rubber cap 40 is fitted on the pressure handle 30. The rubber cap 40 shrinks and seals between the pressure handle 30 and the housing 10, thereby sealing and waterproofing the upper side of the housing 10.

[0023] The base 20 has protruding latching parts 21 on both the front and rear sides. The inner wall of the housing 10 has latching grooves 11 that mate with the protruding latching parts 21. Sealant is applied between the base 20 and the housing 10 to seal and waterproof the lower side of the housing 10. The housing 10 has a latching pressure relief hole 13 at the latching groove 11. When the base 20 and the housing 10 are fastened together, the protruding latching parts 21 of the base 20 are engaged with the latching grooves 11 of the housing 10, and the air in the latching grooves 11 can be discharged through the latching pressure relief hole 13.

[0024] As attached Figure 3 As shown, it also includes a lower housing 50, which has a lip 51. When the lower housing 50 is connected to the base 20, the lip 51 of the lower housing 50 engages with the lower cavity of the housing 10. The lip 51 of the lower housing 50 has an outward protrusion 52, and the lower cavity of the housing 10 has a groove 14 that mates with the outward protrusion 52. The lower housing 50 also has a plug insertion hole 53.

[0025] As attached Figure 1As shown, the base 20 has a first end foot 201 and a second end foot 202, which are arranged vertically parallel to each other. Additionally, as shown in the attached... Figure 4 As shown, the first end foot 201 and the second end foot 202 at the base 20 can also be straight rods. (See attached image) Figure 5 As shown, the first end foot 201 and the second end foot 202 at the base 20 can also be in the shape of a bent rod.
