[0020] As shown in the figure, the present invention discloses a waterproof rocker-shaped switch having an outer shell 2, with a swingable rocker-shaped button 1 disposed on the top of the outer shell 2. Furthermore, a card-mounting plate group is disposed around the side wall of the outer shell 2 near its top. The card-mounting plate group is composed of two adjacent and obliquely arranged card-mounting plates 5. The adjacent card-mounting plates 5 form a card-mounting groove to facilitate the fixed card-mounting of the outer shell 2. A protrusion 12 is integrally provided within the outer shell 2. A cavity 16 with an upper opening is provided within the protrusion 12. A power contact plate group and a movable contact plate 21 are disposed within the cavity 16. Specifically, the power contact plate group includes a first power contact plate 7, a second power contact plate 8, and a third power contact plate 9 disposed at intervals. The second power contact plate 8 contacts the middle portion of the movable contact plate 21. The rocker-shaped button 1 can drive the movable contact plate 21 to swing via a pressure rod 22, so that the movable contact plate 21 contacts the first power contact plate 7 or the third power contact plate 9. The boss 12 is provided with guide slots 13 and through slots 15 for each contact piece to pass through. A positioning step 14 is provided near the through slot 15. The contact piece is provided with abutment portions 25 that abut against the positioning steps 14, which can facilitate the guiding insertion and positioning of the contact piece. A support seat 20 is provided in the cavity of the boss 12. A clearance slot is provided in the middle of the support seat 20. A connecting portion 26 is provided on the second contact piece 8 to pass through the clearance slot. The connecting portion 26 contacts the middle of the movable contact piece 21. The movable contact piece 21 is swingably arranged on the support seat 20, which can facilitate the swinging setting of the movable contact piece 21. A cylindrical portion 24 is extended from the bottom of the boat-shaped button 1, and a pressure rod 22 is movably arranged in the cylindrical portion 24. A spring 23 is tightly pressed between the cylindrical portion 24 and the pressure rod 22, and one end of the pressure rod 22 is tightly pressed on the moving contact piece 21. It also includes a waterproof upper cover 3, which blocks the upper opening of the convex seat 12. A boss 10 is formed in the middle of the waterproof upper cover 3, and a makeshift hole 11 for the cylindrical portion 24 to pass through is provided in the middle of the boss 10. The outer edge of the waterproof upper cover 3 has an inserting portion 19 extending downward, and the inserting portion 19 is inserted into the gap between the outer shell 2 and the convex seat 12.

[0021] The working principle of the present utility model is as follows: by pressing the boat-shaped button 1 to cause it to swing, the pressure rod 22 will be driven to swing accordingly. The pressure rod 22 moves under the action of the spring 23 and presses the movable contact piece 21 to cause it to swing, so that the movable contact piece 21 contacts the first contact piece 7 or the third contact piece 9. Since the movable contact piece 21 itself contacts the second contact piece 8, the second contact piece 8 is connected to the first contact piece 7 or the third contact piece 9.

[0022] The structure of the present invention is to provide a convex seat in an integral manner in the outer shell, and to cooperate with the provision of a waterproof upper cover to seal the upper opening of the convex seat, and at the same time to provide an inserting portion at the outer edge of the waterproof upper cover, and to provide a sealing ring tightly pressed between the inner side wall of the inserting portion and the outer side wall of the convex seat, so as to achieve a waterproof seal between the waterproof upper cover and the convex seat. Even if liquid is poured in, the liquid cannot pass through the sealing ring and enter the interior of the convex seat, thereby ensuring that the internal energized components will not come into contact with the liquid and ensuring its stability in use. At the same time, the drainage groove provided on the outer shell corresponding to the waterproof upper cover can also achieve rapid discharge of the liquid. In addition, by designing the convex seat and the outer shell as an integrated structure, they can be directly injection molded as a whole without the need for split assembly, which makes its assembly speed faster and the production cost lower.
