Fig. 1 to 10 show a preferred embodiment of a switch structure of a refrigerator lamp according to the present invention. As shown in the figures, the refrigerator lamp switch structure comprises a sealing box 3 and a lamp switch 1, wherein the sealing box 3 has a containing space which is matched with the lamp switch 1 and is used for containing the lamp switch 1, and the size of the containing space is slightly larger than the external size of the lamp switch 1. The top of the sealing box 3 is opened to form an opening from which the lamp switch 1 can be inserted into the accommodation space. One side of the lamp switch 1 is provided with an elastic sheet 1-1 which is used for abutting against the inner wall of the sealing box 3, and the inner wall of the sealing box 3 is provided with a clamping part 3-1 which is matched with the elastic sheet 1-1. The clamping part 3-1 comprises an inclined plane structure 3-1A positioned at the top of the inner wall of the sealing box and a clamping groove 3-1B arranged at the bottom end of the inclined plane structure. According to the refrigerator lamp switch structure provided by the invention, the lamp switch 1 is provided with the elastic sheet 1-1 matched with the clamping part 3-1 on the inner wall of the sealing box 3, so that the sealing box 3 and the lamp switch 1 are tightly and firmly connected, and the lamp switch 1 is tightly and firmly matched in the sealing box 3, so that the PL tension requirement is met under the condition of no reinforcing plate. In addition, this refrigerator lamp switch simple structure owing to cancelled the reinforcing plate, therefore need not paste the reinforcing plate by full-time personnel to improve production efficiency, the cost is reduced, and this refrigerator lamp switch structure reliability is high, and quality stability is strong.

In order to facilitate the positioning of the lamp switch 1 in the sealing box 3, a first limiting portion 3-2 and a second limiting portion 3-3 are respectively arranged on two side walls of the sealing box 3, and the two side walls are adjacent to the side wall provided with the clamping portion 3-1. Preferably, the first limiting part 3-2 and the second limiting part 3-3 are of rib structures integrally formed with the seal box 3. For example, the sealing box 3, the first limiting part 3-2 and the second limiting part 3-3 are all plastic parts and can be formed into an integral structure by injection molding.
