Refrigerator door waterproof switch

Abstract

The invention discloses a waterproof switch of a refrigerator door. The waterproof switch comprises an upper shell, a lower shell, a static terminal, a spring, a moving terminal, a button, a cover plate, a first sealing ring, a second sealing ring and sealing oil. The lower shell is provided with a first guide groove and a second guide groove; the cover plate and the spring are respectively arranged in the lower shell; the moving terminal is installed in the first guide groove in the lower shell and abuts against the spring. The static terminal is installed in the second guide groove of the lower shell, the first sealing ring is fixed in the cover plate, the button penetrates through the first sealing ring and the cover plate from bottom to top and abuts against the moving terminal, an oiling groove is formed in the cover plate, the oiling groove is coated with the sealing oil, the second sealing ring penetrates through the button and is pressed into the oiling groove, and the upper shell is installed on the lower shell. According to the waterproof switch, the sealing oil is maintained in the oiling groove between the first sealing ring and the second sealing ring, so that the waterproof sealing effect of a button part is achieved, the long-time normal use of a travel switch is ensured, the potential safety hazard is avoided, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of refrigerator door switches, in particular to a refrigerator door waterproof switch. Background technique [0002] Existing refrigerators are all equipped with a travel switch for controlling the light source inside the refrigerator to be turned on or off, so as to facilitate the realization of the lighting function inside the refrigerator. When the refrigerator is in a long-term cooling environment, condensed water will be formed. However, the existing refrigerator travel switches are not designed to be sealed and cannot play a waterproof function. Therefore, cold air in the refrigerator easily enters the inside of the travel switch, making it The formation of condensed water will damage the limit switch, and more seriously, it will cause damage to the refrigerator and cause potential safety hazards. Contents of the invention [0003] Based on this, it is necessary to provide a refrigerator door waterp...
