The waterproof structure of the soft rubber button includes a box body 10, a soft rubber board 20 and a control board 30 with a plurality of buttons 32. The soft rubber board 20 has a plurality of pressing parts 221 arranged at intervals and used for the operator to press the button 32. The soft rubber board 20 is first injection-molded with a plastic mold to form a plastic bracket 21 for support. The plastic bracket 21 is then placed in a silicone mold for secondary injection-molding of a silicone layer 22 on the outside of the button 32. The part of the silicone layer 22 corresponding to the outside of the button 32 is the pressing part 221. The advantage of this is that the appearance and waterproof parts are all silicone, and there is plastic support in the middle, which can make the entire button 32 have better structural strength without affecting the appearance and waterproof requirements. Of course, the above-mentioned soft rubber is not necessarily silicone, and can also be other glue with waterproof properties.
