Abstract
The utility model relates to a magnetic coupling touch control button of a capacitive touch screen. A magnetic coupling touch control button portion of a waterproof pressure-resistant housing employs a static sealing or unopening way for processing, so that the hydraulic pressure is only exerted on the waterproof pressure-resistant housing. Only a button cap, an external magnetic block and one end surface of a guiding column of the magnetic coupling touch control button are contacted with the water surface; and other components of the magnetic coupling touch control button are arranged inside the waterproof pressure-resistant housing. The guiding column is in a state of gradually tightening with pressing. The button cap is supported by an internal magnetic ring and is in a suspension state and the surrounding of the button cap is in a hydraulic pressure-similar environment; and the button cap eliminates the pushing effect of the hydraulic pressure and thus the magnetic coupling touch control button is not influenced by the hydraulic pressure. A good conductor transmits charges by the guiding column, the internal magnetic ring, and a conductive rubber and thus a coupling capacitor is formed between the conductive rubber and a capacitive touch screen, thereby driving corresponding functions of digital equipment. And an out-of-control phenomenon of the touch control button by the hydraulic pressure when the digital equipment is used in water can be reduced; and water leakage of the touch control button can be effectively prevented.
