Furthermore, since the third protrusion 24 of the second button unit 2 of the waterproof button module 200 and the first button unit 1 have a key spacing I between the opposite sides of the first pressing surface 11, the first button The unit 1 is pressed down by the water pressure and the first button unit 1 When the pressing distance is smaller than the key spacing I, the first button unit 1 does not drive the second button unit 2 to be depressed. Therefore, the electronic device 300 can be used under the water surface, and the malfunction of the button is less caused by the water pressure.

In summary, the waterproof button module of the present invention adopts a daughter-type button. Since the surface area of the second pressing surface of the waterproof button module can be designed to be less affected by the water pressure according to the user's requirements, the button does not malfunction due to the water pressure. In addition, when the user presses the second pressing surface of the waterproof button module, because the second protruding portion is adjacent to the third protruding portion and slightly abuts against the third protruding portion, the second button unit is less likely to be left or right. shake. Furthermore, since the third protrusion of the second button unit of the waterproof button module and the first button unit have a key spacing between the opposite sides of the first pressing surface, when the first button unit is pressed by water pressure When the pressing distance of the first button unit is less than the button spacing, the first button unit does not drive the second button unit to press down to the top of the switch unit, thereby causing malfunction of the waterproof button module and its electronic device.
