The switch film 13 includes a first film layer 131, a first electrode 141, a second film layer 132, a second electrode 142, and a colloid 133. The switching film 13 can be turned on or off by the first electrode 141 and the second electrode 142 being turned on or off. Further, the colloid 133 is water-repellent and is bonded between the first film layer 131 and the second film layer 132 to prevent moisture or moisture from entering to make the switch film 13 waterproof.

The conventional colloid 133 is generally formed on a film layer by printing, and another glue layer is overlaid on the colloid 133 so that the colloid 133 is bonded between the two film layers. However, in the process of colloid printing, when there is a lack of glue or foreign matter, it is easy to cause waterproof failure of the switch film 13. For example, when the gel is generated, the colloid 133 does not have a sufficiently thick rubber wall to block moisture or moisture, or the bonding property is insufficient to block moisture or moisture infiltration, and the waterproofness of the switch film 13 is lowered. Therefore, how to strengthen the bondability and barrier property between the colloid and the two film layers, and reduce the chance of moisture or moisture infiltrating into the switch film is a problem that the industry is eager to solve.

This creation is about a waterproof keyboard structure with an improved waterproof structure to reduce the chance of moisture or moisture seeping into the switch film.
