WATERPROOF STRUCTURES
There are two waterproof structures. The waterproof structure is generally designed as a back-shaped embedded structure. One structure is made of the same material and divided into two parts to make a finished product, and the circuit part is embedded in the panel part to form a product. This structure is more commonly used, and waterproof glue is used for each layer of glue; the other structure is to use materials with a thickness of upper and lower circuits and isolation layers and make the outer frame structure of the Membrane Switch with the panel, and the circuit part is embedded inside. into a whole.
