    The most important role of the adhesive is to closely connect the panel layer and the circuit layer to achieve the effect of sealing and connection. This layer generally requires a thickness of 0.05 --- 0.15MM, with high strength and anti-aging properties; in production In general, special membrane switch double-sided adhesive is generally used. Some membrane switches require waterproof and high temperature resistance. Therefore, the surface adhesive must also use different materials according to needs.
