The graphics are made on the film substrate, and the entire component is a switch function, so it is called a membrane switch. The low profile tactile switch is made of several layers of films of different materials and is bonded into a finished product. Due to the short action stroke of this low profile tactile switch, it is only about 0.25~0.5MM, and the switch pressing force is 0.5~1N, which is more sensitive, and the switch is completed by light touch effect.
The panel layer is generally made of exquisite patterns and texts on the colorless light-transmitting sheet of less than 0.25MM, such as PET and PC. Because the main function of the panel layer of the low profile tactile switch is to play the role of identification and keys, so choose The material must have the characteristics of high transparency, high ink adhesion, high elasticity and high toughness.
The main function of the surface glue 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 between 0.05-0.15MM, with high-strength viscosity and anti-aging properties; in production In general, special membrane switch double-sided adhesive is used. Some membrane switches require waterproof and high temperature resistance. Therefore, the surface adhesive must also use materials of different properties according to needs.
The use of adhesive is closely related to what material the low profile tactile switch is attached to. Common double-sided adhesives, 3M adhesives, waterproof adhesives, etc. are commonly used.
