What are Silver Flex Membrane Switches (membrane keypad/keyboard switch/thin film switch)?
Silver Flex membrane switches are the most common construction for flexible, custom membrane keypads. It is also the most popular membrane switch construction due to its affordability, especially when compared to bulky, costly electromechanical switch assemblies. Silver flex membranes switches feature very thin flexible layers of material, of which some layers utilize screen printed silver and carbon conductive inks, and are separated by an adhesive layer.
What are the Silver Flex Membrane Switch Design Options?
Our flat key membrane switches are renowned for providing absolute reliability even in the most hostile of operating environments. With a vast array of technical specifications available the perfect solution can always be offered by FLEXKYS.
