Membrane switches are touch-control switches with a multi-layered structure, and are employed in the user interfaces of electronic products. They were originally used mostly in military applications, but were gradually been adopted by private
firms for use in office equipment and everyday appliances. Membrane switches are chiefly used to replace the conventional switches used in keyboard keypads. The use of membrane switches instead of clumsy parts and complicated circuitry can
save plenty of space and yield a more attractive product, while also dramatically cutting costs. Depending on product needs, membrane switches can made waterproof, heat-resistant, abrasion-resistant, or scratch-resistant...etc.

The following table provides a general classification of membrane switches and displays their structures:
