Membrane switches, also known as membrane keyboards or graphic overlays, are sophisticated electrical switches used to turn circuits on and off. Unlike traditional mechanical switches made of copper and plastic, membrane switches utilize circuits printed on high-quality PET or ITO substrates.

The conductive elements are created using specialized screen-printing inks filled with silver, copper, or graphite, ensuring high performance and reliability. These interfaces serve as critical communication links between users and electronic devices across various industries.
