Product Description
PET Membrane Switch with Tactile Dome Button
Membrane switches, also called membrane keypads, are constructed from thin polycarbonate or polyester film with pressure-sensitive adhesive. These switches are manufactured by screen printing circuits directly onto plastic substrates using silver or carbon conductive ink. Their simple, versatile, durable, and economical design makes them a superior alternative to mechanical switches.
