PET Film for Membrane Switch

PET film for membrane switch use forms the layered structure behind many everyday control panels. It serves as the graphic overlay, circuit layer and spacer, giving each key a light, responsive touch that springs back reliably after every press. The film resists repeated flexing, moisture and common cleaning agents, so panels stay readable and functional over a long service life. Its smooth surface takes sharp printing for icons, text and display windows, and it holds its size during screen printing and lamination so circuits line up accurately. It is widely used in household appliances, medical devices, industrial controls, instruments and remote controls. Custom thicknesses, surface finishes and samples are available for your switch designs.
