Product Description
PET Membrane Switch & FPC Circuit Solutions
Membrane switches are widely used in human-machine interface (HMI) applications due to their high reliability, cost-effectiveness, and extensive customization options. While designers often focus on visible elements like overlays and backlighting, the flexible circuit behind the overlay is equally critical for performance and durability.
