EMI/RFI Shielding
A membrane switch sits directly between your electronics and the outside world — which makes it both a noise source and an entry point for interference. We integrate silver-ink, copper and carbon shielding layers with proper grounding so your product passes EMC and works reliably next to motors, radios and power electronics.
Membrane switches bridge the digital and physical worlds: long circuit traces act like antennas, and the open aperture where you press is an invitation for radiated noise. Shielding layers close that loop — and EMC labs will thank you.
Printed on PET or PI, low-cost and flexible — the default for most membrane switches.
Higher shielding effectiveness for the toughest EMC requirements.
Conductive carbon for cost-sensitive ESD and low-frequency shielding.
Dedicated tails, pins or pads that connect the shield to your PCB ground plane.
Hardened constructions that shunt static safely to ground before it reaches the electronics.
Transparent conductive films for display windows that need both shielding and optics.
