FPC Membrane Switch

Fine-pitch flexible printed circuits solderable with LEDs and precision components, rated for 1,000,000+ cycles.

FPC (Flexible Printed Circuit) membrane switches replace the conventional silver-printed tail with a copper-based flexible circuit. This enables soldering of LEDs, resistors and other miniature SMD components directly onto the circuit, with a minimum trace pitch of 0.5 mm. The circuit can be freely bent, rolled and folded to follow three-dimensional assembly paths, while maintaining a mechanical life of more than one million actuations.
