PET Touch Key Circuit

Product Description

Our PET Printed Touch Key Circuits are produced on durable PET substrates with precisely printed conductive ink layers, forming stable touch key contacts for membrane switch assemblies.
The circuit layout can be customized to support different key structures, contact patterns, and electrical requirements.

Designed for high-cycle operation, these circuits offer excellent flexibility, dimensional stability, and resistance to wear.
They can be easily integrated with graphic overlays, spacer layers, metal domes, LED indicators, and connectors to create complete membrane switch solutions.

We provide full in-house services, including circuit design, prototyping, and mass production, ensuring consistent quality and fast turnaround for OEM and ODM projects.
