About Us
MembraneSwitchFactory is a Shenzhen-based manufacturer of custom membrane switches, graphic overlays, silicone keypads, capacitive touch panels and complete HMI assemblies. We exist for one reason: to make sourcing custom interfaces simple, fast and honest for product teams that don't have a factory on speed dial.
Most interface projects fail because of communication, not technology. We built this company to prove that a factory can be as responsive as an in-house team.
We started as a small team of process engineers working in membrane switch production. Day after day we watched good products lose time to the same problems: unclear drawings, mismatched materials, slow samples and scattered suppliers.
So we built the operation we wished existed. Today our factory runs precision printing, die-cutting, lamination, silicone molding, touch-sensor fabrication and assembly under one roof, and a single export office in Shenzhen manages every project from first email to delivered container.
Eight in-house disciplines cover nearly every custom interface project — which means your tolerances stack correctly and your schedule doesn't depend on five different suppliers.
Stack-up design, tolerance analysis and material selection reviewed before any tooling is cut.
Steel-rule and laser cutting with ±0.1–0.15 mm tolerances for overlays, spacers and gaskets.
Pantone-matched inks, fine-line printing and UV-cured hard coats for durable graphics.
Silver-ink and copper circuit printing with precision lamination in dust-controlled areas.
LSR injection and compression molding with in-house tooling for custom rubber keypads.
Projected capacitive sensors on glass and film, tuned and tested to your controller.
SMT and through-hole assembly with programming, test fixtures and burn-in.
Actuation force testing, electrical checks, visual inspection and environmental testing.
Four inspection gates catch problems while they're still cheap to fix — before lamination, before assembly, before packing and before shipping.
