Intertek Assessed Verified On-site Production Capacity & Quality Management Systems Original contract reviews from certified overseas engineering and procurement teams.
"The tactile feel of the metal dome keys is crisp and exact to our mechanical tolerance specs. The transparent LCD window adhesive showed no bubbling, and every unit in our 2,500 pcs run passed electrical continuity inspection on arrival. Zhejiang ZIRA Membrane Switch Co., Ltd. has proven to be an exceptionally competent engineering partner."
"Outstanding communication during the DFM phase. They noticed a pin-out clearance issue on our flexible tail schematic and corrected it before fabrication, saving us weeks of delay. Delivery via DAP Munich was strictly on time, and 3M adhesive bonding holds up against industrial chemical exposure."
"The compression-molded silicone elastomer keys with laser-etched translucent legends look exceptional when backlit by our RGB board. Conductive carbon pills have consistent contact resistance (<50 ohms). Moisture and saltwater perimeter gaskets have passed IP67 submersion testing flawlessly."
"Color matching against our corporate Pantone guidelines was spot-on. Textured matte PET substrate resists scratches and aggressive disinfectant wipes in biological clean rooms. Fast prototyping service—first article inspection units were in our Birmingham labs within 7 days."
Every switch leaving our Ningbo facility is backed by 29 years of manufacturing expertise, verified third-party facility audits, and uncompromising testing protocols.
Open circuit, short circuit, loop resistance, and insulation tests are executed across every single tail connector prior to shipping.
Engineered using authentic Autotex PET, Lexan PC, 3M 467MP/468MP adhesives, and high-conductivity silver pastes.
Nickel-plated or gold-plated stainless steel metal domes rigorously cycle-tested to ensure tactile crispness and durable contact life.
