Product Description
Tingfeng Hardware provides custom stamped battery contact springs for electronic lock modules, specializing in selective gold plating and compact-space elastic contact. Built on stainless steel 301 or phosphor bronze substrates, these springs deliver contact resistance ≤10mΩ with an adjustable contact force of 0.3–1.5N.
With 16 years of precision manufacturing experience, our 5–7 day rapid prototyping matches the fast iteration pace of electronic lock and access control products. Our core value lies in helping clients find the right balance between battery contact reliability and precious metal cost for consumer-grade security volumes.
Product Overview
Electronic lock modules — including smart door locks, password locks, and access control boards — have extremely compact internal spaces. Battery contact springs must provide stable contact force within limited travel while resisting micro-vibration from frequent open/close cycles.
Our springs use stainless steel 301 (balancing elasticity and corrosion resistance) or phosphor bronze (high conductivity), achieving precise spring arm geometry through precision stamping. Selective gold plating applied only to battery contact areas ensures ≤10mΩ contact resistance while controlling precious metal usage, avoiding the cost waste of full-surface gold plating.
For different battery compartment layouts and PCB mating methods, we provide non-standard customized spring shape and contact force design, ensuring reliable contact in compact spaces. Each batch undergoes contact resistance and force testing, making these springs suitable for smart door lock battery compartments, access control board power contacts, and electronic lock backup battery connections.
