Custom 304 Stainless Steel Touch Spring with Passivation, 0.6mm Wire Diameter, 22×22×16mm

This custom touch spring is precision manufactured from 0.6mm 304 stainless steel wire, designed for use as a contact or conductive spring in electronic assemblies. The spring is formed to dimensions of 22×22×16mm, with specially bent terminal hooks for secure mounting and electrical connection. After forming, it undergoes passivation treatment to enhance corrosion resistance, improve surface stability, and ensure long-term reliability in various environments. The consistent spring force and dimensional accuracy make it ideal for applications requiring reliable electrical contact and mechanical support.
