Hard‑Gold Rotary Code Switches That Go the Distance
PTR HARTMANN rotary code switches use abrasion‑resistant hard gold plating—delivering stable, long‑term performance far beyond common flash‑gold alternatives.
Why They Last Longer:
• Up to 1.2 μm hard gold for reliable conductivity even after 30,000+ switching cycles
• Full electronic inspection for consistent, repeatable quality
• Easy, secure assembly with pure tin‑plated solder pins and multiple connection options (3+3 / 4+1)
These switches deliver the consistency your applications demand.
