Product Description
Micro Miniature Compression Spring 2mm OD for PCB Switches Custom Rate
We specialize in manufacturing ultra-precise miniature compression springs with outer diameters from 1.2-4mm and wire diameters from 0.08-0.3mm. Our custom spring solutions are ideal for PCB switches, tactile feedback mechanisms, battery contacts, and micro valves in compact electronic devices.
Compression Spring Overview
For compact devices like smartphones, TWS earbuds, and smartwatches, dimensional tolerance and force consistency of micro springs directly determine button feel and electrical contact reliability. Our Japanese high-precision computer-controlled spring formers with fine wire tension control achieve ±0.01mm OD repeatability for exceptional consistency.
We employ 100% CCD vision inspection specifically for micro springs, automatically measuring OD, free length, and coil count while rejecting any tangled or deformed springs. For automated placement, we offer tape-and-reel packaging directly compatible with SMT lines. Our engineering team provides design optimization to achieve target force within limited space constraints.
Features & Advantages
| Feature | Advantage to You |
|---|---|
| Ultra-fine wire capability (0.08mm) | Manufacture springs as small as 1.2mm OD for the tightest spaces |
| 100% CCD Optical Sorting | Ensures every spring is dimensionally correct and tangle-free, preventing assembly line jams |
| Tape & Reel Packaging (SMT Compatible) | Directly feed into pick-and-place machines, boosting production efficiency |
| Custom Spring Rate | Precisely calculate wire diameter and coil count per your button force or contact pressure requirement |
| 48hr Rapid Sampling | Micro springs also benefit from fast sampling to accelerate prototype validation |
Technical Specifications
| Specification Item | Detail / Capability | Notes / Description |
|---|---|---|
| Min Wire Diameter | 0.08mm (±0.003mm) | Music wire or SUS304 |
| Min Outer Diameter | 1.2mm (±0.02mm) | 1.5mm+ recommended for stable production |
| Min Free Length | 1.5mm (±0.1mm) | Very short springs require evaluation |
| Spring Rate | 0.01 - 5 N/mm | Calculated per load |
| Recommended Coils | 3 - 15 | Fewer coils may cause unstable rate |
| End Type | Closed not ground (std) / Closed & ground (opt) | Micro springs generally not ground |
| Packaging | Tape & reel / Anti-static tube / Bulk | Reel orientation customizable |
| Sample Lead Time | 48-72 hours | Depending on complexity |
Applications
- Smartphones & Wearables: Tactile feedback springs for side keys and power buttons; battery contact springs for earbud charging cases
- Micro Switches & Relays: Return springs for tactile switches, toggle switches, and micro signal relays
