Speed Up Dome Switch Production Without Sacrificing Quality
Custom dome arrays provide a reliable, low-profile switching solution for products that require consistent tactile feedback. By integrating multiple metal domes into a single adhesive-backed sheet, arrays simplify assembly, reduce alignment errors, and improve long-term durability. Engineers choose dome arrays to streamline production, minimize cost, and ensure uniform switch performance across every device.
Why Choose a Custom Dome Switch Array?
- Precise alignment with your circuit board or flexible substrate
- Optimized tactile response through custom dome force, size, and shape
- Design options for LED windows, embossing, and EMI shielding
- Adhesive systems selected for temperature, chemical, and application demands
What We Customize
We can tailor nearly every aspect of your dome array from size and force to material, cutouts, and more.
| Feature | Description |
|---|---|
