The circle metal dome (round metal domes, circle tactile dome) is a circle(round) snap dome specifically designed for use in multi-layered circuit boards or precision switches. The C-Series domes are non-inverting and suitable for over-travel applications.
They are ideal for low-profile switches under membrane overlays and keypads and longer service life.
The size of a C-Series metal dome ranges from 2.5mm to 20mm, with trip forces typically ranging from 100gf to 600gf. Trip force, rebound/return force, click ratio, travel distance, and height can be adjusted according to client requirements.
Packaging options include bulk packaging in PE bags or pick-and-place dome arrays; when creating a dome array using automated or semi-automated machines that place the domes on glued PET film, they will be packed in steel tubes.
Regardless of your specific size and force needs, we strive to provide the best possible solution. Contact Shanyo for pricing, to order, or to request samples of C-Series circular metal domes.

- Yellow: it belongs to high-temperature resistant material (can exceed SMT high-temperature effect for a short time)
- Silver screen: grounding anti-static effect Transparency: Better alignment
- White: generally used with light guides (reflective)
- Black: generally used to block out light (obscuring the content)
