R-series metal domes

R- series metal domes is round- shaped as the very basic type of metal domes

R- series metal domes is round- shaped as the very basic type of metal domes developed to overcome then existing poly domes bounds in such features as tactile feel, durability and quality consistency. Made of SSTL, optionally Ni, Ag or Au- plated SUS- 301 is prepared for each size of ? 3. 2, ? 3. 5, ? 4, ? 4. 5 , ? 5, 6 or ? 8. 4 and standardized in trip forces to the feature of each dome; however, more various trip forces can be provided to your specific requirements. As the R- series dome has been improving to different types, its usage has been decreasing and yet it has such advantages as stable productivity and quality, stable contact and least contact point damages.
