| DR-series is designed to seek spacial advantage by symmetrically D-cutting circle dome and thus preferred
for high-density design such as navigation keys. In addition, DR-series that structurally can keep the strokes
higher enables more distinctive tactile feel. Made of optionally Ni, Ag or Au-plated SUS301, three different
domes with each size and trip force are available; however, Φ 5-sized dome with trip force 170g is highly
preferred for its stable functions and tactile feel.
More different trip forces but 170g and 190g can be provided to your specific requirements. |
