Raised Structure

Semi-coaxial pad & plain metal dome

Advantage: Single-sided circuit patterning, high click ratio

Bridge Structure

Bossed dome & short bar contact bridge
FPC (ø6.0mm dome only)

Advantage: Single-sided circuit patterning,
high click ratio
Disadvantage: only for ø6.0mm dome

Using the short bar contact, shown above,
on a rigid PCB with metal dome may cause
a defect in the electrical contact of on-
timing, due to a combination of
microscopic unevenness of plating
thickness on the conductor and dome
