Construction
Circular Contact
When Dome Arrays are attached to the PCB, any PCB dust or
foreign particles will tend to collect in the center of the key when it is

pressed. Therefore, poor contact occurs easily in Dome Arrays that
provide contact at the center point only.
The circular contact construction provides contact along the circumference
of a circle, thus preventing poor contact by avoiding the center point.

Matrix Adhesive
The surface structure of this adhesive has grid-shaped slits, as
shown in the following cross-sectional diagram. These slits provide
both ventilation and dust-proofing, which is required for contact dome
operation.
