Structure
■ Circular Contact
PET film (white)
(with matrix adhesive)
Stainless steel
contact dome
When contact dome keys 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 keys that provide
contact at the center point only.
Polyurethane
rubber film (with adhesive)
(circular contact)
The circular contact construction provides contact along the circumference of
a circle, thus preventing poor contact by avoiding the center point.
Contact dome resistant to
Conventional models
forei g n matter (circular contact)
■ 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.
