Dome Arrays, metal dome arrays & metal dome sheets (dome sheets) -- Double Layer

Metal dome contacts on the array (sheet) are positioned over the contact point of PCBs. When a dome is pressed, the center of it contacts to the PCB and let the electric current flow through. This is how metal dome arrays work.

This type is somehow similar to single layer type by means of metal dome contacts attached under Maylar. But the difference is that, in this type, the Spacer is attached under the metal dome contacts. Air paths which function like air holes in single-layer, helps provide good click-feeling when dome contacts are pressed. Besides this effect, air paths help reduce the chance for PET film being damaged by metal dome contacts' burr and block dust coming into PET films.

Character:

(1). Light & small.
(2). Damp proof, heatproof, cold proof.
(3). Dustproof is done on the Metal Dome, and oxygenation of Metal Dome has been avoided.
