title icon1Double layer dome arraytitle icon2

This type of聽dome array聽(metal dome sheet) is somehow similar to聽single layer type聽by means of metal dome contacts attached under Maylar. But the difference is that, in this type, the Spacer is attached under the聽metal dome聽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聽metal dome聽contacts' burr and block dust coming into PET films.

We not only put several dome on a array, but also put just one piece per array, so that customer can just peel off each piece and put it on key location of Keyboard/聽FPC/聽PCB. You can easily peel off the single metal dome array from release liner backing and adhere it firmly on your PCB, FPC or membrane switches, and we named it "聽Standard Single Key Dome Array".

This is one of our standard metal dome array, which consists of single metal domes on a pressure sensitive adhesive PET sheet (array), and each single metal dome is in the center of kiss-cut adhesive square or circle, with release backing which is easily peeled off. So sometimes, people also named “Kiss-cut peel off one dome array”, or “peel-off kiss-cut single key dome array”. Or say its full name as “Standard Single Key Metal Dome Array” For more information, please see "聽Standard Single Key Dome Array聽"

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
