Dome Arrays, metal dome arrays & metal dome sheets (dome sheets) -- Single Layer
The Metal dome array (dome array) is the most cost effective solution for a simple switch with a superior tactile interface between your equipment and the user. A metal dome array & sheet (dome array) is a kind of PET sheet that carries metal dome contacts. It is applied to PCBs to function as switches of mobile phones and electric home appliances. Compared to the membrane polyester switch which was formerly used, it gives good click-feeling. It also gives much longer lasting life span compared to poly dome sheets. It also takes place of down going productivity of tact switches with its potential productivity.
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.
It is possible to manufacture metal dome arrays with various size and weight to meet customers' request. And of course it's possible to be developed into various types followed by customers' requests. At present, we make the following basic types of dome arrays.
This type is used in the early period of metal dome arrays (dome arrays) industry. Metal dome contacts are attached under Maylar (one layer of adhesive PET film). On the sheet, there is an air hole for each dome contact and it is essential for good click-feeling.
(1).light & small
(2).Nice handle & returned dome with breathe freely hole on METAL DOME.
(3). Mainly used in cheap single layer PCB.
