- 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.
- Metal dome array is a kind of PET sheet that carries contacts. It
is applied to to function as switches of mobile phones and electric
home appliances. The dome array (metal dome array)is the most cost
effective solution for a simple switch with a superior tactile
interface between your equipment and the user. 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.
- Contacts on the arrays (sheets) 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.
- We can supply different sizes and variations of metal domes, and
has extensive experience in metal dome array applications to assist
in optimizing designs for every requirement.-
