The metal dome arrays is a switch contact system . It is composed
of a PET sheet containing a metal dome and plays an important
tactile switch between the user and the instrument .Â
The snap dome on the conductive film is located on the conductive
part of the PCB (above the gold finger) . When pressed , the center
point of the pot piece is concave and contacts the line of the PCB
, thereby forming a loop and passing current to realize the
switching function .Â
The meta dome arrays can be attached to various circuit substrates
, such as a hard PCB board , an FPC soft board , a PET flexible
circuit , or the like . Metal shrapnel conductive films are
commonly used in telecommunications equipment , industrial
equipment , automotive systems , and household appliances .
Compared to conventional mechanical switches , it is lighter in
weight , thinner in size , and smaller in size , enabling smaller
and thinner packages; durable , mechanically and electrically
stable for rugged and high-performance applications . Can be used
in combination with film panels , silicone s and light guides
.Â
