Product Description
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 .
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 .
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
.
