Silicone Rubber Keypad PET metal dome membrane circuit
Rubber keypad switch structure and switch assemblies
As
we
all
know,
the
general
membrane
keypad
has
five
layers.
Graphic
overlay,
the
adhesive
layer,
metal
dome,
circuit
layer,
and
back
adhesive.
Assemble
these
layers
together,
membrane
switches
with
tactile
response
are
made.
Benefit
from
the
use
of
metal
dome,
you
have
the
tactile
feel
when
pressing
the
key
top
to
function.
And
the
service
life
of
membrane
keypads
also
depends
on
it.
For
the
silicone
keypad
switch,
the
graphic
overlay
layer
uses
rubber
material.
And
it
always
uses
a
printed
circuit
board
as
a
circuit
layer.
Using compression molding properties of custom silicone rubber material, the supplier creates gradient webbing around the button center. After pressing down the button, the web deforms to produce a tactile response. Remove the actuation force from the switch the webbing returns to its neutral position with positive feedback. For consumer and industrial electronic products, the carbon pill or metal dome is adopted to contact the printed circuit board when the web has been deformed to conduct electricity. Huaisong Industrial, which designs and manufactures cost effective silicone keypads since 2010, can also make membrane switch assembly.
