Membrane
switch
is
an
operating
system
that
integrates
button
functions,
indicating
elements,
and
instrument
panels.
It
consists
of
four
parts:
panel,
upper
circuit,
isolation
layer
and
lower
circuit.
When
the
membrane
switch
is
pressed,
the
contacts
of
the
upper
circuit
are
deformed
downwards
and
are
in
contact
with
the
plates
of
the
lower
circuit.
After
the
finger
is
released,
the
contacts
of
the
upper
circuit
bounce
back,
the
circuit
is
disconnected,
and
the
circuit
triggers
a
signal.
Membrane
switch
has
rigorous
structure,
beautiful
appearance
and
good
sealing
performance.
It
has
the
characteristics
of
moisture
resistance
and
long
service
life.
Widely
used
in
electronic
communication,
electronic
measuring
instruments,
industrial
control,
medical
equipment,
automobile
industry,
smart
toys,
household
appliances
and
other
fields.

PET Membrane Switch Overlay Applications:
1. The mobile phone
Focuses on the flexible circuit board light weight and thin thickness. Can effectively save the volume of products, easy connection of the battery, microphone, and buttons and into one.
2. Computer and LCD screen
Use the one line configuration of flexible circuit boards, and thin thickness. The digital signal into the picture, through the LCD screen
3. CD player
Focuses on three dimensional assembly characteristics of flexible circuit boards and thin thickness. The huge CD to carry around
4. Disk drives
Regardless of the hard disk, or diskette, is very dependent on FPC high softness and thickness of the 0.1 mm slim, read data finish quickly. Either a PC or NOTEBOOK.
5. The latest applications
Hard disk drives (HDDS, hard disk drive) of suspended circuit (Su ensi. N cireuit) and the components of xe packaging board, etc
