is a type of keypad, which can be touched lightly. It is a newly
developed type of electronic device. It has both the advantages
of the electronic machine products and the controlling system
of the electronic device. Membrane switch has many characteristics,
such as light and slim, dust-proof, insulation, anti-shock and
easy assembly. By virtue of those features, membrane switch
are extensively applied in medical device, industrial control,
home electronics, and precise instrument industries etc.
Graphic overlay can be textured in either matt, gloss or a
range of custom finishes in between. A matt textured finish
is very common. Windows can be printed on matt polyester to
allow clarity for LCD and LED displays and the windows can
also be tinted in a variety of colors.
Metal-dome is a tactile device which are inserted in the membrane
switch to give a physical tactile response when pressed (Clicked).
It can be designed as part of a circuit or above circuit.
A range of sizes are available. Another tactile device is
polyester dome. It is an alternative to metal dome which is
created by permanently forming one layer of the membrane into
a dome shape.
Backlighting is frequently seen in many devices. The most
effective are Electro Luminescent Backlighting (EL) and optical
fiber. We can offer EL-backlight membrane switch with perfect
Electronic equipment must be protected from unanticipated
behavior caused by RFI. We can offer membrane switch with
shielding layer if needed.
It is possible to incorporate mounted devices such as LEDs
and resistors with membrane switch. This may save allow costs
savings in PCB design while allow flexible placement of the
