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
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 combination technique.
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 PCB.
