Membrane switch is an electrical switch for turning a circuit on
and off. It differs from a mechanical switch. Membrane switch is
very thin and soft. The touch surface material usually is PET or
PC. The circuit can be PET, FPC or even PCB. Membrane switches are
user-equipment interface utilities that allow for the communication
of commands from users to electronic devices.
A membrane switch typically has 6 or more or less layers. The top
layer of a membrane switch is the graphic overlay interface between
the user and the machine. The other critical layer is a the circuit
layer. It can also be PET, FPC or PCB. All the layers are normally
assembled using pressure-sensitive adhesives. Contact between two
traces can be made through a printed shorting pad or through a
metal dome that stands on legs.
> What kind of membrane switches we can produce?
Super big size membrane switches, membrane keypads, graphic
overlays, membrane circuits, LED back lighting membrane switches,
LGF back lighting membrane switches, EL back lighting membrane
switches, capacitive membrane switches, rubber keypad membrane
switches, FPC circuit membrane switches, PCB circuit membrane
switches, metal back panel membrane switches, Acrylic/PC back panel
membrane switches,, waterproof membrane switch, anti-UV membrane
switch, anti-scratch membrane switch, digital printing membrane
Classic applications of membrane switches include consumer
electronics like the microwave oven panel, air conditioner control
panel, TV remote control etc., machinery, test instrument, meters,
medical industry, energy industry, Auto industry, aviation
industry, healthcare industry etc. Tactile feedback of keys can be
provided by embossing the top PET/PC layer or embedding metal snap
domes, polyester domes or forming the graphic layer.
The benefits of membrane switches include flexible, easy of
cleaning, sealing ability and low profile.
