Medical Healthcare Metal Dome Pet Keypad Membrane Switch with Cable Connectors
A 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.
> Construction:
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 backlighting membrane switches, LGF backlighting membrane switches, EL backlighting 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 switch etc.
> Application
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.
