This type of membrane switch can be installed with LEDs inside. When the corresponding button is pressed, the LED will light up and be used only as the operating area of the switch. JRPanel uses Everlight's Everlight package as a 1206 SMD LED. The LED light is welded on the circuit under the membrane switch to assemble it as a whole. The LED light window is often bumped. This type of product is mainly used for the function keyboard of the industrial control equipment of the man-machine interface.

Membrane switch is an electrical switch for turning a circuit on and off
Differs from a mechanical switch
Membrane switch is very thin and soft
Touch surface material usually is PET or PC
Circuit can be PET and FPC or even PCB
Membrane switches are user-equipment interface utilities that allow for the communication of commands from users to electronic devices

> Construction:
Membrane switch typically has 6 or more or less layers
Top layer of a membrane switch is the graphic overlay interface between the user and the machine
Other critical layer is a circuit layer
Can also be PET and 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 and digital printing membrane switch
 
> Applications:
Classic applications of membrane switches include consumer electronics like the microwave oven panel, air conditioner control panel, TV remote control and more, machinery, test instrument, meters, medical industry, energy industry, auto industry, aviation industry and healthcare industry
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
