LED Membrane Switch for LCD Screen
LED membrane switch is to assemble one or several LED chips on the switch traces as the backlighting element, to achieve the lighting of the interface. The switch operates by creating a connection when pressure is applied to the membrane layer, causing a circuit to close and register a keystroke or command. Membrane switches are commonly used in various electronic devices which need uniform lighting, such as control panels, keypads, remote controls, and other interfaces where a compact, durable, and cost-effective solution is needed.
