LED Tactile Switch for Telecommunication Machine

The LED membrane switch incorporates a layer of light guide film as the backlighting element to illuminate the interface. Activation occurs when pressure is applied to the membrane layer, closing the circuit and registering a keystroke or command. Widely employed in electronic devices requiring uniform lighting, such as control panels, keypads, and remote controls, membrane switches provide a compact, durable, and cost-effective solution.
