Membrane switches, as an advanced electronic switching product, have seen widespread application across numerous sectors in recent years. With their compact size, light weight, simple structure and stable performance, they have progressively replaced traditional mechanical switches. Within membrane switch products, the application of LEDs has also become increasingly prevalent, establishing them as a highly promising tool for illumination and indication.
Ultra-thin and lightweight: Achieves exceptionally slim overall thickness (typically <1mm), making it ideal for modern, space-constrained devices requiring minimal profile.
Stylish appearance: Features a smooth, flat surface that is easy to clean, enabling intricate patterns, colours, and lighting effects to be incorporated, delivering both technological sophistication and aesthetic appeal.
Superior sealing: Capable of achieving complete sealing, offering protection against water, dust, oil, and chemical corrosion.
Pleasant Tactile Feedback: Utilising different spring sheets (e.g., metal or polyester) delivers either a distinct “click” sensation or a soft linear response.
High Integration: Multiple keys, LED indicators, and even resistors/capacitors can be integrated onto a single membrane, simplifying overall product design.
Exceptional Durability: Long service life, typically withstanding over a million presses.
Indicators: LEDs serve as indicators in membrane switch products, such as power switches and function keys. As their brightness and colour can be adjusted according to practical requirements, they clearly display switch status and the operational state of electronic devices.
Backlighting: Within membrane switch products, LEDs may also function as backlighting to enhance switch visibility and usability. Adjusting LED brightness and colour enables more comfortable reading and operational experiences.
Functional Illumination: LEDs can provide functional illumination in membrane switch products, such as keyboard lighting or control panel illumination. This application improves operational accuracy and comfort, proving particularly suitable for low-light or dark environments.
Automotive Industry: Utilised in vehicle interior buttons such as door handle switches and boot release keys, providing clearly visible operational guidance at night while offering waterproof and oil-resistant properties to meet external automotive environment requirements.
Smart Home: Commonly found in control panels for appliances like air conditioners, washing machines, and microwaves, as well as operating interfaces for smart curtains and door locks, enabling intelligent control and convenient human-machine interaction.
Industrial Control: Suitable for operation panels and instrument clusters in automated equipment. Its waterproof, dustproof, and corrosion-resistant properties adapt to industrial settings, delivering stable and reliable operational guidance.
Medical Devices: Highly favoured in frequently interacted-with medical equipment like portable monitors and ventilators due to its ease of cleaning and waterproof/dustproof characteristics. This aids in maintaining hygiene and safety standards for medical apparatus.
