Capacitive Touch Sensor Switch With Back Light LED
The Capacitive Touch Sensor Switch with Backlight LED is an advanced user interface component designed for seamless integration into modern electronic systems, offering touch-sensitive operation without physical moving parts for enhanced durability and aesthetics. Available in four vibrant backlight options—red, blue, green, or yellow—this switch utilizes capacitive sensing technology to detect finger proximity or contact, triggering an output signal while simultaneously illuminating the button surface via an integrated LED. This dual functionality provides immediate visual confirmation of activation, making it ideal for low-light environments or applications requiring clear user feedback.
Features:
- No mechanical components, don’t wear out, an infinite life, reduce maintenance cost.
- Its sensing part can be placed into any insulation layer (usually a glass or plastic material), it is easy to make and surroundings are sealed the keyboard, to play the role of moistureproof and waterproof.
- The panel design is follow one’s inclinations, arbitrary button size, shape, design, characters, trademarks, such as the perspective window arbitrary collocation, make product integral feeling is stronger.
- Compared with physical keys, touch keys are less likely to damage.
- You can change on the back of the resistance, adjust the signal output is latched output or keep output (see 3.3.2 rainfall distribution on 10-12).
- + 2.7 V ~ + 6 V input voltage range wide, + 3.3 V output signal, can be directly used to drive the relay, optical coupling, LED lights, such as the original.
- – 30 ~ + 70 ‘C temperature range of work.
- A touch sensitive, no lag, time delay, flash and other adverse reactions.
- The built-in anti-jamming algorithm, has good anti-interference performance.
