1. No mechanical components, don't wear out, an infinite life, reduce maintenance cost; 2. 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; 3. 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; 4. Compared with physical keys, touch keys are less likely to damage; 5. 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); 6. + 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; 7. - 30 ~ + 70 ‘C temperature range of work; 8. A touch sensitive, no lag, time delay, flash and other adverse reactions; 9. The built-in anti-jamming algorithm, has good anti-interference performance.
