HTTM Series Capacitive Touch Switch Button Module BLUE

HTTM Series Capacitive Touch Switch Button Module 

HTTM series touch key module has the following features

1. There is no mechanical parts, no wear, infinite life, reduce maintenance cost;

2. The sensing part which can be placed into any insulating layer (usually a glass or plastic material) behind, it is easy to seal with the surrounding environment into the keyboard, in order to play the role of moisture and water;

3. panel pattern arbitrary, button size, any shape design, characters, trademarks, and windows with arbitrary perspective, so that the overall feeling stronger products;

4. Compared with the physical buttons, touch buttons and more difficult to damage;

5. You can modify the back of the resistance, the adjustment signal output is latched output or keep the output level (see 3.3.2);

6. + 2.7V ~ + 6V wide input voltage range, + 3.3V signal output can be directly used to drive relays, optocouplers, LED lights, and other original;

7. -30 ~ + 70 Celsius operating temperature range;

8. Touch sensitive, no lag, delay, flicker and other adverse reactions;

9.  Built-in anti-jamming algorithm, with excellent anti-jamming performance.
