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.
