Touch buttons have been widely used in the application of large capacity and high visibility products such as portable media players and mobile handheld terminals. Due to its advantages of ease of use, fashion, and low cost, more and more electronic products are beginning to shift from traditional mechanical keys to touch keys.

Existing Customer Application Cases:

● Range hood operation panel;

● Touch switch;

● Handheld home air environment detector;

● Industrial control equipment keyboard with waterproof function;

● Onboard equipment;

● Bluetooth test stand information display.

HTTM Series Touch Key Modules Have The Following Features:

1. No mechanical components, no wear, infinite life, and reduced later maintenance costs;

2. The sensing part can be placed behind any insulating layer (usually glass or plastic material), making it easy to make a keyboard that is sealed with the surrounding environment to play a role in moisture and water resistance;

3. The panel pattern is arbitrary, the size and shape of the buttons are arbitrarily designed, and the characters, trademarks, perspective windows, etc. are arbitrarily matched to enhance the overall sense of the product;

4. Compared to physical keys, touch keys are less prone to damage;

5. You can adjust whether the output of the signal is a latch output or a level hold output by modifying the resistance on the back (see 3.3.2 for details);

6. Wide voltage input range of+2.7V to+6V, and+3.3V signal output, which can be directly used to drive relays, optocouplers, LED lights, and other components;

7. Working temperature range of - 30~+70 ℃;

8. Sensitive touch, without adverse reactions such as hysteresis, delay, flicker, etc;

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