Perfect for Arduino Projects

Works flawlessly with my Uno. Easy to wire and the latching mode is stable. Great for custom control panels.

Good value, minor tuning needed

The module works well but I had to adjust the sensitivity for my thick acrylic case. Otherwise great product.

One pin bent on arrival

The module itself functions fine, but one of the header pins was bent. I straightened it out easily.

Reliable Touch Sensor

Bought five of these for a control panel. All arrived working. Response time is quick and consistent.

5 FAQ

Q: Is this compatible with Raspberry Pi?

A: Yes, connect the OUT pin to a GPIO input pin and share the ground.

Q: What is the maximum current output?

A: This is a logic signal module, not a power switch. Use a relay or transistor for high current loads.

Q: Can this work with 3.3V logic?

A: Yes, it supports 2.0V to 5.5V, so 3.3V is perfectly fine.

Q: How do I change between latching and momentary?

A: There is a solder pad on the back to select the mode. Please check the datasheet for details.

Q: Can I touch through glass?

A: Yes, capacitive touch works through non-conductive materials like glass or plastic up to a certain thickness.
