HTTM-SCB CapacitiveTouch Sensor Capacitance Switch Button Module With Blue Light

Great! Love these. You can use them as latching the way they come, or add a resistor to the indicated pads on the back and make them momentary. Very sensitive, worked through .080 3D printed material, when I removed the plastic lens from the front. The softest touch and they work perfect every time

This is a spiffy little capacitive touch sensor. It is small - the product page shows package dimensions of 1x1x1 inch, so just assume it's smaller than that. I dropped on some solder to change it to momentary (easy), and used a voltage divider (advanced) connected to the OUT to keep the LED on (goes from 2.5V to 3.3V when touched) - which is detectable on the ESP32 ADC. Turned out pretty slick!

Mirror on top was not on correctly. Looks like it got hot on the boat from China. I could see it through the package without even opening it. You would think someone would catch that.

Adds a fancy touch to any project ( pun intended ) momentary or latching.
