Touch Module 1-channel - Blue

A small touch square that glows blue when you press it with your finger and can transmit a signal (touch works capacitively).
This module remains on after contact and only turns off when it is touched (can therefore be used as on/off switch).
The module operates at a voltage between 2.7-6V DC. The output pin indicates whether the touch surface is being touched.
The maximum current on the output pin is 500mA.
