Touch Module 1-channel - Yellow

A small touch square that glows yellow when you press it with your finger and can pass a signal (touch works capacitively).
This module remains on after contact and only goes out 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.
