A metal touch sensor is a type of switch that only operates when it's touched by a charged body. It has a high-frequency transistor which conducts when receiving electromagnetic signals.
When it is electrified, at the beginning its original state is low and the LED is on. Touch the module, and then it outputs high and the LED goes out. Touch it again, and it'll output low with LED on, and so forth. To sum up, the output level changes between high and low with each touch.
The module can be applied to many daily electronic devices such as touch table light, touch power switch, etc.
