To turn the circuit OFF, a finger on the OFF pads will activate the first transistor and this will rob the "super transistor" of voltage and the circuit will turn OFF.
1.5v to 9v INVERTER

This circuit detects the skin resistance of a finger to deliver a
very small current to the super-alpha pair of transistors to turn the
circuit ON. The output of the "super transistor" turns on the BC 557
transistor. The voltage on the top of the globe is passed to the front
of the circuit via the 4M7 to take the place of your finger and the
circuit remains ON.
To turn the circuit OFF, a finger on the OFF pads will activate the first transistor and this will rob the "super transistor" of voltage and the circuit will turn OFF.
