TOUCH SWITCH 1
To turn the circuit OFF, a finger on the OFF pads can activate the primary transistor and this may rob the
"super transistor" of voltage and also the circuit can close up.
TOUCH SWITCH-2
This circuit detects the skin resistance of a finger to show the circuit ON for concerning one second. The output are often taken to a counting circuit. The circuit consumes no current when in quiescent mode:
This circuit detects the skin resistance of a finger to deliver a awfully tiny current to the super-alpha try of transistors to show the circuit ON. The output of the "super transistor" activates the BC 557 transistor. The voltage on the highest of the world is passed to the front of the circuit via the 4M7 to require the place of your finger and also the circuit remains ON.
