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