Touch Light Circuit

This is a touch sensitive circuit made by using darlington pair of two NPN transistors (2N3904).
Connect a paper clip after the free end of 10 k resistor and when you touch that, led will light up.
For any question, please leave comments.

Kind of pointless being simulated - ironic that we have touchscreens but cannot touch it to trigger it ;)

If you put a switch between the + and the free end of the resistor you can simulate how it would work. But with the npn transistor i assume it's just going to be a momentary switch. Needs a latch and maybe debounce. Pretty snazzy nonetheless.
