x 587 286 771 292 0 24 powered circuit
x 432 441 640 447 0 24 leakage capacitor
x 326 529 561 535 0 24 controlled light bulb
x 111 77 842 83 0 24 This circuit allows to parasiticaly power low power electronics
x 112 111 847 117 0 24 (like arduino) inside light switch box (where is no neutral line)
x 113 143 849 149 0 24 by leaking little bit of current through bulb when switched off.
x 125 620 895 626 0 24 "switch" can be controlled by "powered circuit" (TRIAC, SSR, ...).
x 179 450 255 456 0 24 switch
x 126 651 778 657 0 24 "leakage capacitor", capacitor across "powered circuit"
x 126 684 900 690 0 24 and "transil" should be chosen to match the load (and light bulb).
x 115 174 863 180 0 24 Please note that "powered circuit" is directly coupled to mains!
