Hi, I'm trying to power a LED for a switch as indicator.
Yes I know about the dangers.
The switch is 230AC 3 pins, and indicator must be mounted away from the switch.
I have simulated this circuit I found elsewhere and in simulation it works fine, except in real world I get only 1.6V and LED is very dim.
Any ideas? all parts are like in simulator resistors are 1/2W
Well this is for use as indicator light that an appliance is on (LaserJet printer, YES HP forgot to put ON/OFF switch), I could use neon light but I want to use LED. The LED is better because low voltage at the LED side, and it looks better instead of flickering neon. Besides I already have all parts.
If my tread would no be locked at "allaboutcircuits" I would have said that the printer suspends itself after a while and there is not low voltage to connect the led to.
