Timeline for I need to test multiple lights that turn on individually using a single switch. I don't understand the use of diodes in this diagram

Nov 8, 2022 at 8:46 | comment | added | Chris H | +1@RonanPaixão - I suspect these are little indicator bulbs for which drop-in LED replacements have fairly recently become available, rather than room-illuminating bulbs. While we might hope that the manufacturers of said indicators have taken unusual circuits into account (a dimmed state to indicate idle/standby etc. isn't uncommon on panel indicators, and diodes like this could easily be used for that) I wouldn't be optimistic. Still, you should get some light, even if the brightness might not be well controlled or they might flicker; brief testing shouldn't appreciably shorten lifetimes | |
Nov 8, 2022 at 1:04 | comment | added | Ronan Paixão | A lower brightness will probably be sufficient to test the lamps, if they are incandescent or of a similar type. If your lamps are common household LED E27-socket types ("non-dimerizable"/"não dimerizável"), then you might face some problems. Also remember to be careful when selecting the diode: it must support the voltage and current (with some margin). | |
