| Aug 10, 2023 at 17:24 | comment | added | Transistor | Ah! CircuitLab generates a PNG image for the schematic and StackExchange allows me to resize the images by adding an 's', 'm' or 'l' for small, medium or large, and that breaks the link. I'll resize another way. Try the simulation links again in a minute. | |
| Aug 10, 2023 at 15:35 | comment | added | Basj | out of curiosity, how can I edit your schematics or simulate the circuits (just for schematic-drawing learning purpose)? When I click the link "Simulate this circuit" in your answer, it doesn't work: is there a way, directly in StackExchange to edit this? | |

Thanks @Transistor. I cannot change the switch for now, and there is just one circuit (no independence). Two bells may overload one transformer and the voltage might collapse: I thought that, if too much current is drawn from one transformer, then it would heat a lot, but still it would work, at least for a couple of seconds. Here it doesn't work at all with one single transformer + two bells in parallel, that's strange! (only one bell rings). Photo of the bell: i.sstatic.net/IRctV.png

| Aug 9, 2023 at 22:15 | comment | added | Basj | Which better/more usual solution would be recommend @Transistor? Either with one single transformer (strangely it didn't work when I tried, see the linked question), or with 2 transformers? | |
| Aug 9, 2023 at 22:13 | comment | added | Basj | Thanks a lot! 1) Given that 2 transformers never have perfectly the same output voltage, does this mean that probably some (little) current flows permanently in the bells (perhaps ~0.5 V), even if the button is not pressed? Is this a problem? 2) How can we know that each bell's return path is its own respective transformer, and that the current doesn't flow to the other transformer? | |
