Can this be achieved by a blocking (isolating) diode?
To explain:
I have 16 indicator lights, each individually controlled by a switch.
This means that only the corresponding lamp lights up when the switch is operated.
The lamps are powered by a 12 volt AC 2 amp bell transformer.
Now I want to add an acoustic alarm.
But since the voltage would be transferred to all the lights via this bell/buzzer, if I'm right there, all the lights would light up and I wouldn't be able to see which switch was activated.
Therefore, my plan would be to solder a diode into each wire so that no voltage flows back to the lamp.
Which diode would be suitable for this?
Thank you for your reply.

Shouldn't it be enough if the Summer has its own ground cable to the power source, or do I think it's too easy?
Look at the picture I inserted. Maybe it's better to miss
Right. The current would flow through all control lights through the connection with the bell/buzzer. There's nothing to do with diodes.
One could insert a cheap transistor in each black line as a switch (must of course be sufficient for voltage and current) and via it the bell/buzzer supply with a separate circuit.
And why can't I just solder a blocking / separating / Zener / other diode?
Sorry if I don't know the name of the diodes. But these diodes do not block the current flow in one direction, so that no current can flow back to the other lamps. Of course, it'd be 16 times if I really think.
Or is it the AC voltage?

I'm not sure.
And could Peppie85 say that?
Why didn't I come to that before?😅 It is necessary to attach one cable from Summer ZWICH to each individual switch and each control lamp. This allows current to flow through the summer whenever no matter which switch is pressed.
Sorry I made a mistake, unfortunately I can't, please forget what I wrote😅😅
you simply take cheap, simple silicon diodes for 1N4007 are cent articles!
Does this diode not only have 1 A load capacity? Or doesn't it matter?
she has, but a little buzzer won't pull as much power. And if so, it was felt to control it via a transistor or a relay.
