Isn't what you've written a little confusing? Surely 1 & 2 go to the bell push whether or not batteries are fitted (and also to the transformer/power supply if there are no batteries and power is coming from a transformer) - not just "when batteries are fitted"?The 0F and T3 is the coil for the bell, and the 1 and 2 when batteries are fitted go to the bell push. If batteries are not used, and it uses a transformer instead, the 1 and 2 are handy terminals to join wires.

If bell push to 1 and 2 the transformer would need to go 0F to 1, and a link 2 to T3.Isn't what you've written a little confusing?

Yes, I was for from clear enough.If bell push to 1 and 2 the transformer would need to go 0F to 1, and a link 2 to T3.
Agreed - as above, although my brain knew what I wanted to say, my typing fingers made a mess of it. Apologies.I would say your description is very confusing, I read it "also to the transformer" that would be a direct short when the bell push is pressed.

I am the same, I blame dyslexic problems, I know what I want to say, but it does not read the way I intended. That's the whole thing with a forum, someone proofreads what one has said.Agreed - as above, although my brain knew what I wanted to say, my typing fingers made a mess of it. Apologies.
