Two door bells on one push button switch

Yes, also the length of the additional wire will be a factor. there's a lot of vd on that weedy bell wire.


Anyways. Isnt this all academic as the OP has said

I've decided to invest in a new twin bell system, possibly wireless.

That's certainly another factor. I haven't a clue as to how much current these 'chime' mechanisms draw, do you?

One might think so - but he wrote that quite a while back, and has subsequently continued to have a seemingly active interest in discussions about 'engineered solutions' (which some would probably call 'bodges')!

No idea, but i do remember having to re-wire a TWO BELL solution with thicker wire and a transformer with more grunt.

I don't know about you, but I am rather bored with 4 pages of posts for a bloomin' door bell.

Well (a) none of us have to read it and (b) I suppose it's a change from light switches/fittings, dimmers and garage/outhouse supplies

Thanks for all the postings folks, very informative.

Wire the bells in PARALLEL, else it'll be ****. You can get bell transformers that go to 15v... which is handy if you have too much volt drop as I did.

If wired in parallel, they'll form a closed circuit?

That's true, but it would entail abandoning the internal transformer and using a separate one. As I said, if it were me, I'd start by seeing if the internal transformer in one of them was man enough to operate the chimes in two - since one never knows!

He means to wire just the 'sounders' in parallel, nothing else - which is what I've been saying would be 'worth a try'.

Having started the job this week, I discovered that the transformer for the old bell is external in the loft and not part of the bell unit.

The transformer has 3v or 5v bell supply options.

Didn't wire the the mains side of the new bell, just used the existing transformer feed.

I wired as follows

1. transformer + to bell push wire.

2. return bell push wire to one end of both bell plunger coils

3. other end of both bell plunger coils to transformer - return



Sadly not enough power to get both bells plungers fully active so I need to get either a 6v or 8v bell transformer.

Told you so…..

When I first posted, I thought the old bell had a built in transformer whereas I know now its actually separate so much easier to sought out than trying to link two transformers.



My apologies to all for starting the thread although I've actually enjoyed reading the informative input - as good as techy book from amazon.
