Default Re: Vintage French Doorbell - Surely not 220V AC working!!!

Or you could put a mains - to - 6V transformer primary in series with the bell (terminals beyond reach, of course), and run the secondary winding to the bell push, so when you press the button it shorts out the 6V supply, loading the transformer primary sufficiently to let enough current through to ring the bell
