Electric Door Bell

SJVH
Hi all.


I have a Chrome Mechanical Door Bell. (https://www.houseofbrass.co.uk/bells/butlers-bells-pull-accessories/bp32-bp42-pc-butlers-bell-oblong-embossed-bell-pull-mechanical-polished-chrome). I'm still playing about running it flush in the walls with conduits and whatnot.


I am now planning for contingency in case of failure or disappointment with the results. I really like the idea of a modern having a call to the past. Adds character. I really like the idea of the pull knob. It reminds me of my childhood watching repeats of Carry On Screaming on VHS. However if I have to relent and use a push button then I will.


Does anyone know how I could possibly electrify this using a  230V/12V TX or Bell TX. Electronic isn't my area of competency. There is a site on the internet selling a "shaker" but speaking to the owner is costs a lot and has not adaptability and I've heard that the delivery isn't great. I thinking I will need some sort of solenoids.


Please help.


Cheers.

    I'd strongly push you away from mains voltages towards batteries or a low voltage DC supply (e.g. 12V or less, for which mains power supplies are available as ready made units. example of a 5volt one.  )

    To stimulate the old bell pull, a solenoid is not quite the thing - it is too fast and the stroke is very short for sensible power- I have however seen it done for theatre, with a slow moving motor and an offset crank. You need a good inch peak to peak of movement, at a speed of a rev or two per second.

    Something like this motor gearbox combo for hobbyists here  may be a good start. Could be hidden inside any suitable plastic or metal box screwed onto the wall, with just the pull-wire emerging from a small hole and running the last foot or so to the bell itself.

    At the door, then you need to convert the pull wire to a switch,  short length of pull wire into a box, and then a strong spring and a push button on the opposite wall of the box, so as you pull, the button is pushed, may do the trick. Maybe via a block of something with a bit of give, and or solid end stops, so that over zealous operation won't break anything.
