seeking teardown info for Quinetic doorbell QUDB

[jkn]

Hi all as per the subject - I would like to dismantle one of these battery-free door bells, but can't find any info on it, to my surprise.

I think Big Clive did a teardown of some switches using similar technology, but not this. The part no is QUDB and TLC have them here:

Thanks for any pointers!

Cheers, J^n

I'm sure one of my friends had a doorbell that ran on clockwork .

And sure enough, you can still buy them.

My old house had the remnants of a mechanical door bell, bellcrank levers and all. This new-fangled electricity will never catch on.

Ah, but you have to remember to wind them. There is a similar type, without the clockwork mechanism. Instead of pressing the bellpush, a caller turns a knob and that is geared to directly drive the bell mechanism.

does it have one of those indicator boards for servants ?....and a cast iron boot scraper

There was an indicator board in my bedsit in Glasgow in the 70s, but it was driven electrically.

Here's an array of servant's bells in a hotel on Islay I took a pic of

. They seem to have different notes by the look.

Clockwork? Really?. I'd have thought a piezo electric effect could be generated on pressing the button to send a tiny pulse via an internal transmitter to some kind of receiver inside the premises. Brian

I have a self-contained wind-up clockwork doorbell. It's not on my door, but I used to use it when rambling in the country to ring at passing cyclists to try and make them feel guilty for not using theirs.

Makes more sense to use a massive great air horn and a battery pack.

My grandparents' house had one on the back door. You wound it up by turning the bell.
