I was wondering how old fashioned hand crank phones work, in particular: Does the cranking provide power to the phone, or does it just ring the bell on the other end?

Also, how do duplex coils keep the user from hearing their own voice through the speaker?

Skip to main content Window Crank Handles. In Stock. These didn't fit my window so I drilled out the hole on the circular adapter and it works great, the only reason I'm not giving these a 5 star review is because the aluminum is kind of sharp and if you aren't careful you can scrape yourself.
