This bell works according to a very old principle. It is a "Wagnerian hammer". How it works is easy to understand. There are 2 springs in the oscillating system. A spring pulls the lever. The other spring is the contact that interrupts the current. Watch the video and you'll understand. Youtube: https://youtu.be/218BtdXQ9Dc
