How do doorbells work?
In: Engineering
I always thought it was pretty cool how the chime itself works when I first became an electrician.
Simple circuit. Involves a 12v transformer, a switch (the bell) and the chime. The chime uses an electromagnet, 2 metal bars that play a different note when striked, and a metal “striker”
When you press the bell it completes the circuit, bringing 12v to the electromagnet causing the striker to hit the bottom bar (ding) and when you release it the springs push the striker to the top bar (dong).
