∙ 15y agoHere is a simplified answer that applies to older doorbells that were hard-wired in your home. If you open the housing, you'll notice a transformer that steps the line voltage of your home (120VAC) down to 12 volts. Below the transformer is a wire loop to the button outside, and at the end of that is a solenoid. (A coil that converts electrical energy to kinetic energy via the magnetic field that surrounds an energized wire). When the button is pushed, it closes the solenoid circuit, which causes the plunger inside the solenoid to extend forward. At the end of that plunger is a rubber bumper that bangs into a bell. You'll also notice another bell (or several more) attached to more solenoids that are staggered in action via electronics. One bell is sized for "ding", and another is sized for "dong". More can be added to play tunes or whatever! Hope this helps!

∙ 12y agoThe doorbell switch is in series between a 24 VAC transformer and a bell. When the switch is depressed the circuit connects the supply voltage to the bell and it rings.
