There are multiple types of doorbells, like wired, wireless, and smart. But we at Lyter specialize in the most demanding kind of bell, and it is the wired door bell. These doorbells are linked to the electrical system of your home. Mostly, the bells ring when you press the switch located inside the doorbell button mechanism beside the door.

The mechanism of the switch and the entire bell saves energy and minimizes the risk of an electrical fire. And the best thing about wired door bell lasts longer with zero or very low maintenance. There is a button on the outside just adjacent to the door. This button is placed around the height of the doorknob and activates an indicating device that is placed inside the building.

So when the electrical door bell or wired door bell button is pressed, an SPST or single-pole, single-throw push-button switch instantly shuts the circuit of the doorbell. A terminal of this button is linked to a terminal on a transformer with a wire. The other terminals of the transformer link to one of the three terminals on the button. A few signaling devices have a third terminal that emits a different sound. If there is one more doorbell button, then it is linked between the third terminal and the transformer.

However, a common indicating device is a chime unit that has two flat metal bar resonators that are connected by plungers operated by a couple of solenoids. Two pleasing melodies are tuned with the flat bars. So when you press the button of the doorbell, the plunger of the primary solenoid strikes one bar, and when you release the button, a spring on the plunger bumps the plunger up.

This lets the plunger strike the other bar and create a ding-dong sound. So it is called a ding dong door bell as well. And if there is a second button to the doorbell, it is connected to the other solenoid with a wire and strikes only one of the bars, creating a ding sound.
