When renovating her family's Cape Cod, in New Hope, Pennsylvania, Edith Doan left no detail undone, not even the doorbell. "We joked it was the only thing we wouldn't touch," she says. "But one thing led to another, and before we knew it, even the doorbell went." Edith chose a clean-lined bell button in a satin-nickel finish (shown) to complement her new handle and lockset. But the options for electric buttons, which became popular in the 1880s as updates of mechanical bells rung with the pull of a chain or the twist of a thumb turn, are almost endless. Which is why we gathered up our favorites for you: 18 doorbell buttons that offer a warm welcome to guests even before announcing their arrival.
