- Doorbell button round with brass color metal housing, bell wire is not included
- If using as a replacement door bell button, drilling may not be required
- Will work with almost any door bell transformer and wired chimes
- PLEASE NOTE: A diode is needed (not included) if you are using a digital chime (plays a melody; has a speaker for the sound). A diode is NOT needed if you are using a mechanical doorbell chime (a 2-note sound; like a small mallet hitting a metal bar).
