Summary

[edit]
Description
English: This door bell is composed of:
  • thin clear green line: solenoids
  • thin pink line: bell
  • thick dark green line: clapper
  • thin blue line: spring that holds the clapper and that gives electrical contact
  • thick dark blue line: screw for adjusting the electrical contact
  • oval thin red line: contact-area of opening contact

Function:

  1. Without current applied the bell is as shown in the photograph. The clapper is with some distance to the bell. The electrical contact is closed.
  2. When you apply current, the solenoids attract the clapper and the clapper strikes against the bell. The electrical contact opens. An electric arc starts between spring and contact-screw.
  3. The current decreases and the solenoids become too weak to keep the clapper in closed position. So the clapper swings back to initial position and closes the electrical contact again.
Deutsch: Die Teile der Türglocke sind:
  • dünne hellgrüne Linie: Elektromagneten (auf Spulenkörper aus Holz gewickelt)
  • dünne rosa Linie: Glocke
  • dicke dunkelgrüne Linie: Klöppel
  • dünne blaue Linie: Feder, die den Klöppel hält und den elektrischen Kontakt herstellt
  • dicke dunkelblaue Linie: Stellschraube des Unterbrecherkontaktes
  • Oval mit dünner roter Linie: Kontaktstelle des Unterbrecherkontaktes

Funktion:

  1. Im stromlosen Zustand ruht der Klöppel mit etwas Abstand zur Glocke, und der Unterbrecherkontakt ist geschlossen.
  2. Wird Strom angelegt, so ziehen die Elektromagneten den Klöppel zur Glocke. Dabei öffnet sich der Unterbrecherkontakt. Es entsteht ein kleiner Lichtbogen zwischen der Kontaktfeder und der Kontaktschraube.
  3. Der Strom in den Elektromagneten wird zu gering um den Klöppel in der angezogenen Position zu halten und der Klöppel schwingt zurück in die Ruhelage. Damit schließt sich wieder der Unterbrecherkontakt.
