comments
  Early drop switches such as this one were often used to summon the servants to attend to the needs of those people wealthy enough to have an annunciator (call box) in their home. This momentary contact switch is made of wood and the push button and decorative collar (opposite end) appear to be made of bone, or perhaps ivory.
