| Zusammenfassung: | The embodiment of the invention provides a wireless call button which comprises a magnet assembly, a first upper magnetic conductive plate and a first lower magnetic conductive plate, and the first upper magnetic conductive plate and the first lower magnetic conductive plate are respectively connected with two ends of the magnet. The coil assembly comprises an iron core which penetrates through the first upper magnetic conductive plate and the first lower magnetic conductive plate in a mounting direction. The first upper magnetic conductive plate is arranged between the second upper magnetic conductive plate and the second lower magnetic conductive plate and is attached to the second lower magnetic conductive plate. And the coil is wound on the iron core and is arranged between the secondupper magnetic conductive plate and the second lower magnetic conductive plate. Wherein the iron core moves along the installation direction, so that the second lower magnetic conductive plate is attached to the first lower m |
