Abstract

Il guarda trama è fissato con il suo alloggiamento ad un binario in modo tale da poter essere staccato. Il filo (2) viene esplorato con un braccio a leva (3) che supportato in modo mobile nell'alloggiamento (6) e che è precaricato mediante una molla a balestra (20). Sul braccio a leva (3) è fissato un magnete permanente (5) direttamente accanto al campo di movimento del magnete permanente é fissata sul binario (16) una sonda Hall (4) che forma un segnale di comando quando il braccio di leva (3) si sposta. In tal modo non vi sono contatti elettrici sul guarda trama i quali devono essere aperti o chiusi. Le linee elettriche che partono o che portano alla sonda hall (4) sono disposte tutte sul binario (16) per cui gli alloggiamenti (6) possono essere tolti o sostituiti senza che si renda necessaria la chiusura di contatti elettrici.
