Abstract

Interruttore a gravità in cui una sfera metallica (3) è scorrevole all'interno di un corpo cavo (2) di supporto per azionare un bilanciere (15) infulcrato al corpo cavo (2) ed atto a premere un elemento elastico (24) di comando di un interruttore (17). La sfera (3) è mobile tra una prima posizione di fine corsa in cui la sua forza peso è applicata ad una prima estremità (19) del bilanciere (15) per essere trasmessa amplificata all'elemento elastico (24) che quindi chiude l'interruttore (17), ed una seconda posizione di fine corsa in cui la sfera (3) preme su una seconda estremità del bilanciere che si disimpegna dall'elemento elastico (24) aprendo l'interruttore (17).[Figura 1].
