Abstract

Un'unità rotante di complesso di prova di sganciamento per interruttori in scatola plastica stampata consiste di una parte plastica unitaria che coopera con la struttura interna del coperchio d'interruttore per fornire forza elastica di ritorno al pulsante di prova di sganciamento. L'unità di complesso di prova di sganciamento ruota attorno ad un perno e urta la barra di sganciamento di interruttore per articolare perciò il meccanismo operatore di interruttore e separare i contatti dell'interruttore. L'interazione tra un seguicamma sull'unità di complesso e un pezzo sagomato a camma entro il coperchio dell'interruttore riporta automaticamente il pulsante di prova di sganciamento nella sua posizione iniziale a seguito di liberazione.
